Abstract: A control apparatus includes a controller that controls, by vector control, voltages and currents to be supplied to plural phases of a brushless motor. The vector control is performed through rotation control using a q-axis current predominantly to control rotation of a rotor, and field fixing control using a d-axis current predominantly in response to reception of a stop command signal. The controller controls the brushless motor with reduced influence of a dead time, in which a high-side switching element and a low-side switching element of each of plural half-bridge circuits are simultaneously set to OFF. The plural half-bridge circuits are provided in association with the plural phases of the brushless motor and are configured to supply the voltages and the currents to the respective phases. The influence of the dead time is reduced through the field fixing control.
