发明名称 Excessive temperature protection circuit for a three phase motor
摘要 The circuit has an angle encoder for determining the rotor position and a temperature sensor with a switch (6) for interrupting the current supply to the angle encoder. The temperature sensor is a positive temperature coefficient resistor and the angle encoder is a Hall sensor with pull-up resistances (7) between the current supply to the Hall sensor circuit (5) and the sensor (4) outputs.
