To provide an energizing control method which enables to suppress inrush current immediately after energizing a motor and securely operate the motor.
An actual current Ia which flows in the motor 31 and a designated current I3 which is preliminary set are compared. If the actual current Ia is larger than the designated current I3, the duty ratio of energizing duration and non-energizing one is made smaller by a designated ratio. If the actual current Ia is smaller than the designated current I3 and the duty ratio does not exceed 100% even when the duty ratio is made larger by the designated ratio, the duty ratio of energizing duration and non-energizing one to the motor 31 is made larger by the designated ratio. If the actual current Ia is smaller than the designated current I3 and the duty ratio exceed 100% when the duty ratio is made larger by the designated ratio, the motor 31 is always energized.
