Abstract: A stator includes: an A-phase coil, wound around four of 12 teeth and supplied with an A-phase current; a B-phase coil, wound around another four of the 12 teeth and supplied with a B-phase current; a C-phase coil, wound around yet another four of the 12 teeth and supplied with a C-phase current. The A-phase coil includes a transition part extending along the cylindrical part on an axial side between the teeth spaced apart in the circumferential direction. The B-phase and C-phase coils each include a transition part extending along the cylindrical part on another axial side between the teeth spaced apart in the circumferential direction. The turns of the first A-phase coil are one turn fewer than the turns of the first B-phase coil and the turns of the first C-phase coil.
