Rotating Electric Machine or Wind Power Generation System |
| 摘要 |
A rotating electric machine comprises a field winding provided on a rotor iron core and a neutral ring supported independently of the field winding, wherein: the field winding and the neutral ring are electrically connected to each other through a connecting wire; the neutral ring is disposed spaced with respect to the rotor iron core; and the connecting wire absorbs the stress difference between the field winding and the neutral ring when a centrifugal stress is applied. |

1. A rotating electric machine comprising:
a field winding provided on a rotor iron core; and a neutral ring supported independently of the field winding, wherein the field winding and the neutral ring electrically connected with each other through a connecting wire, the neutral ring is spaced from the rotor iron core, and the connecting wire absorbs a stress difference between the field winding and the neutral ring when a centrifugal force is applied. |
