Abstract:
The present invention comprises: a stator core (1) having a plurality of teeth (12) with a prescribed space therebetween in the circumferential direction (Z) of a yoke part (11); a coil (7) formed by winding a coil of wire (70) round each of the teeth (12); and an upper winding frame (2) disposed between and insulating the stator core (1) and the coil (7). The upper winding frame (2) has a first protrusion (21) protruding from the stator core (1) from one side of an axial direction (Y) and has a groove (9) composed of multiple stages in the axial direction (Y) on an outer circumferential surface (201) on the outside (X1) in a radial direction (X) of the first protrusion, a crossover (8) for connecting the coils (7) of different teeth (12) with each other being a continuous wire and being held in the groove (9).
