Abstract
A composite torque rotating electric machine includes a stator having armature windings arranged at multiple positions in a circumferential direction, a rotor having a cylindrical core, first permanent magnets arranged on axes (d) and in the circumferential direction on the outer periphery of the rotor, second permanent magnets arranged on axes (d) on the inner periphery side of the rotor across from the permanent magnets on the outer circumference side, third permanent magnets on axes (q) and extending in the longitudinally and radially of the rotor, and air gaps on the outer periphery side of the third permanent magnets and intermediate in the circumferential direction of the first permanent magnets. The radial distance between the first and second magnets is greater than the circumferential distance between the first permanent magnets and the air gaps. A rectifier having multiple slits is disposed between the first permanent magnets and the air gaps.
