  • DC motor brush filter circuit
    Patent number: 6930457
    Abstract: The present invention provides a motor control circuit including a motor with a motor winding and a brush, a battery, a relay, and a ground return circuit. The battery is for energizing the motor. The relay selectively provides connection between the battery and the motor. A ground return circuit is in communication with the brush. The ground return circuit creates a path from the brush through the relay to an electrical ground.
    Type: Grant

  • DC motor having a braking circuit
    Patent number: 6876163
    Abstract: A circuit for controlling a motor's operation is disclosed. The circuit includes a relay and a motor braking circuit portion. The relay selectively interconnects a voltage source with one of a braking terminal and a motor terminal. The motor braking circuit portion has a motor brake switch connected on a first switch side to the motor terminal and a second switch side to the electrical ground. The brake switch is activated to brake the motor when the relay interconnects the voltage source with the braking terminal.
