[0002] The stators of new energy vehicle drive motors use oil cooling technology, primarily to address the heat dissipation challenges under high power density. The stators generate a large amount of heat during operation, especially in the windings and core. Insufficient heat dissipation can lead to excessive temperatures, affecting motor performance and life. Oil cooling technology has become the first choice for high-end new energy vehicles, ensuring stable operation of the motor under high temperature and high load conditions, thereby extending its service life.

[0003] The current motor stator oil cooling structure still has the following problems:

[0004] 1. Generally, there is a lack of cooling oil separation structure, which makes it impossible to accurately control the cooling oil suction position when the cooling oil circulates; and when the cooling oil circulates, the oil suction position and oil discharge position are fixed, resulting in insufficient circulation of the cooling oil, which easily leads to different cooling oil temperatures at different positions;

[0005] 2. New energy vehicle drive motors are usually installed with bolts, which makes the installation and disassembly of new energy vehicle drive motors inconvenient; and there is no automatic limiting effect on the installation screws, which causes the installation screws of new energy vehicle drive motors to loosen easily after long-term use.
