Title:
AXIAL GAP TYPE ROTATING ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2017/145274
Kind Code:
A1
Abstract:
The purpose of the present invention is to reduce the shaft voltage while ensuring the high output, high efficiency, and assemblability of an axial gap type rotating electric machine. The axial gap type rotating electric machine has: a stator formed by arranging a plurality of core members circularly about a shaft in a direction in which magnetic lines run in parallel with the shaft, said core members each having at least an iron core and a coil wound around the outer perimeter of the iron core; at least one rotor facing the stator with a predetermined air gap interposed therebetween in the shaft axial direction; and a housing, the inner circumferential surface of which faces the stator and the rotor in the radial direction. The axial gap type rotating electric machine further has a wiring plate comprising: a bus portion continuous in the circumferential direction; a coil connection portion projecting from the bus portion and connecting with the coil; and an external connection portion projecting from the bus portion. The wiring plate is disposed on the outer circumferential side of the circularly arranged iron cores.
