Provided is a rotary electrical machine, which is reduced in size of a motor through use of reluctance torque being a feature of an IPM motor, and in which, in driving in times other than a rated time, a current phase angle is shifted from an angle at which a total torque is maximized so that an increase in torque ripple is suppressed even when the current phase angle changes, to thereby provide characteristics of small size, high output, and low torque ripple.

A rotary electric machine is equipped with a stator and a rotor. The rotor has a d-axis magnetic circuit that is produced by a magnetomotive force of a field winding, and magnet magnetic circuits that are produced by a magnetic force of permanent magnets. The d-axis magnetic circuit and a q-axis magnetic circuit have at least a part thereof that is common to both. The permeance of the d-axis magnetic circuit is smaller than the permeance of the q-axis magnetic circuit, when a load is being applied to the rotor. A control apparatus of the rotary electric machine has a switching circuit that controls the field current in the field winding, and a control section that makes the switching frequency of the switching circuit become higher when the field current is above a threshold value than when the field current is less than or equal to the threshold value.

The linear motion mechanism and the electric motor are arranged in the axial direction with a rotary input-output shaft of the linear motion mechanism interposed therebetween. In the electric motor, orientation of a magnetic pole generating interlinkage flux is parallel with a rotation shaft of the motor. The linear motion mechanism has a thrust bearing for retaining a reaction force against a load in the axial direction in association with linear motion of the linear motion part. The control unit has a thrust force applying section for applying a thrust force such that a force acting in the axial direction of the rotary input-output shaft due to interlinkage flux between the stator and the rotor causes generation of a force, in the axial direction, acting on the thrust bearing.
