Motor Temperature Sensor

Motor Temperature Sensor

Description

Temperature of the motor largely influences the motor output. Hence, when the motor is overheated,
major components such as the IPM or stator coil may get damaged or affected. To prevent this, a
motor temperature sensor is embedded in the motor to control the motor torque according to its
temperature.
