摘要： An object is to provide a driving device capable of detecting a current of a motor without any trouble even in a low rotation speed/low load state to continue a sensor-less vector control, in a case where the motor is driven by the sensor-less vector control, and the driving device comprises: a main inverter circuit for applying a pseudo alternating voltage to a permanent magnet type motor M to drive the motor; a current sensor 6 which detects the current flowing through the motor; and a control circuit which controls the main inverter circuit. Based on an output of the current sensor, the control circuit separates the current flowing through the motor into a torque current component and a field current component to control commutation of the main inverter circuit by the sensor-less vector control. In a case where the motor is operated in a predetermined low rotation speed region and/or the motor is in a predetermined low load state, the field current component is passed in such a direction as to weaken a magnetic flux of a permanent magnet.
