Abstract
A rotating electric machine having a fraction slot configuration in which the number of slots per pole per phase is not an integer includes: a stator that includes a stator core provided with a plurality of slots, and a stator winding having a plurality of coil sides accommodated in the plurality of slots and a plurality of coil ends connecting the same side end parts of the plurality of coil sides to each other; and a movable element that is supported to be movable with respect to the stator, and includes a movable element core, and a plurality of movable element magnetic poles provided in the movable element core. The stator winding includes a plurality of basic coils in which the magnitude of magnetomotive force generated by the plurality of coil sides forming the one-phase band is uniform in each of the plurality of movable element magnetic poles.
