Abstract
To provide a motor controlling device that reduces heat generated by an armature and switching elements when an alternating motor is activated. A motor controlling device includes: an H bridge circuitthat has FETto FETthat connect and disconnect a high potential end HV and a low potential end GND of a direct-current power supply to and from an armature Lu; and an energization control unit for controlling the amount of energization of the armature Lu by the PWM control that involves changing the ratio, in a predetermined control cycle, between an energization control period, in which the FETand the FETare turned on and the FETand the FETare turned off, or the FETand the FETare turned on and the FETand the FETare turned off, and a non-energization control period, in which the FETand the FETare turned on and the FETand the FETare turned off, or the FETand the FETare turned on and the FETand the FETare turned off.
