发明名称 STATOR FOR ROTATING ELECTRIC MACHINE
摘要 A stator includes an annular stator core having slots arranged in a circumferential direction thereof and a stator coil comprised of phase windings. Each of the phase windings includes in-slot portions, each of which is received in one of the slots of the stator core, and turn portions each of winch is located outside the slots to connect one pair of the in-slot portions. Each of the turn portions includes an apex part that is furthest in the turn portion from an axial end face of the stator core and extends in the circumferential direction of the stator core. There are circumferentially-adjacent pairs of the turn portions over the entire circumferential range of the stator coil. For each of the circumferentially-adjacent pairs of the turn portions, the apex parts of the circumferentially-adjacent pair of the turn portions overlap each other in an axial direction of the stator core.

主权项 1. A stator for a rotating electric machine, the stator comprising: an annular stator core having a plurality of slots arranged in a circumferential direction of the stator core; and a stator coil comprised of a plurality of phase windings that are mounted on the stator core so as to be different in electrical phase from each other, each of the phase windings having a substantially rectangular cross-sectional shape and an insulating coat formed on its outer surface, each of the phase windings including a plurality of in-slot portions and a plurality of turn portions, each of the in-slot portions being received in one of the slots of the stator core, each of the turn portions being located outside the slots of the stator core to connect one pair of the in-slot portions respectively received in two different ones of the slots, wherein each of the turn portions of the phase windings of the stator coil includes an apex part that is furthest in the turn portion from an axial end face of the stator core and extends in the circumferential direction of the stator core, there are circumferentially-adjacent pairs of the turn portions over an entire circumferential range of the stator coil, and for each of the circumferentially-adjacent pairs of the turn portions, the apex parts of the circumferentially-adjacent pair of the turn portions overlap each other in an axial direction of the stator core.
