Title:
ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/139100
Kind Code:
A1
Abstract:
A rotating electrical machine that comprises: a stator in which a plurality of core units that have a core and a coil are annularly arranged around a shaft center; a rotor that faces a flux end surface of the stator in the shaft-center direction with a prescribed gap therebetween; a housing that houses the stator and the rotor and has an outlet that guides a lead wire for the stator to the outside; and a resin that integrally molds the stator and an inner circumferential surface of the housing that includes the outlet. The inner diameter of the outlet becomes larger from the shaft-center side to the radial-direction outside. The outlet has an elastic member that keeps the resin from flowing to the outside of the housing. The elastic member has a hollow part through which the lead wire passes from the shaft-center side to the radial-direction outside. Pressure from a rotary-shaft radial direction seals between the hollow part and the lead wire. The resin fills to the shaft-center side of the hollow part or to one portion of the hollow part.
