Whether it's spring, summer, autumn or winter, the body will always need juice. And it doesn't matter what kind of juicer you have: Bosch or Scarlett, Philips or Moulinex, the main thing is to understand the basic principles of assembly / disassembly of this device. So that, if necessary, replace the failed element. Let your juicer serve you long and productive. Make yourself and your loved ones happy every day.
The basis of the juicer is the engine. Today, asynchronous, collector electric motors are used. No wonder - the technician knows no other. Actually, repairing juicers with your own hands of frequencies is faced with the situation of a failed engine. It is almost impossible to replace the mechanical part, devices operating on the basis of meat grinders break couplings, plastic bushings when a bone hits, hydraulic presses have a lot of fiddling with the oil system. Let's consider the questions, do not wait for a detailed guide, but we will consider the main types of faults in sufficient volume.
We hope that reading the review will help our readers to fix the juicer of their choice on their own. Nothing complicated inside. Don't be intimidated by the upcoming renovation of Scarlet's juicer.
Repair of the Rossoshanka, Santos juicer - the difference in the price of the product is 30 times - there is a motor inside. Rossoshanka does not work for long, noisy, the essence is the same. The properties of the juicer are determined by the design of the mechanical part.
The advantages of induction motors are considered to be simplicity of design, maintenance, high efficiency. Less noisy than collector ones, however, when powered with a voltage of 50 Hz, it is difficult to get rpm above 3000 rpm. Juicers consider this a serious limitation, Santos has a fairly large centrifuge diameter.Let's describe Rossoshanka, Neptune, and other domestic high-performance juicers in a similar way.
Manifolds are devoid of restrictions, they turn out to be smaller in size. Lose in other important professional juicers:
On the shaft of electric motors, we see impellers blowing over the stator coils. It is made to cool the windings during operation. If, when disassembling the juicer, it was found: there are no elements inside, it is possible to supplement the structure by wisely choosing the shape of the blades. Will soften the thermal modes of operation of the electric motor. From the above it follows: asynchronous motors are preferable for the manufacture of high-quality juicers, it remains to solve the problem of speed.
In the case of centrifugal models, the issue is leveled by an increase in the diameter of the working chamber. As a result, with increasing distance from the axis, the centrifugal force increases. It is permissible to reduce the speed of the juicer motor without loss of quality.
Each device is supplied with a set of speeds. In asynchronous motors, it is realized by proper separation of the stator coils. Not all work at the same time, the result is a variation in speed. The scheme is often implemented, it consists in the correct commutation of the electrical circuit with buttons. The technical solution has great reliability, durability, and fault tolerance. A positive point. As for the speed, you can increase it using an inverter in the circuit. It is clear that it will lead to a rise in the price of the device at times. Smooth speed control can be achieved.
As for asynchronous motors, it's easy to do. Amenable to adjustment, avoiding complex circuits. Losses are reduced if the windings are supplied with direct current. Inductive resistances have little effect. The minus is small: a complex power supply is required, which reduces the efficiency of the juicer. The listed key points must be clearly understood if there is a desire to replace the engine. Readers can insure against winding burnout by bothering to include a thermal fuse at 135 degrees Celsius in the circuit. The element must fit snugly against the winding. Ideally, the thermal fuse is recessed between the turns of the wire. Provides heat exchange.
Forced cooling will not interfere. How it is done in the case of juicers, any devices, have already been told. You can borrow an induction motor starter relay from the refrigerator, along with the motor. There are two subtleties here:
There is a weak point in cheap juicer models: they are not protected against engine burnout. Why not put a relay like a companion for refrigerators. A difficult question, we leave it to the readers to decide on their own. The cost of other freezers is an order of magnitude (!) Lower than top-end juicers. The refrigerator works day and night, avoiding begging for the required break, does not turn off in summer. The power of the device is considerable.
