Rotary electric machine

A rotary electric machine comprising:

• a field element having magnetic poles;
• an armature having a toothless structure, the armature including an armature winding being multiphase;
• an armature holder holding the armature;
• a position restriction member being a part of the armature holder or fixed to the armature holder, the position restriction member being located on a coil end of the armature and restricting movement of the armature winding;
• and
• an insulating layer insulating the armature winding from the position restriction member, wherein
• the armature winding includes winding segments forming phase windings for respective phases,
• each of the winding segments has an annular shape and includes
• a pair of intermediate conductor portions separated at a predetermined interval in a circumferential direction of the armature, and
• crossover portions provided on one end and another end of the pair of intermediate conductor portions in an axial direction of the armature, the crossover portions connecting the pair of intermediate conductor portions to form the annular shape,
• different pairs of intermediate conductor portions of the winding segments are arranged in the circumferential direction and close to each other,
• the position restriction member restricts movement of the winding segments attached to the armature holder, and
• the insulating layer is interposed between each of the winding segments and the position restriction member.
