What can you do with a blender motor. Large Powerful Drill Blender

We do not always throw things away at once, many have irons, hair dryers, and some other household appliances in the closet. And it is quite possible to find an old one, maybe even still working, which was replaced with a new modern unit. And it's good that we haven't thrown it away yet, because we have found some tips on what you can make from an old mixer for your home.

How to make a table grinder from a mixer?

You can make a grinder for sharpening knives or other objects only from a working mixer. For this we need a part of the case with a motor. It is good if it is a stationary instrument with a removable portable flask. The process of reincarnation will take place as follows.

If the mixer was initially set up to operate at multiple speeds, all sharpening and polishing must be done at maximum speed. It will be more productive.

Figure 3 Second life to a mixer - sharpening tool

Connecting equipment to foot control

It is not always convenient to select and control manually the speed of new equipment. You can add a pedal to the sander as follows:

• disassemble the case;
• disconnect the electronic control;
• connect the motor directly and connect to the pedal.

However, you need to know that not every model is suitable for connecting to a new device. Improperly selected equipment will overheat the engine and damage it. All this can result in a short circuit. It is not difficult to calculate the required power, each product has a label indicating the nominal parameters.

To calculate the optimal pedal load current, divide the mixer motor power by the mains voltage. In our case, these are:

• 700 watts / 220 volts \u003d 3 amperes.

If the pedal has a factory rated load current higher than 3 amperes, such a connection is quite feasible.

Such a device is suitable for sharpening household knives, meat grinder knives, household tools, and can be used for polishing wooden, plastic or metal objects.

Drill machine from a working old mixer

The engine in the old mixer has good power, its performance has been tested by time. You can make a boring machine useful in everyday life with your own hands, for this you will additionally need only a motor from a portable mixer, 2 cans: for coffee and a freshener, the diameter of one should be slightly larger, and a small piece of decorative leather.

The step-by-step conversion process is as follows.

Figure 5 Motor from a conventional mixer

1. and remove the 220 volt motor.
2. The fan must be moved as close to the motor as possible, for this it is necessary to remove all unnecessary elements that are fixed from the fan base to the shaft housing. They do not carry any functional load on the future product. After that, it is necessary to screw the fan to the end of the shaft leg.
3. Next, you need to cut off the top from the can from under the freshener to the beginning of the narrowing point.
4. The cut top should fit perfectly into the opening of the second coffee can. For reliability, it can be fixed with cold welding and wait until it solidifies completely. First, you need to make small holes at a distance of 2-3 mm from the edge in a circle, which will serve for additional air exchange during fan operation.
5. After the welding has solidified, it is necessary to insert an empty bearing of the same size into the remaining hole for future fixing of the bur, then carefully press the hole with a hammer. After that, cover all the voids from the inside with epoxy resin.
6. Cut a rectangular hole in the can for the control output to the outside. Then insert the motor inside the housing and fix it on the metal frame, which should be welded first or used from available tools.
7. To close the bottom, you can use a metal drain from the sink, the holes will serve for additional air exchange. It should be welded using liquid welding.
8. After assembling the equipment, its body should be refined with a skin flap.

In the finished drill, you need to put a washer on the nozzle to the shaft or tighten any fastener. With our own hands, with zero investment, we got a universal device with which you can create real masterpieces in everyday life.

Figure 6 You can find many applications in the home of the drill

We make interesting objects from the flask

If it is equipped with a flask without cracks, and it is still in good condition, you can make a candlestick that will bring comfort and coziness on winter evenings. There are a lot of manufacturing options:

There are a lot of decoration options, you need to choose one that fits into the style of the room.

Figure 8 For external decoration, you can use special paints

Dismantling the mixer

If the mixer no longer works, and we have already invented the use of the flask, there is no need to rush to throw away the housing with the motor. You can take it apart and pick up something useful for future rework. The disassembly process must be carried out as follows.