For our reasons, reliable technology is closer to nature, figuratively speaking. This is directly confirmed by the design of the Norwalk juicer. So in a refrigerator, often all sensors have nothing to do with electrics, much less electronics. We need more bimetallic plates, thermocouples and other reliable and simple equipment. By the way, gas water heaters do just that, even ignition on a piezoelectric element. In this case, the technique works for a long time, is reliable and efficient. Overheating of the windings is easy to assess by the temperature of the magnetic circuit. Why isn't it done in juicers? Unable to answer this question.
What about Norwalk? Do-it-yourself juicer repair in this case is closely related to hydraulics, which was already mentioned at the beginning. Design:
Thanks to a clever solution, the compressor is devoid of electrical parts. Steel block with spacers. The motor, on the other hand, is made in the best traditions of the machine. One glance is enough to understand: in 5 minutes it will not ask for rest, imitating Zelmer. In light of the above, we believe that it is enough to find a Norwalk screw juicer attachment instead of a meat grinder, having received an excellent device for a long-term operation. According to domestic GOST, it means that the equipment can withstand merciless operation during a work shift (8 hours).
The hydraulic unit will need to be filled with new oil periodically. The old is merged first. After removing the cylinder cover, it is supposed to remove the internal mechanism with a return spring, scoop out the oil. Keeping the position, the compressor drive starts. Gradually the oil will be in the cylinder. The new is poured three-quarters of an inch below the lid. Will the air gap interfere with the work? Masters say: powerless to harm. You will need to track fittings, compressor, cylinder leaks. Add, the return of the table to its original position is carried out by a spring after pressing the handle of the release valve.

If it comes to attachments for meat grinders, you will have to change plastic gears and couplings. They come in a quantity of 2-8 in a set, sometimes you have to buy new ones. Steel gears of meat grinders-juicers are rare, there is a chance of failure of a precious engine. You wonder how industrial units work ...
It is clear to readers that the main types of faults relate to the engine. First check the power supply, then the continuity of the windings begins. Having localized the malfunction, they try to rewind the coils. In the case of a collector motor, doable, the stator is a dull choke strung on a magnetic circuit. The manifold motors are called for each position of the section until the drum completes a full revolution. The rotor of the squirrel-cage induction motor is incapable of burning. The current is small, copper wire is often inseparable from the base of the "squirrel cage" by insulation. The device of the juicer is so primitive, the mechanics (bearings, oil seals, gears) and the drive break down.
They talked about the repair of power supplies more than once. Impulse sources are found in expensive models equipped with the rudiments of intelligence.
To fix a juicer yourself, you need to know the type of device and what kind of motor is inside. If the breakdown is associated with the engine, then you can repair the product yourself, depending on the complexity of the problem. But in some situations, every housewife can independently repair the juicer.
What types of electric motors are there?
Regardless of the cost of a juicer, if there is a motor inside, then its structure is very similar. The only difference is that cheaper models are noisy, while products of higher cost emit less noise. The specific properties of the juicer, with the exception of the noise level, depend on the mechanical design.
In juicers of cheaper models, the motors are most often asynchronous. They are distinguished by simplicity of design and maintenance, and have high efficiency. Such motors make a lot of noise and require a sick-diameter centrifuge. There are brushed motors that have no restrictions. The juicer with these motors is smaller.
The electric motor shaft includes impellers that blow the stator coils. This is necessary in order to cool the winding during the operation of the devices. Some people disassemble juicers and see that there are no described elements inside. In such a situation, if courage allows, the design can be supplemented with them yourself.It is important to choose the correct shape of the blades and such an addition will soften the thermal conditions of the engine.
Some modern juicers have a centrifuge. Due to its presence, the diameter of the working chamber must be increased. This causes the centrifugal force to increase, reducing the engine speed. Juice quality will be slightly lower.
What can break in a juicer?
