ROTATING ELECTRICAL MACHINE

The invention aims to provide a rotating electrical machine which can effectively cool a rotor. The rotating electrical machine (1) includes a stator (12) and a rotor (14). The rotor (14) includes a rotor core (24) including embedding holes (34), permanent magnets (26), a first end plate (2), and a second end plate (5). Each of the embedding holes (34) includes a loading region (34a), an outer peripheral space (34c) and an inner peripheral space (34b). A first guide groove (G1) of the first end plate (2) covers one or more outer peripheral spaces (34c) and one or more inner peripheral spaces (34b). The second end plate (5) exposes all the outer peripheral spaces (34c) and all the inner peripheral spaces (34b) which are covered with the first end plate (2). 本发明的课题在于提供一种能够将转子有效地冷却的旋转电机。旋转电机(1)具备：定子(12)；以及转子(14)，具有：具有多个埋入孔的转子铁心(24)、多个永磁铁(26)、第一端板(2)、第二端板(5)。上述埋入孔包含：装填区域、外周侧空隙区域(34c)、内周侧空隙区域(34b)。第一端板(2)的第一引导槽(G1)覆盖1个或者多个外周侧空隙区域(34c)以及1个或者多个内周侧空隙区域(34b)。第二端板(5)使第一端板(2)覆盖的所有的外周侧空隙区域(34c)以及所有的内周侧空隙区域(34b)露出。
