  • Trigger circuit with blocking protection device for a collectorless DC motor
    Patent number: 5162710
    Abstract: The invention pertains to a control circuit for a collectorless DC motor where at least one power transistor (14, 16) is input-connected to each stator coil (2, 4) of the motor; said transistor is driven by at least one rotor position sensor, especially a Hall generator having commutation circuits to commute the motor current, and where a blocking protection device is provided to interrupt the motor current in an overload or blockage. The blocking protection device (26) has at least one semiconductor circuit (30) carrying the motor current which is switched through or blocked depending on its temperature.