1. Loosen the connecting screws with a screwdriver.
2. Determine visually the cause of the engine malfunction in order to understand which of the internal parts or assemblies may be useful later.
3. From an idle engine after disassembly, you need to pay attention to the following components and elements:
   • mode switch;
   • indicator light;
   • engine. If disassembled, the rotor and stator can be used later;
   • wires;
   • coil with copper wiring;
   • network wire.

So, in the end, the good old mixer can serve as spare parts in future alterations.

Figure 9 Disassembling the old mixer

Hand-made things are not only saving money, they are also a manifestation of creativity. After all, it is much more pleasant to use a tool in the manufacture of which one has invested one's soul. Do not rush to throw away old things, you can always find a use for them and give a second life to your once beloved equipment.

Figure 10 Second life to an old mixer

The blender is a motor equipped with a nozzle. Nothing complicated. A bowl with a knife is pushed onto the output shaft of the electric motor, the engine blocking is turned off. The assembled device is started by the power button in cruise or pulse mode. The process is assisted by a speed regulator, a cord with a plug, less often a fuse. It is not difficult to disassemble the blender, the main thing is to assemble it later. Can you handle it? Doubters read on how to repair a blender with your own hands. We recommend that you avoid jumping over sections.

How the blender works

Nature has created three varieties of blenders:

1. Stationary.
2. Manual (submersible).
3. Complementary composition of the food processor.

The blender device in each case provides for the presence of an electric motor - the initial driving force, the principle of operation changes according to the tasks performed. Stationary blenders resemble replenishment combines. You will see two characteristic prefabricated units that help the device perform its duties:

1. Engine.
2. Bowl with a knife.

Let's talk about how the product works. The knife rotates quickly in the bowl where the food to be chopped is placed. A specific blade causes the content to move along a closed path. The knife is located at the bottom. When the electric motor transmits torque to the blade through the output shaft and the spindle, the speed of the latter increases rapidly. Due to the speed (thousands of revolutions every minute), the effect of movement of the crushed mass is obtained. The envelope of the blender blade resembles a propeller. The crosspiece pulls fruits, vegetables onto itself from above, throws chopped pieces to the sides.

Then the profile of the bowl enters into the right, twisting the movement of the food mass. The walls expand upward, so under the pressure of the stream coming out of the knife, the mash begins to crawl upward. In the center, pieces of food fall down. The processed mass reaches the lid, falls back on the knives. The described process proceeds at an uncontrollable speed.

This cycle occurs ideally in strong blenders. Cheap household models do not have enough revolutions to establish a closed movement. The knife cuts through the void. Therefore, wanting to chop the cabbage, the cook has to add water. The step releases the laws of hydrodynamics that come into force, the work of knives is facilitated. Therefore, the first thing! Before fixing the blender (which may not have broken):

• If a low-power blender does not want to grind the mass, the fact does not mean a 100% malfunction. Try adding water, milk, juice, and repeat the process.
• A simple fact means: the blender has a dull knife, the speed switch is broken, the engine lacks the necessary power. The masters say: the problem affects the cup. More precisely, it lies in the rotating joint of the knife.

Replacing the blender blade

As for the blender knife, it is unlikely that you will be able to sharpen the blade by hand at home. Buy a new one, there are 3 options for the development of events:

1. First, the knife is sold as a separate spare part. In this case, remove the old one. An old towel will help, clean. We grab the blender knife with a rag, unscrew it from the spindle. Please note: the thread is left-handed, so you need to twist in the other direction than traditionally. It happens that the knife is impaled by means of several nuts. A wrench and pliers will help to remove the accessory from the blender. The bowl is removed from the output shaft, the plug has left the socket. A rotating blender knife will easily disfigure your fingers; it will be problematic for doctors to reassemble. It happens that the knife is sold with an oil seal, change both parts.
2. It happens that to dismantle the knife, you need to disassemble the blender bowl. A rare case. Replacement occurs by the described method, take the trouble to update the oil seal covering the spindle.
3. Finally, it was found that the bowl was not separable. See how to proceed. For such blenders, you will have to change the bowl together with a knife and an oil seal.

