| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a rotary electric machine with improved cooling performance.SOLUTION: A rotary electric machine 1 including a rotor 20 having a plurality of field magnetic poles 30 formed in a circumferential direction by winding a field winding 50 around a magnetic pole iron core 40, has a plurality of insulating plates 81, 82, 83 and 84 disposed by being in contact with the field winding 50. One of the plurality of insulating plates 81, 82, 83 and 84 is made of aluminum oxide.SELECTED DRAWING: Figure 1
【課題】冷却性能を高めた回転電機を提供することにある。【解決手段】界磁巻線５０が磁極鉄心４０に巻装されてなる界磁極３０を周方向に複数有する回転子２０を備えた回転電機１であって、界磁巻線５０と接触して配置される複数の絶縁板８１，８２，８３，８４を有し、複数の絶縁板８１，８２，８３，８４の何れか１つが酸化アルミニウム製であるようにした。【選択図】図１ |
