NettetThe stator RTD sensor is a rectangular, flat, laminated sensor commonly called “Stator Sticks” because they are inserted between the coils in the stator of a motor. These averaging type sensors are used in electric motors and generators for continuous sensing of the temperature and provide for consistent thermal monitoring without false alarms. Nettetfrom a Class F insulated motor whose total allowable running temperature is 155°C results in a skin temperature of 125°C (257°F); therefore if your T-frame motor is too hot to the touch, it does not necessarily mean that it is operating improperly. Today’s motors are designed to run hotter than our human hands can tolerate.
