Patent ID: 8476800

Claim:
A three-phase motor comprising: a bearing structure comprising a bushing; a rotor structure comprising a shaft and a magnetic body, wherein the shaft is disposed in the bushing; and a stator structure disposed corresponding to the rotor structure and comprising a first coil assembly and a second coil assembly overlapped on the first coil assembly, wherein the first coil assembly comprises a plurality of first coils and the second coil assembly comprises a plurality of second coils, the magnetic body is disposed corresponding to the stator structure, wherein one of the first coils of the first coil assembly and one of the second coils of the second coil assembly having the same phase are disposed relative to each other with an included angle, wherein the included angle and the pole pair number of the magnetic body comply with the equation: θ m =2×180°/P, wherein θ m is the included angle, and P is the pole pair number of the magnetic body.
