Background
Electric motors are widely used in various aspects of modern life to convert electric energy into mechanical energy. In the working process of the motor, the motor is often damaged or destroyed due to overhigh temperature rise caused by abnormal working state. Three-phase asynchronous motors can be generally classified into normal heat generation and abnormal heat generation. When the motor normally operates, stator and rotor winding loss, stator and rotor iron loss, stator and rotor transmission loss, stray loss and the like exist, the motor normally generates heat, and the motor generates heat stably after a period of time. The causes of abnormal heat generation are many, such as: overcurrent due to frequent start, overcurrent due to overload, phase current/voltage imbalance, insulation aging, poor heat dissipation, and the like.
