Embodiment Construction

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below, obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0034] The existing two-phase 12 main pole hybrid stepping motor stator structure is as follows figure 1 Shown:

[0035] The stator 100 of the stepping motor has 12 completely identical stator main poles 1 to 12. The stator main pole 1 is divided into a stator pole shoe 1A and a stator main pole 1B. The center line of the stator main pole 1A and the stator pole shoe 1B is completely coincident.

[0036] When the included angles between the main poles are equal, the areas of the slots defined between the main poles a...

Abstract

The invention relates to a stepping motor stator and a motor with the stator. The stator comprises 12 stator main poles; each stator main pole comprises a stator main pole portion and a stator pole piece portion; the arrangement of the 12 stator main pole portions in the circumferential direction is different from that of the 12 stator pole piece portions in the circumferential direction; and thestator main pole portions are uniformly distributed in the circumferential direction to enable the included angles between adjacent stator main pole portions to be same. Compared with the prior art, the stepping motor stator and the motor with the stator have the following advantages that the motor stator slot utilization ratio is improved, and asymmetry of the main pole of each phase of the motoris reduced.

Description

technical field [0001] The invention relates to the field of motor structure, in particular to a stator of a stepping motor and a motor with the stator. Background technique [0002] The existing two-phase 12 main pole hybrid stepper motor stator 100 has 12 identical stator main poles 1-12 in total, and the stator main pole 1 is divided into a stator pole shoe part 1A and a stator main pole part 1B, and the stator pole shoe part The centerlines of 1A and stator main pole portion 1B are completely coincident. [0003] The angle between stator main pole 1 and stator main pole 2 is 29.7°; [0004] The angle between stator main pole 2 and stator main pole 3 is 29.7°; [0005] The included angle between stator main pole 3 and stator main pole 4 is 29.7°; [0006] The included angle between stator main pole 4 and stator main pole 5 is 29.7°; [0007] The included angle between stator main pole 5 and stator main pole 6 is 29.7°; [0008] The included angle between the stator m...
