With the rise of new energy vehicles and continuous innovation in motor technology, new energy vehicle motors have become a core element driving the development of the new energy vehicle industry. The development of new energy vehicle motors is of great significance, not only benefiting environmental protection and energy conservation but also promoting the upgrading and transformation of the automotive industry, improving energy efficiency and economic benefits. New energy vehicles have become the mainstream direction of the automotive industry's development, and further innovation in motor technology will bring even broader development opportunities. Due to the unique characteristics of their power systems, new energy vehicles place higher demands on the performance and efficiency of their air conditioning systems, requiring rapid cooling and heating, as well as quiet and stable operation. Through optimized design and technological innovation, the air conditioning rotor in new energy vehicles can improve the response speed and adjustment accuracy of the air conditioning system, providing consumers with a more comfortable driving experience.

Therefore, we propose a new type of motor rotor structure. Utility Model Content
