The motor is equipped with a high-sensitivity comprehensive protection circuit
Source: InternetPublisher:酷到被通缉 Keywords: Protection circuit motor relay Updated: 2020/06/23
Working principle of the circuit: According to the actual situation that the winding will heat up first before the motor burns out, a small thermal relay
is installed on each phase winding of the motor , and the two
thermal relays are connected in series. As long as the winding temperature reaches the thermal relay Curie point temperature
(95℃), the thermal relay will automatically disconnect for protection.
The winding temperature of the motor during normal operation is much lower than the starting temperature of the thermal relay , so major electrical accidents can be avoided
