The operation of the electromagnetic brake is affected by mechanical failures and electrical failures. The main reason is that the probability of failure is relatively high when starting, and the second is when it is under load or idling. Among them, mechanical failures include:
(1) Own failure: Long-term operation of the electromagnetic brake causes its own windings to be overheated, oxidized, corroded and burned, and the system frequently fails during operation.
(2) Electrical aspect: Due to insufficient power input and output voltage of the electromagnetic brake rectifier module, the electromagnetic brake cannot be normally absorbed during operation, and the power lead is corroded and oxidized for a long time, causing grounding or short circuit overcurrent switch trip events. Electromagnetic brake rectifier module wiring terminals, lead wires are dirty, loose and overheated, causing the electromagnetic brake to not be released normally, it will wear the rotating shaft grinding disc, and even increase the motor current to cause an overload trip event.
(3) Auxiliary component problem: When the electromagnetic brake contacts the fixed bolt of the motor body for a long time, it will cause the bolts to wear, corrode, deform and vibrate in the running state, resulting in the loosening of the fixed bolt, the electromagnetic brake and the electromagnetic grinding plate are delayed or closed. The interlocking system cannot be operated normally due to the failure to pull in normally.
(4) Wear: Due to the large gap between the electromagnetic brake and the electromagnetic grinding plate, coupled with dust and water mist pollution, the electromagnetic force between the electromagnetic brake and the electromagnetic grinding plate is reduced, and the electromagnetic brake cannot be normal with the electromagnetic grinding plate when the electromagnetic brake is energized. It attracts and increases the degree of wear on the grinding plate of the motor shaft.
(5) Brake failure: insufficient braking force, brake arm cannot be opened, brake release action is slow, braking torque cannot be braked in time, brake failure, wheel temperature is too high, brake shoe smoke and other faults.
