Abstract
Provided is a motor control device that includes a controller outputting a PWM control signal for controlling a multiphase electric motor, a driving signal generator generating a switching element driving signal for driving the multiphase electric motor according to the PWM control signal output from the controller, and a bridge circuit configured of a plurality of semiconductor switching elements switching a current flowing through the multiphase electric motor according to the switching element driving signal generated by the driving signal generator. The controller is provided on a first board. The driving signal generator and the bridge circuit are provided on a second board and are connected by wiring provided on the second board. The first board and the second board are connected by a predetermined inter-board connecting line. The controller outputs the PWM control signal to the driving signal generator through the predetermined inter-board connecting line.
