Abstract

Phase coils include a first phase coil and a second phase coil, the phase coils are configured by connecting together end portions of the coil terminals of the first phase coil and the second phase coil that extend outward from identical radial positions in the slots axially outside the stator core so as to be radially outside a coil end group, and the coil terminals of the first phase coils of the phase coils of three phases include joint coil portions that extend outward from the slots within a pitch of one magnetic pole, are then bent so as to extend in an identical circumferential direction, and are placed in close proximity to the end portions of the coil terminals of the second phase coils that are intended for connection therewith.
