Abstract:
In a rotary electric machine, a field coil member includes a first edgewise coil composed of a plurality of coaxially layered convolutions. The coaxially layered convolutions are wound around the outer periphery of the first pole core. The field coil member includes a second edgewise coil composed of a plurality of coaxially layered convolutions. The coaxially layered convolutions are wound around the outer periphery of the second pole core. The field coil member includes a link portion connecting between the first edgewise coil and the second edgewise coil in series. One of the first and second edgewise coils has one coil end extending therefrom to cross over the link portion at a crossover portion thereof. The crossover portion between the one coil end and the link portion is arranged to be non-overlapped with the convolutions of the one of the first and second edgewise coils.
