Abstract
It is realized that a shape of a bus ring is simplified, and a rotary electric machine is downsized. A coil connecting portion, which is protruded from bus ring maintaining portions to a shaft direction, is provided at a bus ring, and coil terminals are arranged in such a way that the coil terminals are protruded toward an outer side in a diameter direction with respect to the coil connecting portion, and the coil terminals and the coil connecting portion are connected by performing a resistance welding process. Thereby, it is not required that a slit and a bent portion or the like are formed at a tip of the bus ring, and a shape of the bus ring is simplified. Moreover, a welding board for a welding process and a chuck board for a connecting portion are not required, so that a rotary electric machine can be downsized.
