ABSTRACT:
A permanent magnet embedded type concentrated winding motor generator, wherein of the mechanically and electrically independent first and second winding groups (4, 5), the plurality of first teeth (2) wound with the first winding groups (4) are divided into three groups (I, II, III) for example, and the winding directions of the windings of adjacent first teeth (2) within the same group (I, II, III) are opposite. Furthermore, one second tooth (3) wound with a second winding group (5) with a different winding specification from the first winding groups (4) is provided between each of the groups (I, II, III). Accordingly, the relative sizes of the generated voltages in the first winding groups (4) and the second winding groups (5) differ each other, allowing the realization of a compact and low cost construction capable of charging two different electric potentials from a single unit, which also enables a reduction in distortion of the waveform of the counter electromotive force, a reduction in iron loss, and an improvement in the efficiency of the motor, and enables the efficient charging of power sources with two different electric potentials.
