Rotary electric machine

A rotary electric machine comprising:

• a field element having a plurality of magnetic poles having polarities that are alternate in a circumferential direction;
• an armature including an armature winding and an armature core, the armature winding being multi-phase and including a phase winding including a plurality of winding segments for each phase, the armature core being tooth-less, in a cylindrical shape, and opposed to the field element in a radial direction of the armature winding, wherein
• the field element and the armature face each other in the radial direction,
• each of the winding segments includes a pair of intermediate conductor portions and link portions,
• the pair of intermediate conductor portions are provided at a predetermined interval in the circumferential direction,
• the link portions are provided on one end side and an other end side of the pair of intermediate conductor portions in an axial direction, in an annular shape, and connect the pair of intermediate conductor portions,
• the pair of intermediate conductor portions and the link portions include a conductive wire member that is multi-wound,
• in the pair of intermediate conductor portions, rectangular transverse sections of the conductive wire member are arranged in the radial direction and in the circumferential direction, the pair of intermediate conductor portions are provided side by side along a curved surface of an outer peripheral surface of the armature core or a curved surface of an inner peripheral surface of the armature core,
• each of the pair of intermediate conductor portions has a rectangular transverse section, and
• a dimension between an end surface of the intermediate conductor portion, which is on a side of the armature core in the radial direction, and the armature core in the radial direction differs in the circumferential direction.