Blender speed controller

Frequent problems with blenders are related to the speed switch. Only the master can fully check the performance. If you have knowledge of radio engineering, try ringing the part first. It will probably be immediately clear if this is the reason for the strange behavior of the blender. The switch is removed from the device (soldered), the positions are checked in full. Naturally, during normal operation, the contacts must alternately short-circuit, switching the corresponding windings of the electric heart of the device.

Try the method described above in parallel. Turn on the device, listen to how the engine will behave, working out fixed speeds. The regularity is characteristic: the blender knife moves faster, the buzz is stronger. Advanced models have a lock against switching on without a bowl.

Note that the safety part was introduced in the 20s of the twentieth century, when the blender was just invented. The patent applicant emphasized that the engine starts when the bowl is installed. Therefore, we consider the option to be classic to the fullest.

Blocking mechanism The noted reason for the blender to stop. What else is being repaired ...

If the blender stops

It happened that the device refuses to work. The situation is solved easier than in the case when the blender is too lazy to cut, does not grind.

First, we strain our ears by turning on the device. If a buzzing sound is audible, it is probably a stuck knife. Remove the bowl, gently squeeze the power lock button with your finger (pencil, pin). Earned - business is limited to a bowl, a knife. How to fix the problem, they told. Much more interesting is the atypical case: a buzz is heard, the blender will be overwhelmed even with the lock released. Surely the reason for the motor is the winding burned out. Here the result is determined by the cost of the question, if there is a way to get a new engine at a reasonable price, it is worth replacing. Cheap models make you reject the idea of \u200b\u200bfixing a blender yourself.

When no buzzing with the turned on button is registered, we examine the power supply path:

1. First of all, we check the presence of voltage in the outlet. Practice shows that most problems are solved at this stage. A blender, like other household appliances, breaks down relatively rarely. Plug in a known working table lamp or equivalent. If ok, go to the second procedure.
2. To check the cord, disassemble the blender body. Turn off the device from the network, take a screwdriver. Rare foreign models will require special heads. Discard the cross, flat screwdriver (slot). Inside the blender is a power block carrying a soldered or screwed cord. We check the voltage with a voltmeter, or we take a deliberately working cord, connect it, try the assembly. The place of failure is localized. In some severe cases, tension cannot be measured. Less usable contacts are closed with plastic, non-separable. Those who avoid shredding the device take a needle, a wire is soldered to the tip. You will need two homemade gizmos. Turn off the blender from the network, pierce both cable cores with needles, connect the tester terminals. We make sure that the lines do not overlap each other, we keep our hands away, we cut into the network. We look at the result on the tester display.
3. These actions are simplified if the fuse is inserted in the blender. We take out and call. A breakdown is identified - we visit the store, we buy a new one. The parameters (power, current) are inscribed on the glass (ceramic) case. We use the numbers when choosing the desired product in the store. Avoid trying to make a makeshift fuse option, a rash step will surely cause a fire. New is inexpensive. In the open circuit with a tester (multimeter), measure the applied voltage. When there is nowhere else to measure the mains voltage (230 volts), the fuse slot is fine.
4. It happens that a new fuse breaks down instantly. A short circuit has occurred inside the blender. The malfunction affects the integrity of the motor windings, electronic circuits. We try to connect energy consumers one at a time to the source, and observe the result. Craftsmen recommend using a homemade bug that can withstand the resulting electric current. We connect a multimeter, measure the amperes. The operation is done extremely quickly, otherwise there is a chance that the traffic jams will be knocked out at home. We use the measured value to calculate the power. If the figure obviously exceeds that indicated in the passport, the faulty unit is found. As mentioned above, problem blocks: blender motor, circuit boards.
5. If the described operations led to the belief that power is available, we undertake to inspect the printed circuit boards. We examine capacitors for swelling, resistors for signs of burning. Tracks should not be torn or peeled off the backing. Found a defect from the listed symptoms - the cause of the blender malfunction is limited to the electronic filling. In the event of a short circuit in the motor, the technique cannot be restored. Defective winding insulation.

