The screwdriver sparks inside and smokes

The screwdriver started smoking, what should I do?

Greetings! People, who has experience in repairing screwdrivers?

Mine has long since started to slow down in the power transmission under slight load, and yesterday it actually tightened a couple of screws and started smoking.

I took it apart today, cleaned everything, removed the brush assembly, and washed everything inside. There are still plenty of brushes. I connected the motor cleanly, but the brushes sparked strongly and began to smoke.

Tell me, is it possible to fix it... why can it spark so much?

Well, that’s understandable... I’d like to get by with a little bloodshed. Moreover, it’s not a fact that the gears are in order - it’s been broken for a long time already.

What is faulty in the gearbox can only be determined after disassembly and troubleshooting. It is quite possible that even the gearbox is working, but the switching latch has simply worn out, so the speeds have gone out. The same crunch can happen when the speeds are not switched on. But replacing the engines is a small matter... Because looking the malfunction in it is such swearing, the ovchilka is not worth it in short. If a Ketai engine with 12 volts costs around 500-600 rubles. Well, let’s say big, about a little more than a ruble. I had to measure the resistance on the collector when I took apart the engine. And without Was this the point of sorting it out?! In general, what about the engine should also be judged only after measurements...

The gearbox looks intact... maybe it was knocked out due to dirt. In short, we need to look for the motor... I called a couple of companies - no, but in general there are motors. We have to go and pick it up.

Well, in general, engines can be sold in small stores. But of course, you need to select them based on the facts. Since Makita ones can also fit Bosch, etc.

How to repair a screwdriver/sparks and stinks.

It’s also possible that you buy a new engine, install it on the old gearbox, and voila, the new engine starts smoking. There may be a problem in the gearbox, and it’s hard for the engine to turn the gears, so the load is huge, it’s just like a drill gets stuck in the part you’re drilling, and you keep pressing the button until the engine starts smoking.

The gearbox was rebuilt and lubricated - it spins normally.

Did you try to connect the engine at idle without a gearbox, does it smoke?

The windings of the motor most likely need to be changed, I had a problem with a hammer drill, everything was solved by replacing the rotor.

when turned on, smoke with a characteristic odor begins to come out of the ventilation grille (from the rear side)

who recently provided a link to a large selection of motors for screwdrivers?

a year ago I asked about the same thing and it’s also a mistake, in the end it still lives after a long period of inactivity, it can start to stink again, but then it works fine

PS I opened it and didn’t find anything burnt.

HZ, when the gearbox died, I tried to find a carcass or a burnt one on Avito, I didn’t get it and killed it, it’s lying around the computer. There are no inscriptions on the engine, but I looked at the photos - mine has brushes sticking out on the sides, and mine is 18 volts, yours is 14.

Some Makitas have poorly implemented protective shutdown and you can easily find by searching that Makita smokes. You can try unscrewing it and looking at the brushes and cleaning the commutator.

Well, or drive it at idle. Maybe it will cost

Brushless ones rule, when overloaded they beep and turn off without damage :-P

First of all, when the screwdriver or there is a burning smell, you need to turn it off. The reason for this is the operation of the screwdriver with a large overload. If it was turned off quickly, it may not have completely burned out and can be restored. The screwdriver must be disassembled, the electric motor removed and carefully inspected. If there is a strong burning smell, then most likely the screwdriver has burnt out completely. If the smell is barely noticeable, the motor windings should be carefully inspected. You also need to inspect the engine manifold. If the winding insulation has only darkened or the insulation is broken at a point, then the electric motor can still be saved. To do this, you can soak the pinpoint insulation breach with nail polish. If the winding darkens, but there is no insulation failure, you can turn on the screwdriver for a short time without load. It is quite possible that it will to work , but you need to handle it with care. It is better to check the winding with a multimeter. I have had to revive electric motors in this way more than once.

If your screwdriver starts smoking and a characteristic smell appears, then:

• Disable the tool. It should not be running and should not be connected to the network.
• Make sure that the smoke does not come from the workpiece that you are processing with a screwdriver. For example, if you used the drill function and worked at high speed, the wood could heat up and burn.
• If possible, disassemble the disconnected screwdriver, getting to its electrical components (the motor, in particular).
• Carefully inspect everything that touches the winding. If it is burned locally, if it is barely noticeable and has a tiny area, try to restore the varnished layer by saturating the problem area with varnish. It's easier if it's on the stator. But burning the varnish threatens breakdown.
• Carefully remove dust and sawdust.
• If the breakdown is eliminated in this way and there is no burning smell the next time you turn it on, then continue to use the screwdriver with a reduced load, lubricating it. The load singes the varnish. Low voltage may allow it to work.
• In case of other violations (armature, brushes, bearings, wire or inability to diagnose), appropriate repairs are necessary, which can be carried out by an experienced person, if not a qualified one. If repair is impossible, select a more powerful screwdriver.

