Abstract:
An armature coil includes a first portion, a second winding portion, a first winding end, a second winding end, and a crossover portion, and is continuously wound. The first winding portion is concentratedly wound in a counterclockwise winding direction with respect to a direction obtained in viewing a second end portion from a first end portion of a tooth, as it passes from the first winding end to the crossover portion. The second winding portion is concentratedly wound in a clockwise winding direction with respect to a direction obtained in viewing a second end portion from a first end portion of the tooth, as it passes from the crossover portion to the second winding end.
