When using micro electric hoists, there may be some faults. What faults should be handled? Based on years of production and research experience, Hebei Fanggong has summarized the troubleshooting of micro electric hoists, mainly in the following situations:

　　1. After starting, the motor does not rotate and cannot lift heavy objects. (1) Excessive overloading. Overloading is prohibited. (2) The voltage is more than 10% lower than the rated voltage. At this point, it is necessary to wait for the voltage to return to normal. (3) Is there a malfunction in the electrical appliance, with a broken wire or poor contact??. At this point, it is necessary to inspect the electrical appliances and wiring (4). The brake wheel and rear end cover are rusted and jammed, and the brake wheel cannot be detached. It is necessary to remove the brake wheel and clean the rusted surface. (5) Motor sweeping??. Quickly cut off the main power supply for disassembly and maintenance or replace the AC contactor.

　　2. The starter cannot be opened during startup. (1) The brake friction surface clearance is too small. It is necessary to adjust the locking nut to increase the gap (2). The brake wheel and rear end cover are rusted and jammed, and the brake wheel cannot be detached??. Just remove the brake wheel and clean the rusted surface.

　　3. The temperature rise of the motor is too high. (1) Overload usage??, Overloading is not allowed. (2) Homework is too frequent??. Operate according to the requirements of 25% and 120 times/h. (3) The brake clearance is too small, and the brake ring is not fully disengaged during operation, which is equivalent to an additional load. Just readjust the gap.

　　4. When closing the magnetic starter, the starter experiences severe sparks and the contact is welded. (1) The contact surface of the contact point is burnt out. Or caused by frequent and prolonged closure with strong starting current. Need for maintenance or replacement 5. Cannot stop after starting, or does not stop even when reaching the limit position??. (1) Fusion welding of AC contactor contacts. Quickly cut off the main power supply for disassembly and maintenance or replace the AC contactor??. (2) The limiter is malfunctioning. Quickly cut off the main power supply for disassembly and maintenance or replace the AC contactor??. For more troubleshooting of micro electric hoists, continue to follow Beijing Lingying.
