Abstract
A field element includes magnetic poles having polarities alternate in a circumferential direction. A multi-phase armature winding includes a phase winding including winding segments for each phase. An armature is tooth-less and includes a cylindrical armature core. The winding segment includes a pair of intermediate conductor portions at a predetermined interval in the circumferential direction and link portions connecting the intermediate conductor portions in an annular shape. The intermediate conductor portions and the link portion include multi-wound conductive wire members. The intermediate conductor portions are disposed side by side along a curved surface on a peripheral surface of the armature core. The intermediate conductor portion has a rectangular transverse section. A dimension between the end surface of the intermediate conductor portion on the armature core side and the armature core in the radial direction differ in the circumferential direction.
