Abstract
According to one embodiment, a driving device includes a power converter, a voltage controller and a phase adjuster. The phase adjuster is configured to execute a first phase control process of receiving first information relating to a relationship between a phase of a motor current flowing through the motor and a rotational position of the motor, and adjusting the phase of the driving voltage, based on the first information. The phase adjuster is configured to execute a second phase control process of receiving second information relating to a magnitude of the motor current and third information relating to a rotational speed of the motor, and adjusting the phase of the driving voltage, based on the second information and the third information.