Hand blenders

In hand blenders, collector motors are often used, motors can be powered by DC and AC currents. In simple models, power buttons are available, directly the contacts of the brushes. For spark extinguishing, capacitors are attached to the rotor. Let's say more, in addition to capacitors, varistors that short-circuit voltage surges, protecting the windings against combustion. In the simplest models, thermal fuses are placed among the turns. If it burns out, the components should be replaced with new ones. The circuit is used in motors of collector and asynchronous types, transformers. Do-it-yourself blender repair requires knowledge of the unwritten fundamentals of electrical engineering and electronics. Here are the basics - knowledge - today we will do it.

The interior of hand blenders

Collector motors are equipped with stabilization circuits, but the simplest blenders are devoid of sophistication. Varistors constitute an important component of many devices; they protect not only motors. In switching power supplies, overload disconnection of high frequency generators occurs with a short circuit to the fuses. The result is a protection trip. A malfunction is identified by replacing the fuse with a light bulb: on - the power is turned off, continuing to search for problems.

The simplest collector motor is formed by a pair of stator windings, a good bunch of rotary ones. A drum is placed under the brushes, broken by sections. Each pair of opposite contacts is equipped with a closing coil. Making sure the blender is working properly, ring each one by rotating the shaft by hand. Bearings are often considered a weak point. There are two nodes - front and back. The lion's share of the load falls on the latter. HADO is used for lubrication. After application, the composition induces the formation of a ceramic film that temporarily improves glide while protecting the surface.

In hand blenders, such solutions are used with reluctance, the switching element gets very hot, and there is simply no place for a huge radiator. However, using a simple speed control, make life much easier for the hostess.

Underwater reefs identified:

1. Sharp changes in voltage consumption require filtering (surges) along the power circuit, causing sharp drops in the external network. The effect is noted when running on a generator.
2. Speed \u200b\u200bcontrol is a valuable quality, but if the power rises sharply when kneading the dough, the blender will snatch from the hands of the hostess, good is not enough. It is more useful for calm women to buy a blender at home that produces constant power regardless of the dish being prepared.

In advanced models, the blender device is complemented by speeds. More often we see separate buttons that are pressed continuously, forcing the engine to work. It was done for a reason. The developers realize: a weak female hand quickly gets tired, therefore, the key will most likely be released before the engine burns out. The adjustment method is often not unparalleled in complexity. The output voltage is removed by paired secondary windings of the transformer. A change in speed occurs.

Blenders often burn if varicaps are protected against power surges, thermal fuses protect the equipment against overheating. An element with a threshold of 120 degrees is placed in the power circuit. At times, a thermal fuse is placed between the turns of the motor (mentioned above). The switching power supply works according to an ordinary scheme. At the input, the voltage is filtered by capacitors, chokes, resistors, the signal passes through a high-frequency power transistor (even two). The process is controlled by a microcircuit generator that supplies voltage to the control gate. At the output, the voltage is filtered if necessary, less often rectified.

Frequent breakdown is winding burnout. Try to buy products with fuses. Simplify your own life beyond words.

Brush motors are controlled with a voltage cutoff when a smooth transition is required. In the case of two or three fixed speeds, there is probably no need for such a scheme. A sinusoid along the positive and negative half-wave is truncated to a certain section. The effective value decreases, naturally causing a decrease in the shaft speed of the collector motor. As already mentioned, kitchen appliances are often equipped with trivial controls. It is unlikely that the repair of the Vitek blender will require a deep knowledge of circuitry.

We add that we noticed reusable thermal fuses that, after being triggered after a specified period of time, restore the circuit. Others are designed for 100 work cycles. Decide for yourself whether the resource of functioning is sufficient for your own view of the device. Let's list what can break (power supply):

• filters;
• diode bridge;
• transformer;
• generator;
• key transistor;
• rectifier output diodes;
• varicaps;
• circuit breakers.

