Embodiment Construction
[0077] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0078] Such as Figure 1-Figure 6 As shown, the stator 1 according to the embodiment of the present invention includes a stator core 10 , a stator winding 20 , a boss 106 , a holder 30 and a plurality of bosses 106 . The stator core 10 includes a body 110, the body 110 includes a yoke 101 and a plurality of stator teeth 102, a stator slot 103 is defined between two adjacent stator teeth 102 and the yoke 101, and the stator winding 20 is wound on the stator teeth 102 superior. Wherein, the stator core 10 has a first end surface 104 and a second end surface 105 opposite in its axial direction. The stator winding 20 includes a first part 201 , a second part 202 a...

The invention relates to the technical field of motors, in particular to a stator, a motor, a compressor and refrigeration equipment. The stator comprises a stator core and a plurality of bosses, and the stator core is provided with a first end face and a second end face; the stator winding comprises a first part, a second part and a third part, the first part and the second part are located outside the stator slot, and the third part is located in the stator slot; the retainer comprises a first retaining part, a second retaining part and a third retaining part, the first retaining part is arranged on the first end face, the second retaining part is arranged on the second end face, and the two ends of the third retaining part are connected with the first retaining part and the second retaining part respectively; the bosses are arranged on the outer edge of the body at intervals in the circumferential direction of the stator core, and the outer edge of each boss is located on the outer side of the outer edge of the third holding part. The stator has the advantages of reducing the vibration noise of the motor comprising the stator, improving the efficiency of the motor comprising the stator and the like.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a stator, a motor, a compressor and refrigeration equipment. Background technique [0002] Rotary compressors in the related art generally use built-in permanent magnet motors as their motors. In recent years, with the increase in motor power density, higher requirements have been put forward for the vibration and noise of the motor, and the previous motors are increasingly unable to meet the requirements. Silent needs. Contents of the invention [0003] The present invention is based on the inventor's discovery and recognition of the following facts and problems: [0004] At present, the stator iron core of the motor is formed as a whole by pressing the stator punches and various fasteners, for example, riveting is used to connect the stator punches in the axial direction. The motor produces vibration noise for the following reasons: [0005] 1. Due to the low rigidity of th...
