Drive device for precisely controlling the rotation speed, torque, and rotation direction of DC motors. Used for positioning mechanisms in manufacturing equipment, conveyor systems, feed axes of machine tools, and actuator drives in automation equipment. Features built-in PWM control, H-bridge circuits, and current control functions, including encoder feedback compatible models and brushless DC motor dedicated types. Distinguished from DC motor bodies, this classification specializes in drive control equipment such as control circuit boards, driver ICs, and motor controller units.