Do-it-yourself blender repair will require knowledge of the basics of electronics. Nothing complicated, according to requests in the comments, we will create a topic describing the topic of power supplies. Anyone in the jet will repair the blender on their own without any problems.

Features of desktop blenders

Hand-held appliances lack the important ability to make cocktails that people like. You need a table blender equipped with a large bowl. At the bottom there are cruciform sharp knives, the junction is a real disaster. The motor stem is topped with a relatively soft lower half of the drive clutch. A ring formed by dense rubber, the perimeter, forming a crown, are teeth. Each fits into a corresponding recess in the upper sleeve. The lower half is devoid of rigid threads. Remove the part with a screwdriver and a hammer, hitting the teeth, setting clockwise rotation, the masters recommend carefully prying the coupling, pulling it up. Then a new part is screwed counterclockwise. The thread is, of course, left.

The clutch is a critical part that protects the engine of the unit against overloads. When the knives are jammed, you will hear a clicking sound. Be too lazy to turn off the blender - after waiting for a while, the lower half of the coupling will become disabled. The problem with the upper half is that the seals sometimes leak. Seeing an unfavorable situation, get ready to disassemble the device. Using your hands, unscrew the assembly of knives from the bottom of the bowl. The rubber pad is set aside.

The upper half of the blender sleeve is screwed onto a knife-seated stem, left-hand thread. The direction of rotation of the knives is recognized by the front sharp edge. Grip the large adjustable wrench through the towel (cloth) of the blade in the stem position, twist in the opposite direction of rotation. A pair of rubber sealing washers, one steel, is attached under the upper half of the coupling. Both varieties are removable, the knives can be removed from the assembly. The blender blades are sharpened if necessary. Please note: there is an additional double rubber seal on the inside of the bowl. Replace parts with purchased ones or those that you can get hold of.

The reassembly of the blender is carried out in a similar way. Remember: the thread of the coupling is left. Tighten the nut while avoiding knives. Be careful not to cut with the blender blade. The motor in the base under the bowl is not much different when compared with manual models, but it can withstand loads better. Often speeds 2-20, the simplest food processing programs are laid down.

Blenders are often sold as part of food processors. The knife shaft is driven through the gearbox. Protection against turning on is mechanical, the drive shaft (cutting, shredding) is located separately, at the same time it does not rotate with the side one. The rotation speed of the blender, of course, is higher, a step-up gear is required.

The presentation is over today. The presented models of good are similar to each other. Knowing how to repair the Tefal blender, the master will master the repair of the Scarlett blender. Further more, the manufactured household appliances are similar to each other. Readers may not have heard, but 85% of washing machines, like blenders, are equipped with commutator motors. Therefore, the repair follows the same pattern. In our case, speed control is provided by the design. The advantages of collector motors in terms of regulation over asynchronous motors are obvious. In the latter case, the stator winding is often divided by a fixed number of sections. This method easily reproduces three speeds; the layout is not suitable for advanced solutions. The washing machine only on the spin has 3-5 speeds. A circuit that contains a power switch with a current cutoff mode just suggests itself.

This is why blender repairs are similar. Connoisseurs of coffee grinders, drills, screwdrivers, mixers and even vacuum cleaners will perform the necessary sequence of actions without noticing a change in the type of technology.

This is how they repair the blender themselves. We recommend that you repair the device under warranty, disassemble an expensive model only if necessary. Consider the approximate border of cheapness in the amount of 3000 rubles.

We decided to make squash caviar. The question arose, how to grind zucchini?

Blendertoo small and weak for such tasks, and a meat grinder is not able to grind into a homogeneous paste.

Small lumps remain, and the caviar turns out to be grainy. Therefore, I decided to make a large and powerful blender out of a drill that every DIYer has.

The design is so simple that it does not require any drawings and is done literally on the knee.

