Motor winding protection
NettetWhen the motor is overloaded and the winding temperature rises close to the limit value, the bimetallic sheet with one contact is heated and bent, causing the contacts to open and cut off the circuit. The thermal protector is a thermal dynamic overload protection relay used on the motor body. NettetPTCs are used to protect the motor winding and trip when the maximum permissible winding temperature is reached. The PTC (Positive Temperature Coefficient) is a …
