Before the burned-out motor damage, its winding temperature rises high; in many occasions, motor is easily bilging, resulting in burned. The circuit is shown in Figure. It can prevent overheating influent accidents. RT is a positive temperature coefficient thermistor (PTC); M, N are plastic insulated wires which are closed and buried in the motor stator windings, and their heads are stripped, they are used for detecting the motor inlet.
