Zusammenfassung: | To facilitate connection between positive electrode-side and negative electrode-side slip rings and magnetic field winding of a rotor.SOLUTION: There is disclosed a winding magnetic field type rotary electric machine, wherein a rotation-side power supply device has positive electrode-side and negative electrode-side slip rings each having a toric shape around a rotor shaft, a positive electrode-side rotor connection part arranged more axially closely to a rotor than the positive electrode side and negative electrode-side slip rings, and electrically connected to the positive electrode-side slip ring and magnetic field winding, a negative electrode-side rotor connection part arranged more axially closely to the rotor than the positive electrode-side and negative electrode-side slip rings, and electrically connected to the negative electrode-side slip ring and the magnetic field winding, and a resin part uniting the positive electrode-side slip ring and rotor connection part, and the negative electrode-side slip ring and rotor connection part, and the positive electrode-side and negative electrode-side rotor connection parts each extend over an angle rnage of 90 degrees or more around the rotor shaft.SELECTED DRAWING: Figure 4
【課題】正極側及び負極側のスリップリングとロータの界磁巻線との間の接続を容易化する。【解決手段】巻線界磁式回転電機であって、回転側の給電装置は、ロータ軸まわりの円環状の形態をそれぞれ有する正極側及び負極側のスリップリングと、正極側及び負極側のスリップリングよりも軸方向でロータに近い側に配置され、正極側のスリップリングと界磁巻線に電気的に接続される正極側のロータ接続部と、正極側及び負極側のスリップリングよりも軸方向でロータに近い側に配置され、負極側のスリップリングと界磁巻線に電気的に接続される負極側のロータ接続部と、正極側のスリップリング及びロータ接続部と負極側のスリップリング及びロータ接続部とを一体化する樹脂部と、を有し、正極側及び負極側のロータ接続部は、それぞれ、ロータ軸まわりの90度以上の角度範囲にわたって延在する、巻線界磁式回転電機が開示される。【選択図】図4 |
