| Zusammenfassung: | To provide a rotor for a motor in which generation of an eddy current is further suppressed.SOLUTION: A motor rotor includes a rotor extending along an axis and a holding body formed of metal and holding the rotor from an outer peripheral side. The holding body is provided with a plurality of annular members annularly surrounding an outer peripheral surface of the rotor and arranged at intervals in an axial direction, and a plurality of connecting members arranged in a circumferential direction so as to connect adjacent annular members. Thus, a path of an eddy current is limited, and the eddy current can be reduced.SELECTED DRAWING: Figure 2
【課題】渦電流の発生がさらに抑制された電動機用ロータを提供する。【解決手段】電動機ロータは、軸線に沿って延びる回転子と、金属から形成されて、回転子を外周側から保持する保持体と、を備え、保持体は、回転子の外周面を環状に囲うとともに軸線方向に間隔をあけて配置された複数の環状部材と、隣り合う環状部材の間で、これら環状部材を接続するように周方向に複数が配列された接続部材と、を有する。これにより、渦電流の経路が限定され、当該渦電流を低減することができる。【選択図】図２ |
