Abstract: A coil assembly includes a strip member having a width in an axial direction, a length in a circumferential direction, and a thickness in a radial direction of a coil assembly. The strip is rolled in the circumferential direction into a plurality of turns stacked on one another. The coil group includes a plurality of coils made from an electrically conductive material. The coils are arranged in a length direction of the strip. Each of the coils is shaped, to have an open end facing in a first width direction and a closed end facing in a second width direction opposite the first width direction. Two of the coils arranged adjacent each other in the length direction of the strip are connected in a preselected way on a first width end facing away from a second width end portion of the strip in the first width direction.

Abstract: A first end contact portion of a first frame end contacts one end surface of a stator core. A second end contact portion of a second frame end contacts the other end surface of the stator core and includes an inner tubular part, which contacts the other end surface of the stator core, and a fixing part, which projects radially outward from the inner tubular part and contacts the other end surface. A through-bolt is threaded into the fixing part. An outer diameter of the one end surface is smaller than an outer diameter of an opposing surface of the first end contact portion. An outer diameter of an opposing surface of the inner tubular part is smaller than an outer diameter of the other end surface. A yoke of the stator core includes a relief groove, into which a portion of the through-bolt is fitted.
