Tips: How to Maintain Explosion Proof Motor?

1. When inspecting the stator core, pay attention to whether the stator core is compressed. If the core is found to be loose, a wedge made of an insulating plate should be driven into the slack; when inspecting the slot of the stator coil, pay attention to the coil Notch section. Loose and discolored slot wedges must be dealt with.

2. When checking the end of the coil, check the insulation for damage and the condition of the paint film. Pay attention to the end fixation. If there is a loose end at the end, a spacer should be added, or a new spacer and tie wire should be used to fasten the end; the insulation paint film at the end of the coil should be cracked or peeled off, and should be re-strengthened insulation.

3. Note that no debris should be left in the motor. Use a megger to measure the insulation resistance of the coil.

4. When the rotor is overhauled, blow the rotor clean with compressed air; check the welding condition of the coil, wire rod and joint; check and deal with the loose and damaged wedge; check the fan itself and its fixing condition; check the condition of the slip ring, The unevenness of the slip ring surface should not exceed 0.5mm; check the insulation of the rotor coil and the tie wires, and strengthen the insulation if necessary.
