ABSTRACT:
A motor driving circuit capable of driving a motor with a single circuit regardless of whether the motor used is a brush motor or a brushless motor. The circuit detects a speed error between actual speed and commanded speed of the motor and provides a speed error signal. An inversion circuit selectively inverts or non-inverts the speed error signal in response to the type of the motor and desired motor rotation direction. When a brushless motor is used, the non-inverted error signal is employed for controlling driving of the motor. When a brush motor is used, the inverted speed error signal is employed.
