US Patent 10404125 Motor

A stator includes conductive wires wound around teeth, and slots between adjacent teeth in a circumferential direction. The conductive wires include conductive wires of three phases corresponding to a U-phase, a V-phase, and a W-phase, and the conductive wires are delta connected. Coils, in which any one of the conductive wires is wound around the teeth, are repeatedly disposed in order of the U-phase, the V-phase, and the W-phase in the circumferential direction. In each of the U-phase, the V-phase, and the W-phase, at least two coils are connected in series and adjacent in the circumferential direction. A direction in which the U-phase and W-phase conductive wires are wound around the teeth and a direction in which the V-phase conductive wire is wound around the tooth are opposite.
