Axial Gap Rotary Electric Machine

Abstract

To reduce an axial voltage while securing a high output, high efficiency, and assemblability of an axial gap rotary electric machine. An axial gap rotary electric machine includes: a stator, formed by arranging a plurality of core members circularly about a shaft in a direction in which magnetic lines are parallel with the shaft, the core member having at least an iron core and a coil wound around an outer circumference of the iron core; at least one rotor facing the stator with a predetermined air gap interposed therebetween in a shaft axial direction; and a housing having an inner circumferential surface opposing the stator and the rotor in a radial direction. The axial gap rotary electric machine further includes a wiring board that has: a bus portion continuous in the circumferential direction; a coil connection portion protruding from the bus portion and connected to the coil; and an external connection portion protruding from the bus portion. The wiring board is arranged at an outer circumferential side of the plurality of circularly-arranged iron cores.
