Abstract
In a permanent magnet-embedded, concentrated winding motor, plurality of stator teeth are divided into, for example, three groups that include a plurality of adjacent stator teeth having coils wound around and that are provided with voltage in phase that are set as one group. Coils are wound in opposite directions around adjacent stator teeth in the same group, while the relation between the angle h of a slot opening between adjacent stator teeth of the same group and the angle H of a slot opening formed between adjacent stator teeth of different groups satisfies h
