Embodiment Construction

[0024] 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.

[0025] Such as Figure 1~3 with Figure 5-6 As shown, the stator core 1 provided by the embodiment of the present invention includes a stator yoke 10 and a plurality of stator teeth 112 arranged on the stator yoke 10. Each split body 11 includes a sub-yoke 111 with a thickness smaller than that of the stator yoke 10 and a stator tooth 112 arranged on the sub-yoke 111. The sum of the thicknesses of each sub-yoke 111 is equal to that of the stator yoke 10. thickness, each stator tooth 112 of each split body 11 is respectively staggered and arranged on the stator core 1 along the circumferential dir...

Abstract

The invention belongs to the field of motors, and discloses a stator iron core, a stator and a motor. The stator iron core comprises a stator yoke and multiple stator teeth arranged on the stator yoke, the stator iron core is formed by axially stacking split bodies of which the number is the same as that of the stator teeth, and each split body comprises a sub-yoke and a stator tooth, wherein the thickness of each sub-yoke is smaller than that of the stator yoke, and each stator tooth is arranged on the corresponding sub-yoke. The sum of the thicknesses of the sub-yokes is equal to the thickness of the stator yoke, and the stator teeth of the split bodies are arranged in the circumferential direction of the stator iron core in a staggered mode. Due to the facts that the stator iron core is axially divided into the split bodies of which the number is the same as that of the stator teeth, in the production process, firstly, independent winding is performed on each split body, and then the split bodies where winding is completed are axially stacked to form the overall stator, the winding efficiency of the stator is improved, the slot fullness rate of the stator is increased, the performance of the motor is improved, the roundness precision of the stator is guaranteed, and the assembling process is simplified.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a stator core, a stator with the stator core, and a motor with the stator. Background technique [0002] A traditional manufacturing method of the motor stator is as follows: First, the stator punches are punched out as a whole, and then the stator punches are laminated to form an integral stator core, and then the stator winding is wound on the integral stator core by a winding machine . The traditional manufacturing method of the stator has the following defects in specific applications: due to the limitation of the winding space requirements, the slot fill rate is not high, and the opening of the slot on the stator core needs to be designed larger, which affects the Improved motor performance. [0003] In order to solve the above-mentioned technical problems in the traditional stator manufacturing method, the prior art proposes two schemes for winding the stator core separately: [00...
