You will rarely get smoke from the brushes on electric tools. Smoke is usually a result of either the armature or field coils getting hot enough to melt or burn the varnish insulation off the wire which results in a loss of or no power because of shorting in the windings. You'll have to replace whichever part burned the windings and find out what caused the problem or you'll burn the new part the same way the original burned.
replace the motor, but you might also want to look into buying a new one unless your batterys are in great shape. The motor sounds like it is burning up and therefore draining battery and smoking. Let me know if you need more assistance and if you give me the exact model number I will try and find the cost and motor number.
The motor has jammed and burned out. It is probably not worth trying to repair.
If it is still within the warranty period take it back for replacement under guarantee
Hello, I hate when this happens to my tools. This could be a number of issues. I would think that the transistor that controls the motor speed is shot or the motor itself is loading the transistor causing the smoke, or the brushes internally of the motor are worn and causing the overheating, hence smoke. Is the unit new or well used?

I hope this drill is still under warranty as the battery is in serious trouble. As long as the motor is turning, it should not be causing the battery to do this. Hope this helps!
the tool with the brake will throw some sparks when it creates the short to stop rotation, but the SMOKE is an indication of a burnt motor and yes you should be concerned. Do you smell a burning odor when running if so the motor will soon fail.
When an AC motor is stalled, very high currents pass through the motor windings and melt the insulation on the windings; the smoke was the result of the motor winding insulation being melted. This causes a reduction in motor torque and premature failure.
You should suggest that your neighbor buy you a new drill and he keep the one that he ruined.
Save the battery and charger and forget the drill. I blieve the motor woul cost you at least half price of new. Go to the dewalt replacement site to find out
You have burned out the drill motor, it is shorted, the battery smoked due to a direct short, one thing I don't understand why the thermal limiter didn't trip in battery pack, I would contact manufacturer and try to get hem to buy you a new drill.
