Title: ROTARY ELECTRIC MACHINE
Abstract:
A rotary electric machine equipped with an armature and a rotor. The armature has: a stator core equipped with a plurality of magnetic teeth; and an armature winding comprising a plurality of multi-phase winding groups wound on the teeth and accommodated in slots between adjacent teeth. The rotor is arranged with respect to the armature so as to have a magnetic gap therebetween, and is provided so as to be capable of rotating around a rotary shaft. The rotor is equipped with a rotor core, and permanent magnets are embedded in the interior of the rotor core. The rotor core has a skewed-stage structure comprising two or more stages in the axial direction, and when viewed along the direction of the rotational axis, magnets in different stages and having different polarities are arranged so as not to overlap one another in the circumferential direction.
