Abstract:
1. A stator coil, comprising: a plurality of segments received in a plurality of slots of a stator core and serially connected with each other to construct one turn in a phase coil in M (integer greater than or equal to 3) phase coils, said slots being arranged along a circumferential direction of said stator core, and each slot having an even number of receiving positions disposed along a radial direction of said stator core; each of said segments comprising: a pair of slot conductor portions which are, respectively, received in two receiving positions of a pair of slots distant by a prescribed pitch in said circumferential direction of said stator core; a head portion which is projected toward an end of said stator core; and a pair of projected end portions each of which is projected from another end of said stator core; said head portion comprising: a U-shaped head tip portion; and a pair of head oblique portions each of which is stretched obliquely along the circumferential and axial directions of said stator core; said pair of projected end portions comprising: a pair of end oblique portions each of which stretches obliquely along the circumferential and axial directions of said stator core; and a pair of end tip portions each of which is formed at a tip of said corresponding end oblique portion and is joined with an end tip of said other end tip portion; wherein each of said head oblique portions or each of said end oblique portions is made circular-arch-shaped around an axis of said stator core.
