To provide a rotary electric machine capable of easily placing rare-earth-based sintered magnets for a rotor of the rotary electric machine without processing into a tile shape.SOLUTION: A rotor 2 has facing surfaces 5 facing a stator 3 on a rotor core 2A manufactured by punching an electromagnetic steel sheet. The facing surface 5 has a plane having a polygonal shape that extends in a tangential direction of a circle centered on an axis C at a predetermined angle interval centered on the axis C of the rotor 2, and magnets 4 are arranged on the plane. In each magnetic 4, an N pole and an S pole are alternately arranged in a circumferential direction of the rotor 2. These magnets 4 form magnetic pole parts at intervals in the circumferential direction of the rotor 2.SELECTED DRAWING: Figure 1 【課題】回転電機のロータ用希土類系の焼結磁石を瓦形状に加工せずに容易に配置可能にする。【解決手段】ロータ２は、電磁鋼板を打ち抜いて製作したロータコア２Ａに、ステータ３に対向する対向面５を有する。対向面５は、ロータ２の軸心Ｃを中心とする所定角度間隔で、軸心Ｃを中心とする円の接線方向に延びる多角形形状の平面を有し、この平面に磁石４を配置している。各磁石４は、ロータ２の周方向にＮ極とＳ極とが交互に並ぶ。これらの磁石４により、ロータ２の周方向に間隔を空けて磁極部が形成される。【選択図】図１
