  • Rotary electric machine and method of manufacturing the same
    Patent number: 6140735
    Abstract: In a multi-phase rotary electric machine, each of phase windings is composed of a pair of semi-phase-windings having a starting end portion, a plurality of series-connected wave-coil units, and a connecting end. Each of the wave-coil units is composed of a pair of in-slot-portions and a pair of crossing portions. One of the pair of semi-phase-windings is disposed on top of the other in the radial direction in the same slots, thereby forming a pair of coils each the magnetic pole. Each of the crossing portions of one of the pair of semi-phase-windings has a flat U-shaped-folded-portion disposed on top of one of the crossing portion of the other in the radial direction so that the U-shaped-folded-portions of the pair of semi-phase-winding can be aligned in the radial direction.
