Abstract

A stator of a rotary electric machine includes a stator core and a coil. The stator core is such that a plurality of teeth that protrude out toward a rotor are arranged spaced apart from one another, and a slot is arranged between the teeth. The coil passes through the slot and is wound around the teeth. The coil includes an assembly or assemblies of conductors, each of which is formed by an assembly of a plurality of wires. The assembly or assemblies of conductors are arranged in the slot, stacked in the slot in a direction in which the teeth protrude, and wound around the teeth. Each of the assemblies of conductors is twisted in the slot, and an arrangement of the plurality of wires in the slot is reversed an odd number of times.
