How does electric drill rotor stator friction generate heat?
If there is no friction at the beginning, please follow the following procedure:1. Two check the position of the bearing shell, if worn or damaged, such as, basic machine.2. No, please note that when friction occurs in the engine, there is no such phenomenon in the refrigerator. The rotor needs replacing.3. Check for loose wire problems.4. If the friction is not much, in front of three does not exist, please remove the rotor on the lathe turning rotor xigangpian cylindrical, unilateral within 0.4MM, but will not force the drill slightly.
This is because the stator and rotor at a certain point of the air gap is 0, commonly known as "sweep the chamber", the solution is to replace the bearings at both ends.
If the friction is not much, in front of three does not exist, please remove the rotor on the lathe turning rotor xigangpian cylindrical, unilateral within 0.4MM, but will not force the drill slightly.
If there is no friction at the beginning, the following procedure shall be taken:1. Two check the position of the bearing shell, if worn or damaged, such as, basic machine.2. No, please note that when friction occurs in the engine, there is no such phenomenon in the refrigerator. The rotor needs replacing.3. Check for loose wire problems.
