| 摘要 |
The present invention provides a motor stator comprising a stator body; a stator casing which circumferentially surrounds the outer contour of the stator body and is fitted on said stator body; a first end cap and a second end cap which are respectively located on the two side ends in the axial direction of said stator casing; a cooling flow passage for the stator which is distributed in said stator casing, first end cap, and second end cap; and fasteners which are used to fasten the stator casing and the end caps on the two sides to form the sealed structure of said cooling flow passage. Through the design of a brand-new stator structure with a cooling flow passage, the present invention makes it possible that a relatively simple extrusion process can be applied to improve the yield of finished products and lower the manufacturing cost. |