Well, what can we do? We’ll repair it if you didn’t go to the service center but came to us for advice. It is clear that for this you need to know at least the basics of electrical engineering (terms and concepts)

In general, cordless screwdrivers (screwdrivers) rarely start to smoke, compared to a corded tool powered from a 230-volt network. This is due to both low voltage and lower power (speed). But for both of them, the main sources of smoke, judging from my experience, can be -

1 – eaten brushes (a lot of sparks are visible in the ventilation holes);

2 – turn-to-turn short circuit of the stator winding (smoke also comes from the vents, but the collector does not spark much);

3 – malfunction of the on/off button (the button gets hot, smells, a crackling noise is heard when turned on);

4 - extremely unfavorable operating conditions - dirt, dust, foreign particles in the engine (smoke, noise, ventilation holes are clogged. This often happens during large-scale repairs - chipping, etc.)

Identify the source of the smoke and odor and begin repairs.

• The simplest thing is if the brushes are burnt out. We just replace them with new ones, preferably original ones. It happens that the brushes wear out to the point that the copper contact wire pressed into the graphite begins to rustle along the commutator - sparks like from a sparkler, a burning smell and smoke. New brushes will initially spark slightly more than usual until they reach a radius equal to the diameter of the commutator.
• If the winding is broken, then little will help except rewind, even filling it with varnish. It's better to change it right away. And the efforts to possibly resuscitate a locked engine are not worth it; a new engine, even for Makita and Bosch, costs no more than 1,000 rubles. And Interskolovskie or Prorabovskie for 300-400 rubles.
• Very often, heating, an unpleasant odor and even smoke comes from the plastic of the power button. It contains contacts, and from frequent on/off. They, of course, spark and heat up, the heat is transferred to the plastic case, which smells and smokes. My advice in this case is to change the entire button (clean and bend the contacts - like a poultice for the dead)
• Will have to clean and rinse. Just don’t follow the advice of smart people who say that you can wash a cordless screwdriver by lowering the commutator assembly into white spirit and run it for a few minutes - this is nonsense. To clean it you will need to disassemble the shurik. Usually these are 6-8 bolts on one side of the body. Some bolts may be under plugs, be careful. Unsolder and remove the motor. So it will need to be washed separately. Clean the grooves between the collector slats. Dry thoroughly! After drying, check it for an interturn short circuit (short circuit) while it is not connected to the switch (if you do this directly in the shura, you can easily burn the switch’s working transistor. At least one wire from the motor must be unsoldered!). The engine is checked by simply connecting it to the original battery of the screwdriver. If the engine runs and does not smoke, then everything is fine with it. If it smokes or at least even smells stronger than usual, change the engine; if it is not closed, it is already scorched. And a “fried” engine very quickly kills the battery, which usually costs five times more than the same engine.

Dmitry Podi Something burned during the short circuits. It was necessary to immediately change the wire to a rubber one, but the original one was clear that it was being thrown away.

Ilnur Oh, how I love all these fairy tales. ) The previous (black and green) model of the SPEC 400 corded screwdriver has been working for me for years, I use it intensively and I’m just happy. Everything turns! With it I completely forgot about my favorite Bosch drill: it has two speeds, awesome torque, two in one is much more convenient. Of the shortcomings. Only the cord is short, but this can be fixed with an extension cord. And last August, the neighbors’ jamshuts “worked”, they asked for an indestructible Sparky 230 angle grinder with a new circle like “owner, we just need to cut off the channel”, after five minutes the circle was in shreds, and the channel was chewed like a rat. They explained that I had a bad instrument. :)))

Evgeniy Evgeniy You simply did not use excellent screwdrivers with dynamic braking. I have almost the same BSE as you, an older version. pure motor with handle and light, for rough work with screwing screw heads. The force adjustment spring breaks in the cartridge. manufacturers rejectors. But in so many years it was possible to make a super screwdriver ! Oh, I liked the backlight and the ball joint of the power cord. very necessary things, although not the main ones.

Evgeniy Evgeniy Without a heavy load, speed 2 got a little hot, but on speed 1 everything was fine, which is why I took the two-speed one. It's a pity that the black plastic smells strongly, but it will probably air out. I will soon replace the wire with a rubber one. The warranty will still expire until it is needed at the construction site.

Why does a screwdriver spark?

Of considerable importance is the service life of the tool, which shows sparking that exceeds the norm. The fact that a new screwdriver sparks during operation is completely normal for any brushed motor. Sparks occur as a result of a constant break in the connection between the electrically conductive brush and the commutator contacts, separated from each other by a technological gap. In this case, slightly increased sparking disappears after grinding in the brushes during the first 10-15 minutes of tool operation.

It is important to find out why the brushes of an Interskol, Makita, etc. screwdriver, which have worked for many days, months or even years, spark strongly. This can happen for the following reasons:

• contamination of the contact pads of the collector with carbon deposits formed when the engine operates under heavy loads. To remove carbon deposits, you will need to carefully clean the collector with the finest sandpaper;
• accumulation of graphite dust in the gaps between the commutator lamellas, which occurs mainly when the brushes are incorrectly positioned due to backlash. Dust is carefully removed mechanically using a sharp object;
• If the screwdriver sparks inside and smokes at the same time, there is a high probability of an interturn short circuit in the armature, which can be accurately identified by a special device that induces an alternating magnetic field. In this case, only rewinding the winding or completely replacing the armature (motor) will help.

