Abstract
A controller which controls an electric motor in such a manner that a rotational speed detected in a motor rotational speed detecting module 29 becomes a target rotational speed set in a target rotational speed setting module 37 controls, when a deviation between the rotational speed and the target rotational speed is large, a normally open solenoid valve in such a manner that a controlled variable of the normally open solenoid valve becomes smaller when the deviation is small.
