Last time, we said that motor overload is related to many factors, among which improper selection can also causeThree-phase asynchronous motorToday, Senli Motor Xiaobian will share with you about the overload caused by too low end voltage and non-compliance with the stator connection.
Low end voltage means,Three-phase squirrel-cage asynchronous motorThe voltage measured at the stator lead end during starting or full load operation, rather than the voltage when unloaded. So if the load is a certain case, if the voltage is reduced, then the current will increase, which will cause the temperature is too high; If the phenomenon is more serious, too low voltage will cause the motor to stop or run at a low speed, and the current will surge leading to burnout.
The stator connection does not meet the requirements, that is, the wiring error or not according to the specified wiring method, the two common wiring methods of three-phase asynchronous motors are star and triangle, if the star type380VThe motor is connected into a triangle, then the no-load current will increase, and the electric machine will burn out instantly; If it's a triangle connection380VConnected to the star type, the load will run at a low speed because of low voltage, which will also cause the current to be too large and burn the motor.
