FAN MOTOR AND AIR CONDITIONER PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2012/046274
Kind Code:
A1
Abstract:
A fan motor (100) is provided with a rotor (10) disposed on the periphery of a blade part (20), and a stator (30) positioned on the outer circumferential side of the rotor (10). The stator (30) is provided as one set of stators (30a to 30c). The stator 30a is provided with a first group of teeth in which U-phase tooth, a V-phase tooth, and a W-phase tooth are sequentially positioned; the stator 30b is provided with a second group of teeth in which a V-phase tooth, a W-phase tooth, and a U-phase tooth are sequentially positioned; and the stator 30c is provided with a third group of teeth in which a W-phase tooth, a U-phase tooth, and a V-phase tooth are sequentially positioned. The coil of each group of teeth is wound in the same direction. The stator 30a to stator 30c are positioned in such a manner that the teeth of the same phase in each group of teeth are in a position separated by an electrical angle of only an integral multiple of 360°, and the coils wound around the teeth of the same phase of the stators 30a to 30c are connected in a series.
