DETAILED DESCRIPTION OF THEPREFERRED EMBODIMENTS
The present invention will be further described in conjunction with the accompanying drawings and the specific embodiments.

FIG. 3 is a schematic diagram of a stator without a stator bracket, and FIG. 4 is a schematic diagram of a stator with a stator bracket. As shown in FIGS. 3 and 4, the motor 10 comprises a rotor (not shown) , a stator 5, and a stator bracket 52. The stator 5 comprises a stator laminate 51, an end surface 54 of stator laminate, and a stator slot. A winding 11 is wound on the stator slot of the stator 5, and the stator 5 is equipped with an upper end plate 12 of the stator and a lower end plate (not shown) , which fit together to bound the shape of the winding 11.
As shown in FIGS. 1 to 4, the stator bracket 52 comprises a sheet portion 521 mounted on the end surface 54 of the stator laminate, and a rod portion 522 protruding from the sheet portion 521 for fixing the sheet portion 521 to the end surface 54 of the stator laminate. In an embodiment, the end surface 54 of the stator laminate has a hole 53 which extends through the stator laminate 51. The rod portion 522 may be inserted into the hole 53 from the end surface 54 of the stator laminate to fix the sheet portion 521 to the stator.
The outer peripheral side of the stator laminate 51 may be approximately annular, and an upper end plate of the stator may be annular. The stator bracket 52 may be a plastic member.
As shown in FIGS. 1 to 4, the stator laminate 51 may have a plurality of corner portions arranged along the circumferential direction, for example with four corner portions. The hole 53 is provided at at least one corner portion of the stator laminate 51, and the axial direction of the hole 53 is parallel to the axial direction of the stator laminate 51. The hole 53 may be at least one of mounting holes 53 for mounting the stator 5. In general, the stator laminate 51 of the stator 5 has 4 mounting holes 53, two of which are used to fix the stator, the remaining  two may be used to install the stator bracket 52. In an embodiment, the hole 53 may be a through hole, and a rod portion 522 is inserted into the through hole 53 and forms interference fit with the through hole 53 so as to fix the sheet portion 521 to the end surface 54 of the stator laminate. The rod portion 522 may be a connecting pin, and the surface of the sheet portion 521 away from the end surface of the stator laminate may be used as anti-collision surface.
As shown in FIG. 4, a portion of the sheet portion 521, which faces toward the outer peripheral side of the end surface 54 of the stator laminate, and the corresponding portion of periphery of the end surface 54 of the stator laminate may have same or similar profile. Furthermore, an edge of the sheet portion 521, which faces toward the inner peripheral side of the end surface 54 of the stator laminate, and the corresponding portion of an outer peripheral side of the upper end plate 12 of the stator have the same or similar profile and have a predetermined gap therebetween. Therefore, the stator bracket 52 has a three-dimensional structure. Because the stator bracket 52 has a shape fit with the upper end plate 12, it will not cause the rotation of the stator bracket 52, even if the upper end plate 12 moves in a certain range, thereby a fixed position of the stator bracket on the end surface 54 of the stator laminate can be maintained. Moreover, the stator bracket 52 is made of plastic material, which will provide buffer effect to weaken collision force, even if collision between the motor stator and other portions in the compressor is generated, thereby protecting the motor stator and avoiding the collision between metal and metal, thus noise may be further reduced. Furthermore, the structure of the stator bracket is simple and reasonable, and easy to process. Because current mounting holes of the motor stator are used to install the stator bracket, cost can be saved.
According to above-mentioned technical solutions of embodiments of the invention, through using the stator bracket, the noise generated by the collision between the stator bracket of the motor stator and other parts is reduced or eliminated in case that the compressor is used in the vehicle refrigeration system.
Although embodiments of the invention have been shown and described, it should be understood by those skilled in the art that various changes, modifications, replacements and variations can be made in the present invention without departing from the scope and spirit thereof. The scope of the invention is limited by the appended claims and equivalents thereof.
