On the basis of an energization phase signal being output from a rotational phase sensor and changing its output at every predetermined rotational phase corresponding to a stepwise change (increase or decrease) in rotational phase, a motor controller switches a phase current passing through the corresponding phase coil, and changes the magnitude of the phase current passing through the corresponding phase coil such that an actual motor torque detected by a torque sensor coincides with a target motor torque.
