Embodiment 1

[0060] First Research Question: Comparative Analysis of Windings

[0061] Table 1 compares the performance of single-layer winding and double-layer winding. The results show that the efficiency, output power and loss of double-layer winding and single-layer winding are not much different.

[0062] For ultra-high-speed motors, due to the small inner diameter of the motor stator, the double-layer winding is not easy to insert wires. Although the overall performance of the single-layer winding scheme is reduced, compared with the double-layer winding, the performance difference of the motor is not large, so the single-layer winding with good manufacturability that is conducive to mass production is selected.

Description

technical field [0001] This application relates to the technical field of new energy vehicles, and specifically relates to an ultra-high-speed motor, an electric air compressor, and a new energy vehicle. Background technique [0002] Motors are common power devices. In particular, when applied to air compressors for new energy vehicles, the motor needs to have a higher speed. [0003] However, as the motor speed increases, its heat dissipation problem becomes a major problem restricting its work (poor heat dissipation will cause: the efficiency of the high-speed motor cannot meet the design requirements; at the same time, the insulation life of the motor is reduced, which may affect safety). [0004] For the problem of motor heat dissipation, many documents have been studied, such as: CN210468991U (Guangdong Heyi New Material Research Institute Co., Ltd.), CN207218461U (Jingji Technology Co., Ltd.), CN109245431A (Shijiazhuang Kingston Bearing Technology Co., Ltd.) and so on...
