路。[Claims for Utility Model Registration] A current detection circuit that detects the excitation current flowing through a motor coil, and an error amplifier that has circuit constants set according to the type of motor and outputs the difference between the current command value and the detected current value. In a power control circuit for a motor, the circuit includes a PWM circuit that generates a PWM signal based on the output of the error amplifier, and a bridge circuit that is configured by combining switching elements and that is driven by the PWM signal and causes a current to flow through the motor coil. . A power control circuit for a motor, characterized in that the current detection circuit, the insulation circuit, and the bridge circuit are configured as one module, and the circuit is controlled by interfacing with a PWM signal from a host controller.