The reason why the screwdriver sparks when stopping is that the model has an electric brake. It helps the shaft stop almost instantly, and the appearance of sparks is considered normal.

You can always make sure that the tool is in good working order and get prompt and inexpensive repairs in the “Successful Equipment Service” workshops!

Brushes spark on a screwdriver

What do you need? Your drill sparks on the brushes and you don’t know what to do under these circumstances. This article will tell you why this happens, whether it needs to be fixed, and if so, how.

It should be immediately noted that the presence of the indicated sparking during operation is a completely acceptable phenomenon. True, only if the sparks are small and there are not so many of them. When they directly fall out, this may indicate a malfunction.

On the contrary, your drill is no longer under warranty, that is, the option is to try and fix it, which remains for our client to do himself.

But first, let’s describe the prerequisites for this phenomenon.

Sparks, including on a working engine, occur due to mechanical action between the brushes and the commutator. Brush

, moving along the collector from one of its contacts to the other, alternately forms and breaks connections with all of them. Next, remember what happens if you unplug any working electrical appliance from the socket - usually at this moment a spark jumps between the plug and the socket. If the passage is carried out by a brush motor, this is the same phenomenon.

Therefore, a small spark even on a working electric motor is acceptable, since connections and breaks appear here all the time.

Now let's move on to strong sparking. It appears mainly for the following reasons:

1. contamination of collector contacts with carbon deposits
2. graphite dust getting between the collector contacts
3. interturn short circuit in the armature winding

Let's go through each point separately.

1) Carbon deposits come out after the engine overheats. The presence of carbon deposits leads to even greater friction, which leads to even more rapid overheating and even greater formation of carbon deposits. Which leads to breakdown in a short time.

Why do the brushes in a screwdriver motor spark?

Excessive sparking occurs here for the reason that carbon deposits form additional resistance when the spark at break comes out larger and stronger.

The carbon deposits should be removed immediately.

This is done with zero sandpaper. In other words, you need to remove the collector along with the armature and carefully clean it. It is better to carry out cleaning on a lathe so as not to disturb the correctness of the circle. But, usually, there is no such ability, so many people make do with manual stripping. The main thing with all this is not to overdo it.

5) During operation of the drill, the brushes wear out, causing graphite dust to appear. It can simply accumulate between the contacts of the collector and lead to short circuits in them, because it is a conductor of electricity and has its own resistance. Because of this, the current is distributed unevenly, which leads to the appearance of large sparks here and there.

With a working drill, abrasion occurs quite slowly, so graphite dust practically does not accumulate. Accordingly, its accumulation indicates that the brushes are in the wrong position during operation. This usually happens when their value is not tightly locked in its own groove, but, on the contrary, has a certain free movement.

This often happens when replacing brushes, when they are not selected in a very suitable size. Therefore, when substituting, you should pay close attention to this point.

Repair of such a malfunction is carried out by removing dust with any pointed equipment and changing brushes to more suitable ones in size.

3) If an interturn short circuit occurs in the armature, the current flows in a greater value to some contacts and in a minimum to others. Because of this, in some places a current of greater value than necessary passes through, under the influence of which large sparks are formed.

It is necessary to identify such a short circuit when the previous two steps did not produce any particular effect. It is done using a special device that produces an alternating magnetic field. When an armature is placed in this field, it begins to rattle because induced currents arise in the personal computer.

Some people make such a device themselves from a power transformer, in the core of which a cutout is made where the armature is placed.

If the reason turns out to be an interturn short circuit, then it is necessary to rewind the winding or completely change the armature.

These are the prerequisites for the appearance of excess sparking on the drill brushes. Remember, if you don’t do anything about it, then, basically, the engine will break down very soon. Don’t be lazy and follow the tips indicated in the text of the article.

Possible reasons

In working condition, the brushes move and interact with each contact of the commutator. When working, a connection between them is alternately created and broken. At the moment of rupture, you can observe how the screwdriver sparks. Minor sparking is considered normal.

You should pay attention in a situation where strong sparks fly out in a sheaf. There may be several reasons:

• carbon deposits have formed on the collector contacts;
• graphite dust from the brushes ended up between the contacts;
• short circuit in the armature on the windings.

Now we need to find the source of the phenomenon and correct it.

Carbon deposits are the result of engine overheating. This circumstance leads to increased friction and overheating.

The vulnerability of the commutator motor lies in the fact that the brushes wear out when rubbing against the copper plates of the commutator, and dust is released, which gets through the ventilation holes onto an important technical unit.

When shorted, the screwdriver sparks inside and smokes, and an odor may appear. Knowing the sources of spark formation, you need to begin eliminating them.
