Description

Technical Field

[0001] The utility model discloses a new energy motor cooling performance simulation test device, belonging to the technical field of testing equipment. Background Art

[0002] With the recent upgrade of national regulations for the automotive industry, emission and energy consumption standards have become increasingly stringent. In particular, the rapid development of new energy vehicles (NEVs), coupled with intelligentization, electrification, and the integration of multiple energy drive modes, has led to increasing system complexity. As electromechanical energy conversion devices, motors are widely used in NEV electric drive systems due to their high efficiency, reliability, and reasonable cost. Therefore, further improving motor efficiency and reducing motor manufacturing costs are key to upgrading the product competitiveness of NEVs.

[0003] Among existing technologies, permanent magnet synchronous motors (PMSMs) are favored by the new energy vehicle industry due to their high efficiency and high torque density. Compared to round wire motors, flat wire motors offer advantages such as high slot fill rate, low DC resistance, short end length, and higher efficiency. Therefore, flat wire motors are a future trend in new energy vehicles due to their high slot fill rate, low DC resistance, short end length, and higher efficiency. However, the operating temperature of flat wire motors directly affects their performance. Excessive temperature rise can lead to demagnetization of the permanent magnets. Therefore, before installing flat wire motors on vehicles, measuring their actual temperature rise and ensuring effective cooling is crucial for the electric drive system of new energy vehicles.

[0004] Due to the late development of flat wire motors, the industry has not yet developed any device or related equipment to effectively reduce the temperature rise of flat wire motors during actual vehicle operation. Utility Model Content
