Abstract:
A multi-gap type rotary electric machine is provided, where the machine is provided a shaft supported rotatably by a baring secured to a housing. An annular rotor is secured to the shaft and configured to rotate together with the shaft. Double stators are secured to the housing and configured to have gaps between the stators and the rotor. Relationships of: 3.5 1 (2) are met, where P6 denotes a circumferential width of each of outer salient poles, P7 denotes a circumferential width of each of inner salient poles, and P13 denotes a circumferential width of each of the outer magnets.
