ROTOR FOR GENERATOR |
| 摘要 |
In a rotor for a generator in which a rotor core is fixed to a rotary shaft rotatably supported by a housing, and field coils are wound on a bobbin installed in the rotor core, so as to be disposed on opposite sides of one plane passing a center axis of the rotary shaft, parts of the bobbin corresponding to axial outer ends of the rotor core are provided with separation protrusions by each of which a corresponding one of coil end portions at opposite ends of each of the field coils in an axial direction of the rotary shaft is divided into an inner portion and an outer portion in a radial direction of the rotary shaft, and on opposite sides of each of the separation protrusions in a peripheral direction of the rotary shaft, gaps are respectively formed between the inner portion and the outer portion. |

1. A rotor for a generator in which
a rotor core is fixed to a rotary shaft rotatably supported by a housing, and field coils are wound on a bobbin installed in the rotor core, so as to be disposed on opposite sides of one plane passing a center axis of the rotary shaft, wherein parts of the bobbin corresponding to axial outer ends of the rotor core are provided with separation protrusions by each of which a corresponding one of coil end portions at opposite ends of each of the field coils in an axial direction of the rotary shaft is divided into an inner portion and an outer portion in a radial direction of the rotary shaft, and on opposite sides of each of the separation protrusions in a peripheral direction of the rotary shaft, gaps are respectively formed between the inner portion and the outer portion. |
