A motor controller is an integrated circuit that actively controls a motor to operate according to set directions, speeds, angles, and response times. In electric vehicles, the motor controller converts electrical energy from the battery into electrical energy to drive the motor, controlling the vehicle's starting, running, forward and reverse speeds, and other driving states, or recovering braking energy.
It can be applied to small motors such as DC motors, brushless DC motors, and stepper motors. More complex motor controllers can precisely control the motor's speed and torque. Intelligent controllers utilize microprocessors to control power components, monitor motor load, and match torque to load to improve energy efficiency.
