How to check and clean the stator and rotor?
After the motor is disassembled and disassembled, the following checks and cleanings should be performed on the stator and rotor.
1 Clean the dust on the rotor and the rotor with compressed air or leather tiger.
2 Oil tower and dirt on the coil, wipe with a clean cloth, alcohol or carbon tetrachloride.
3 Clean the core, coil and commutator, etc., do not use metal tools to prevent damage to the insulation. Use a clean brush or a soft rag.
4 Check whether the iron core lamination is tight, whether there are defects such as burrs and chamfers; whether the clamping bolts are symmetrically pressed, whether the chains, pins, etc. are loose; whether there is any debris in the ventilation ditch and the welding of the ventilation sheets is firm.
5 Check the coil insulation for bubbles, peeling and damage; whether the coil wire, wedge and pad are complete, fastened, loose or swayed, or the wedge protrudes from the core.
6 Check whether the magnetic pole and the coil are fixed firmly, whether the insulation of the insulating bolt is good, whether the compensation coil of the extreme palm is tight and whether the wiring is bent or short-circuited.
7 Check whether the balance block on the rotor is firm, with or without displacement and falling off.
8 Check whether the armature winding binding wire is firm, and whether the head cover, the lifting piece and the lead wire are damaged or poorly welded, and there is no conductive foreign matter between the slits.
9 Check the cage rotor copper strip (aluminum strip) for cracks, whether the welding with the end ring is firm, whether there are cracks or looseness, and whether the leads are damaged or broken.
In the above inspection, if problems are found, corresponding measures should be taken to repair them, and the damage should be replaced in time.
