Title:
ROTATING ELECTRIC MACHINE STATOR
Document Type and Number:
WIPO Patent Application WO/2014/188588
Kind Code:
A1
Abstract:
The purpose of this invention is to obtain a rotating electric machine stator capable of improving an anti-surge property without using a coated conductive wire to which an anti-surge property is imparted, in such a way that an insulating tube is mounted on the root side of a portion extending from a first turn which is the winding start of a first coil on the input side of each phase winding constituted by concentrated winding coils. The rotating electric machine stator according to the invention comprises: a stator core having a ring-shaped yoke and a plurality of teeth each projecting from the inner circumferential surface of the yoke toward a diameter direction inner side and arranged in a circumferential direction; and a stator coil constituted by a three-phase AC connection of concentrated winding coils that are fabricated by winding a coated conductive wire around each of the teeth. In the rotating electric machine stator, an insulating tube is mounted on the root side of a portion extending from a first turn which is the winding start of the first concentrated winding coil from the input side of each of the phase windings of the stator coil. The insulating tube is disposed at the intersection of the portion extending from the first turn which is the winding start of the first concentrated winding coil and a portion extending from the final turn.