The easiest way is to fix the attachment yourself. Replacement of the plastic gear or clutch is often required. The set of these elements can be from two to eight, if necessary, you should purchase new parts. Steel gears in juicers are rare. If they fail, then buying new products will cost more than buying a new household appliance. Typically, steel gears are found on large industrial units.
The main malfunctions will relate to the engine, it is for this reason that so much attention has been paid to its design in this article. First, the power is checked, then the winding. If there are problems with the winding, then you must try to wind the coils again.
Brush motor problems are easier to troubleshoot. After all, the starts in such models is an ordinary choke strung on a wire with a magnet. For each section position, these motors are started separately. Therefore, until the drum completes a full revolution, it will be possible to diagnose the malfunction. In an induction motor, the rotor cannot burn out due to the fact that a current of sufficient strength does not pass through it. But the copper wire may separate from the base. The juicer looks quite solid and dimensional, but its design is so primitive that in most cases only the mechanics or the drive breaks down.
It is possible that a hostess without experience in disassembling and assembling household appliances will find it difficult to deal with the mechanics of a juicer. In such a situation, you need to turn to one of the men, because, the basics that are described in this article, they are taught at school at work. If it is difficult to fix the malfunction on your own, then it is better to go to a service center.

After surfing the Internet and getting a lot of information, I looked for an inexpensive Moulinex Frutti Pro Plus juicer.
This miracle of technology was purchased in one of the Kaluga stores, but it did not please me for long. At first, it turned out that the filter itself does not clean itself (at least when pressing the chokeberry), so you constantly have to remove and clean it by hand.And when the next portion of rowan was squeezed out, the juice-squeezer turned off by itself and did not want to work. At first I thought that the thermal protection of the engine worked, but after an hour, the equipment still did not turn on.
And this is after 2-2.5 hours of work from the date of purchase, I am furious. At first I didn't want to leave it in the box, take it back to the store and shove it at the saleswoman who praised it to me.
Then he cooled down a little and gave up this thought - somehow not like a man (and the saleswoman is pretty, it's a pity), washed the broken device with the thought of how I would carry it under warranty and how they would deny me this very guarantee, in general I scrolled in my mind options for a verbal skirmish (I had no doubt that it would be).
On the same day I went to see my aunt, took a juicer from her, and the next day gave the remnants of mountain ash. I didn’t take my sokozhmalku to the service, then there’s no time, then I’m reluctant to lug a large box in a transport, and it’s too far on foot. So she got it until January, and that's when I started to repair it. She died quietly, no sparks, no specific smell of burnt insulation, so I decided that either something had fallen off, or some part of the electrical circuit was out of order. I unscrew the four screws on the bottom cover and remove it.
Yes, a very complex electronic product.
Electronics ”of this juicer consists of:
2.operating mode switch low speed / high speed
3.diode, when the switch contacts are open, the diode passes only one half-wave of the mains voltage to the motor, so the motor runs at half its power, when the contacts of switch 2 are closed, all the current flows through these closed contacts in full and the motor operates at rated power
4. switch that actually turns on / off the device I want to note one discrepancy right away: the tag on the case says 400W, the engine has an inscription 600W, I didn't check which inscription is true, maybe then somehow.
Having called the entire circuit with the tester, I found a place, an open somewhere between the terminal going to the noise filter and one of the rotor brushes. So all the same the engine.
He unscrewed the four screws securing the motor to the case, unscrewed (clockwise) the drum from the motor shaft, during this operation, on the other side of the motor, a slot was made on the shaft for a screwdriver, and pulled the engine out of the case At first I thought that a thermal fuse was hidden in the stator winding, which died ...
I opened the heat-shrink tubing and found a coil that filters interference. Then I accidentally pulled the wire from this coil onto the brush, and it turned out to be torn off from the brush holder (the core was torn off, and the insulation was clamped by the brush holder petal). So this is where the dog rummaged. I soldered the wire, put the coil in heat shrinkage, checked it - it works.
Video (click to play).
I put everything back together, checked it again - and it works like that too, well, that's nice.
