Abstract
A motor control device includes: a voltage boosting circuit that boosts a power source voltage supplied from an outside; a condenser that smooths a voltage output by the voltage boosting circuit; an inverter circuit that generates a drive voltage of a motor by switching a voltage output by the voltage boosting circuit and smoothed by the condenser; and a control part that causes the voltage boosting circuit to bypass and causes the power source voltage to be supplied to the inverter circuit, and a distance between the voltage boosting circuit and the inverter circuit is a distance with which a parasitic inductance is equal to or less than a predetermined value.
