Composite torque rotating electric machine

A composite torque rotating electric machine comprising:

• a stator in which armature windings are arranged at plural teeth in the circumferential direction at regular intervals;
• and
• a rotor, arranged inside the stator, with a cylindrical iron core obtained by laminating magnetic steel sheets, wherein the rotor comprises:
• plural permanent magnets arranged in the circumferential direction on an outer periphery;
• air gap portions in the middle of the circumferential direction between the plural permanent magnets of the rotor;
• and
• slit portions on both sides of the circumferential direction of the permanent magnets between the permanent magnets and the air gap portions and comprising plural slits;
• wherein the slit portions are arranged such that central axes of at least two of the slit portions intersect at a point located at a further distance, in a radial direction from a center of the rotor, than the slit portions and are shortened in radial length in order from a d-axis toward a q-axis, and
• wherein the slit portion nearest to the d-axis is parallel to the q-axis, and the slit portion nearest to the q-axis is parallel to the d-axis.
