Abstract

A stator of a rotary electric machine includes a stator core having a plurality of slots along a circumferential direction of the stator core, the stator core including a slot insulator arranged along an inside wall of each of the slots; and a coil that is wound inserted into each of the slots, the coil having a coil conductor and a coil insulation coating that covers the coil conductor, a permittivity of the coil insulation coating differing from a permittivity of the slot insulator, and a thickness of the coil insulation coating differing from a thickness of the slot insulator.
