Title: STATOR FOR ELECTRIC MACHINE
Abstract:
Disclosed is a stator for an electric machine. The stator is provided with a stator core, and first and second series of coils each molded into a predetermined shape. Each of the coils in the first series is provided with a pair of first coil ends which respectively protrude from both end faces of the stator core. Each of the first coil ends is provided with a pair of bent portions which extend outward in the radial direction of the stator, and a bridge portion which connects the bent portions. Each second coil end is provided with a pair of upright portions and a bridge portion which connects the upright portions. The bridge portions of the coils in the first series are disposed outside the bridge portions of the coils in the second series in the radial direction of the stator. The bridge portion of each of the coils in the second series extends across the bent portions of two adjacent coils in the first series. The coils in the first series and the coils in the second series are configured so that each series includes a mixture of coils of at least two phases among a U-phase, a V-phase, and a W-phase. Each of the coils in the first series is connected to a coil of the same phase in the second series.
