STATOR FOR ROTATING ELECTRIC MACHINE

원문 (중국어)

A stator for a rotating electric machine includes a stator core including a tubular yoke and teeth, coils that are formed by windings wound around the teeth, and insulators. The insulators each include a tubular insulator base. The insulator base includes a first circumferential surface at a first side in the radial direction of the yoke, a second circumferential surface at a second side opposite to the first side in the radial direction, lead-out grooves each of which leads a lead wire of a coil from the first side to the second side in the radial direction, and return grooves each of which returns the lead wire, led out through a lead-out groove, from the second side to the first side in the radial direction. Each lead-out groove holds the lead wire by interference fit. Each return groove holds the lead wire by loose fit.