Materials and tools

• Drill. (every DIYer has it);
• PVC pipe 50 mm (plumbing store);
• PVC pipe cap 50 mm. (same place)
• Chrome metal tube with a diameter of 16 mm (furniture accessories store);
• Plastic dowels 14 and 8 mm. (building materials store);
• Self-tapping screws 16 mm with a wide head (ibid.);
• M8 and M6 screws. (in the same place);
• Editing knife blades (household goods);
• Clamp 50 mm (ibid.);
• Empty tin can (trash can)

Making a blender

1 - drive, 2 - housing, 3 - knife shaft.

Since an ordinary drill acts as a drive, we will consider the remaining 2 nodes.

Making a knife shaft

A 14 mm dowel is driven into one end of this tube. and the next 8 mm dowel is driven into this dowel and 8 mm into the dowel. screw M6. Since it is impossible to clamp a 16 mm tube directly in the chuck of an ordinary drill, in the opposite end, we also drive a 14 mm dowel into which an M8 screw is screwed. Leave the 30 mm protruding screw for the clamp in the drill chuck, cut off the rest. Only in this version it is necessary to take into account that the optimal length of the knife shaft (without the knives and the part that is clamped in the chuck) is 100 mm, and the length of the dowel 14 mm is 80 mm.
it makes sense to shorten the dowels to 50 mm.

Manufacturing of the case

The body is made of PVC pipe with a diameter of 50 mm, a plug for this pipe, and a tin can. And another collar.

Cut off the thickening for the rubber cuff from the pipe socket, since it is not needed.
Next, take a suitable shallow empty tin can and drill a 1 - 2 mm hole in the center of the bottom. larger than the cutter shaft diameter. We drill the same hole in the center of the plug. We drill several holes with a diameter of 10 - 12 mm around the perimeter of the can for the exit of the ground mass (It is much more convenient to drill holes in the can with feather drills on wood). We combine a tin can with a plug, and fasten it with self-tapping screws.

We measure the length of the knife shaft fixed in the chuck, and adjust the body to this size. In the upper part, we make 2 slots 30 mm deep.

Since the inner diameter of the pipe is slightly larger than the diameter of the drill neck, a gasket is needed, which we will make from the remainder of the same pipe. We cut off a ring with a height of 20 mm and from this ring we cut out a section of 15 mm. We glue the ring on the inside of the extension cord so that it does not get lost.

We glue on one point so that there is a possibility of squeezing. Next, we apply the extension cord to the drill neck (or simply measure it with a ruler, which is somewhat more accurate :), mark the location of the key hole on it, and drill it with a 20 mm drill.

The body is ready.

By the way, I forgot to write. If there is no suitable empty can at home, you can replace it with any suitable lid, or use a 100 mm pipe plug. Which will look much more "firm" :)

We put the body on the drill, until it is completely secured, insert the knife shaft into the pre-spread cams, turn the body until the key hole on the body coincides with the socket on the chuck, tighten the shaft with a wrench, and finally secure the body with a clamp.

All. As they say, the design does not require adjustment and starts working immediately when turned on.

It also grinds potatoes for pancakes into a homogeneous mass, which previously had to be manually ground on the smallest grater, because the meat grinder leaves lumps, apples for applesauce, crushes nuts for cookies and much more.

P.S. Since I had a steel tube with a diameter of 10 mm, which I cut off from the next leaking heated towel rail before throwing it out, I used the second option when making the knife shaft.

As a rule, we throw away kitchen appliances that no longer function. Take, for example, a blender that's already out of date; there really is no other way for him but to be sent to the trash. However, don't throw away this broken blender!
This DIY project is for you if you think throwing away broken equipment is useless waste. In the video below, you will learn how to use an old blender and remake it to become a decent drill or even an engraver!
The blender motor is powerful enough to handle light drilling and engraving jobs, so instead of throwing away your blender, why not repurpose it so you can still use it for your future projects? Watch Evgeny Budilov's video and how he successfully turned his old kitchen blender into another useful tool.
Don't throw away the blender! Repurposing old products at home is one way to save money, in addition to reducing waste in the environment and giving you an extra tool to use at home.
