Abstract

The invention discloses a novel stator tooth pole structure which comprises a stator tooth pole body. The stator tooth pole body comprises an annular yoke part, the yoke part extends outwards to forma tooth part, the stator tooth pole body comprises a plurality of tooth parts which are uniformly arranged along the circumferential direction, and the tail end of each tooth part is provided with anarc-shaped tooth pole. An insulating layer is arranged on an inner side portion defined by the yoke portion, the tooth portion and the tooth pole, a winding is wound on the outer side of the insulating layer of the tooth portion, the included angle between one end of the tooth pole of the stator tooth pole body and a central axis is a smaller angle A, the included angle between the other end of the tooth pole of the stator tooth pole body and the central axis is a larger angle B, and the ratio of the smaller angle A to the larger angle B, namely A / B is between 0.85-0.99. According to the stator tooth pole structure, the tooth pole shape is subjected to magnetic circuit optimization and structure optimization, so that the torque chain wave of a fan motor can be reduced, the vibration and electromagnetic noise of a fan can be reduced, and the performance of the fan can be improved while the strength is ensured.

Description

technical field [0001] The invention relates to the technical field of fan motor manufacturing, in particular to a novel stator tooth pole structure and a novel fan motor including the structure. Background technique [0002] At present, with the progress of science and technology, people have higher and higher requirements for electronic products, especially the tolerance of vibration is getting lower and lower. As one of the few moving parts in electronic products, the improvement of fan vibration is particularly important to reduce the vibration of electronic products. [0003] At present, the shape of the tooth poles of the common stator core is not properly designed, which will cause the vibration of the fan to increase and cannot meet the needs of the consumer. Contents of the invention [0004] The purpose of the present invention is to overcome the above-mentioned defects in the prior art, and provide a novel stator tooth pole structure and a novel fan motor inclu...
