The function of the motor protector is to provide comprehensive protection and control of the motor. Overcurrent, undercurrent, phase failure, stall, short circuit, overvoltage, undervoltage, leakage current, three-phase unbalance, overheating, grounding, bearing wear, etc. occur in the motor. When the stator and rotor are eccentric, the aging of the winding can be alarmed or protected and controlled
