Abstract
An armature includes an armature winding of multiple phases having phase windings, for each phase, that includes a plurality of partial windings, and a base member that includes a circular cylindrical back yoke. The partial winding includes a pair of intermediate conductor portions and crossover portions that connect the intermediate conductor portions in an annular shape. A conductor is wound in multiple layers in the intermediate conductor portions and the crossover portions. An interference prevention portion extends in a radial direction. The intermediate conductor portions are arrayed in a predetermined order in the circumferential direction, by one of the intermediate conductor portions of a first phase being arranged between the intermediate conductor portions of the partial winding of a second phase. The partial windings are assembled to the back yoke in a state in which an insulation layer is interposed between the intermediate conductor portion and the back yoke.
