Summary:To provide a rotary electric machine capable of preventing a leakage magnetic flux from being interlinked with a rotor, and of improving a drop rate of a torque constant to an extraction amount of a stator, even when moving either the stator or the rotor so as to be extracted.SOLUTION: There are provided a stator comprising a stator core around which an armature coil is wound, and a rotor comprising a rotor core where a plurality of permanent magnets are annularly arranged while being freely rotationally arranged with respect to the stator in a radial direction via a predetermined gap. Either the stator or the rotor is arranged along a rotational shaft direction of the rotor in a freely insertable/extractable manner and a leakage magnetic flux absorption part is provided at an end of the rotor in an extraction direction of the stator.SELECTED DRAWING: Figure 1 【課題】ステータとロータのいずれか一方を引き抜くように移動させた場合であっても、漏れ磁束がロータと鎖交するのを防止し、ステータの引抜量に対するトルク定数の低下率を向上させることができる回転電機を提供する。【解決手段】電機子コイルを巻回したステータコアを有するステータと、前記ステータに対して径方向に所定のギャップを介して回転自在に配置されると共に、複数の永久磁石を環状に配置したロータコアを有するロータと、を備え、前記ステータと前記ロータの何れか一方は、前記ロータの回転軸方向に沿って抜き差し自在に配置され、前記ステータの抜き方向の前記ロータの端部には、漏れ磁束吸収部を備えることを特徴とする。【選択図】図１
