The motor nameplate is marked with rated current, and it is not allowed to exceed the rated current in use, otherwise it will burn the equipment. thereforeThree-phase asynchronous motor manufacturersWill do current protection module, when the current exceeds the set current, the equipment automatically power off, to protect the equipment.
Three-phase asynchronous motorThe working principle is based on the interaction between the stator rotating magnetic field and the rotor current, that is, the interaction between the synthetic magnetic field generated by the three-phase current in the stator winding and the current in the rotor winding.
Asynchronous motorThe overcurrent protection refers toThree-phase asynchronous motorThe working current exceeds its rated value, if maintained for a long time, it will cause the motor to overheat and damage the motor, so it is necessary to take protective measures for the asynchronous motor. When the overcurrent, the current is still the normal path flow, but the value will be smaller than the short-circuit current value; Overcurrent is usually caused by excessive load or incorrect start. Therefore, in order to avoid affecting the normal operation of the asynchronous motor, the overcurrent protection action value is slightly greater than the normal starting current.
Three-phase asynchronous motorOvercurrent protection also requires that the protection device can act instantaneously, and overcurrent protection generally uses overcurrent relays.
