All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1 to 4, an electric motor having a cooling structure includes a housing assembly, a motor shaft assembly, and a stator 7.
The shell component comprises a shell 1, an inner cylinder 2, a left end cover 3, a right end cover 4, a left end seal 5 and a right end seal 6. The shell 1 and the inner cylinder 2 are both cylindrical. The left end cover 3 is fixedly arranged at the left end of the shell 1, and the right end cover 4 is fixedly arranged at the right end of the shell 1. The upper end of the left end cover 3 is provided with a cooling liquid adding port 301.

The inner surface of the housing 1 is provided with a spiral cooling liquid flow passage 101. The inner cylinder 2 is cylindrical, and the inner cylinder 2 is tightly attached to the inner surface of the shell 1 so that the spiral cooling liquid flow channel 101 is closed. The casing 1 is provided with a cooling liquid inlet 102 and a cooling liquid outlet 103 which are communicated with the spiral cooling liquid flow channel 101. The stator 7 is fixedly mounted within the housing assembly. The stator 7 is mounted by radially interference-fitting the inner cylinder 2 against the housing 1.
