Abstract: Two types of insulating members, i.e., end surface insulators and slot insulators are provided. On tooth portion sides of both side surfaces in the circumferential direction of tooth end surface covering portions of the end surface insulator, first cutouts recessed in the circumferential direction are provided so as to extend in the radial direction. A part axially upward of the first cutouts protrudes in the circumferential direction to form a first overhang portion, and the slot insulator is accommodated between the first overhang portions of two end surface insulators.

Abstract: A stator includes an iron core cylindrical part, multiple teeth, and a coil. The iron core cylindrical part has multiple circular arc-shaped core back parts. The teeth radially inwardly protrude from an inner circumferential wall surface of the iron core cylindrical part. The coil is wound around each of the teeth. A first coil and a second coil are disposed so as to hold a temperature measuring element therebetween. The first coil has an outer surface provided with a gap made of a recess or a space, which is formed by skipping winding a coil wire. The temperature measuring element for measuring temperature of the coil is inserted in the gap and is assembled.
