The rotary motor is configured to generate a current based on a direction of rotation of the rotary motor. The rectifier circuit is configured to applying a damping force against the rotation at the rotary motor based on an impedance. The logic circuit changes the impedance of the rectifier circuit based on the direction of rotation of the rotary motor.
