ABSTRACT:
A tail side coil end includes a plurality of tail conductor pairs sequentially disposed with predetermined radial gaps. The radial gaps between the conductor pairs are widened in the vicinity of their tail joint portions compared with those in the vicinity of the end surface of a stator core. This arrangement effectively prevents adjacent tail joint portions or adjacent slanting portions from undesirably contacting with each other, thereby adequately maintaining electric insulation between the tail conductor pairs and also improving the space factor of the slot.
