Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or there may be an intervening element at the same time. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0033] It should also be noted that the orientation terms such as left, right, up, down, top, and bottom in this embodiment are only relative concepts or refer to the normal use state of the product, and should not be regarded...

Abstract

The invention is suitable for the field of a series excitation motor and discloses a series excitation motor stator core, a series excitation motor stator, a manufacturing method of the series excitation motor stator and a series excitation motor. The series excitation motor stator core comprises a stator yoke and a plurality of stator teeth arranged on the stator yoke, wherein the stator yoke comprises first sub-yokes and second sub-yokes which are alternately arranged along a circumferential direction, each first sub-yoke is respectively connected with each stator tooth, each second sub-yoke is respectively connected with each stator tooth, both ends of the first sub-yoke are respectively provided with two first inserting parts, both ends of the second sub-yoke are respectively provided with two second inserting parts, said two first inserting parts on both ends of the first sub-yoke are respectively connected with said two inserting parts of said two second adjacent sub-yokes in an inserting way. Filling ratio, motor efficiency, winding efficiency, automation production degree and low-voltage start ability of the series excitation motor are improved, meanwhile vibration and noise at the junction of the stator tooth and the stator yoke can be avoided and vibration and noise of the series excitation motor are further reduced.

Description

technical field [0001] The invention belongs to the field of series-excited motors, and in particular relates to a series-excited motor stator core, a series-excited motor stator with the series-excited motor stator core, a manufacturing method of the series-excited motor stator, and a series-excited motor stator with the series-excited motor stator core. Exciter. Background technique [0002] Such as Figure 5 As shown, in the traditional washing machine series motor, the stator core is generally set as a shallow slot inclined shoulder structure, that is, the depth of the wire slot 13a (the distance from the pole piece 1221a of the stator tooth 12a to the stator yoke 11a) H2a is very small, extremely The inner wall 12211a of the shoe 1221a facing the slot 13a is inclined; and the neck length H1a of the stator tooth 12a is also relatively short. The stator winding 2a is usually wound on the stator tooth 12a of the stator core by double flyer winding. The traditional washing...
