Abstract:
A rotating electric machine including an edgewise coil formed of a rectangular wire is efficiently cooled. The edgewise coil is formed by winding the rectangular wire around a tooth. In order to wind the rectangular wire around the tooth of rectangular shape, supporting portions determining the position of the edgewise coil relative to the tooth are provided. A coolant flows through a cooling water channel provided between the tooth and the edgewise coil formed of the rectangular wire and positioned by the supporting portions.
