PROBLEM TO BE SOLVED: To provide a rotary electric machine for an electric vehicle which achieves compactification of a yoke forming a stator or a rotor while securing the durability of the yoke and thereby achieves weight reduction and high efficiency.SOLUTION: A DC motor 100 includes a yoke holding body 106 coupled to a driving shaft 104a in an inner space of a housing 101 and a lid 102 which form an enclosure. The yoke holding body 106 is made of a CFRP material and is formed into a substantially cup shape where an annular part 106a formed into an annular shape and a side surface part 106b formed into a substantially plate shape are integrally molded. Multiple permanent magnets 108 are bonded to an inner peripheral surface of the annular part 106a and an annular yoke 109 made of a magnetic material is included in the annular part 106a. An armature 110 is provided at the inner side of the yoke holding body 106 while being fixed to the housing 101. The armature 110 comprises: an armature core 111 and an armature coil 112 wound around the armature core 111. |
