Abstract
A motor control module provides control of a plurality of different motor types, such as a 1-phase DC Brush motor, a 3-phase brushless DC motor, and a 2-phase step motor. The module includes a digital amplifier that is configurable to drive the plurality of different motor types. A motor control unit, coupled to the digital amplifier, controls a motor type driven by the digital amplifier via a command signal to the digital amplifier. The motor control unit also monitors status information about the motor control module, including status information about the digital amplifier. A motor coil interface is coupled to the digital amplifier and configured to connect with the plurality of different motor types.
