[0002] A motor controller is an integrated circuit that actively controls a motor to operate in a set direction, speed, angle, and response time. It can be divided into DC motor controllers and AC motor controllers according to the different current forms. Motor controllers are widely used in a wide range of fields, including automobiles, home appliances, industrial control, and military.
