CONTROL APPARATUS, control method AND BRUSHLESS MOTOR

The invention provides a control apparatus, a control method and a brushless motor. The 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. 本发明提供控制装置、控制方法以及无刷电机。控制装置具有控制部，所述控制部通过矢量控制来控制施加到无刷电机的多个相的各相的电压、电流，所述矢量控制在对转子的旋转进行控制时，利用以q轴电流为主的旋转控制来进行，在接收到停止的指令信号时，利用以d轴电流为主的励磁固定控
