Abstract
The embodiment of the invention discloses a stator core, and the stator core comprises a stator core body. The peripheral wall of the stator core body is provided with a plurality of flow grooves which are through in the axial direction of the stator core body. The flow grooves are inclined grooves or spiral grooves which are inclined in the axial direction of the stator core body. According to the invention, the outer wall of the stator core body is provided with the plurality of flow grooves, and the flow grooves are inclined grooves or spiral grooves which are inclined in the axial direction of the stator core body. In other words, the inclined grooves or spiral grooves are used for replacing cut edges in the prior art. When a compressor is in operation and gas in a cavity of the compressor flows through the inclined grooves or spiral grooves, the gas is enabled to pass spirally, and the above structure is similar to a fan structure, thereby speeding up the flowing of gas. Because the flowing speed of gas is increased, the size of the inclined grooves or spiral grooves can be less than the size of the cut edges, thereby increasing the area of the stator core, and improving the performance of the compressor.
