Problems solved by technology

During the operation of the integral stator structure, the magnetic density of the yoke 11' is small, and the magnetic density of the teeth 12' is relatively large. The saturation of the magnetic density of the teeth affects and restricts the selection of the magnetic load of the motor to a certain extent, resulting in The operation is unstable, the iron loss is large, and the performance of the motor decreases

Embodiment Construction

[0028] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The same reference numerals denote the same or similar structures in the drawings, and thus their repeated descriptions will be omitted.

[0029] The stator core structure of the present invention is applicable to a motor structure with 6 poles and 9 slots, and also applicable to other types of motor structures with matching poles and slots. Wherein, the motor structure of 6 poles and 9 slots means that the stator of the motor structure has 9 stator slots, and the rotor has 6 magnetic poles, forming a motor structure of 6 poles and 9 slots. The stator core s...

Abstract

The invention relates to the technical field of compressors, and provides a stator core structure and a compressor. The stator iron core structure comprises a plurality of symmetrical arc-shaped yokeparts, wherein the inner circumferential surface of each arc-shaped yoke part is provided with tooth grooves recessed in the radial direction of the arc-shaped yoke part, and the arc-shaped yoke partsare spliced end to end to form an annular yoke part, the tooth grooves are distributed in the inner circumferential surface of the annular yoke part at equal intervals; and a plurality of removable teeth parts, wherein each tooth part is of a structure which is formed by winding a strip and can be embedded into the corresponding tooth groove in a matched mode, and each tooth part is embedded intothe corresponding tooth groove and extends from the corresponding tooth groove to the circle center of the annular yoke part in the radial direction of the annular yoke part. The stator core structure adopts the structure that the teeth parts and the yoke parts can be separately disassembled and assembled, and the teeth parts can be formed by winding strips with high magnetic conductivity and lowiron loss, so that the flux density of the teeth parts is effectively improved, the iron loss of the motor is reduced, and the performance of the compressor is improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a stator core structure and a compressor including the stator core structure. Background technique [0002] At present, the frequency conversion compressor adopts a concentrated winding motor, and its stator is an integral structure, and the yoke and the teeth are integrally formed. [0003] refer to figure 1 As shown, in the existing stator 1', the yoke portion 11' and the tooth portion 12' are integrally formed to form an integral stator structure. During the operation of the integral stator structure, the magnetic density of the yoke 11' is small, and the magnetic density of the teeth 12' is relatively large. The saturation of the magnetic density of the teeth affects and restricts the selection of the magnetic load of the motor to a certain extent, resulting in The operation is unstable, the iron loss is large, and the performance of the motor decreases. [0004] It sh...
