Provided is an electrical rotating machine capable of achieving both an increase in the number of turns of a stator coil and a suppression of an increase in the magnetic resistance of a stator core (11). A motor (1) includes a stator (2). The stator (2) includes: a stator core (11) including a cylindrical yoke (21) extending in an axial direction and a plurality of teeth (22) extending inwardly of the yoke (21) from an inner circumferential surface of the yoke (21); and a stator coil (12) wound around the teeth (22). The stator core (11) is a dust core that uses particulates including particles of a magnetic material, and includes a plurality of yoke pieces (21a) having fracture surfaces (21 b) disposed relative to each other along a circumferential direction of the yoke (21). Each of the teeth (22) is provided on each of at least some of the plurality of yoke pieces (21a) having the fracture surfaces (21b). The fracture surfaces (21b) of mutually adjacent yoke pieces (21a) of the plurality of yoke pieces (21a) having the fracture surfaces (21 b) are in contact with each other. |
