Abstract
A control circuit and method for controlling a switched reluctance motor are provided. The control circuit includes a tone wheel and a Hall effect sensor for generating a position feedback signal indicative of the position of the motor. The control circuit also includes a sensing resistor for generating a current feedback signal indicative of a level of current in a phase coil of the motor. Finally, the control circuit includes first and second switches connected to opposite ends of the phase coil for controlling the level of current in the phase coil responsive to the position feedback signal and the current feedback signal.
