Summary:A motor includes a motor case, and a rotor and a stator, which are disposed in the case. The case has a tubular portion, a front cover mounted to an axial end of the portion, and a rear cover mounted to the other axial end of the portion. The rotor has a rotary shaft and the stator includes a plurality of teeth, which extend toward a central axis of the shaft and are circumferentially disposed at equal intervals. Between each circumferentially adjacent pair of the teeth, a slot extending toward the axis is formed. In each slot, a U-shaped segment is inserted in parallel with the axis. The distal ends of the segments projecting out from the slots are electrically interconnected, thereby forming an SC coil including the segments disposed circumferentially. The SC coil includes a receiving terminal, and the terminal includes leads extending in parallel to the axis.
