| New energy vehicles and in-wheel motors have become the forefront of technology and popular industries in recent years.YASA aims to commercialize the axial flux motor (YASA: Yokeless And Segmented Armature). On the basis of the traditional single-stator dual-rotor axial flux motor, the stator yoke is removed, and the stator teeth They are independent of each other, and the individual stator teeth are connected together by lightweight non-magnetic materials. Major auto manufacturers are very optimistic about the application of axial flux motors as in-wheel motors. Judging from the number of patent applications for axial flux motors by Mercedes-Benz鈥檚 acquisition of YASA motors and Huawei, BYD Auto and other manufacturers, everyone They have invested a lot of research and development efforts and funds. From a global perspective, the research and innovation enterprises in axial flux motor technology include YASA, SAIETTA, AVID, Belgian MAGNAX, Switzerland Phi-power, American Arnold, China's disk hub power, magnetic Leige and other well-known enterprises. In the selection of stator core materials for in-wheel motors, the main materials to choose from are non-oriented steel, stator core made of laminated oriented steel, and SMC core materials. In the evaluation and selection of materials, there is nothing more than the compressive strength, the output torque when the small current is excited, and the output torque when the large current is excited. For the stator core of the in-wheel motor with topology structure, SMC is undoubtedly the best choice. The material is metallurgically formed, with high efficiency and obvious cost advantages. In terms of mold opening, SMC Prototypes can also be used to verify the electrical parameters of the in-wheel motor without opening the mold. If all aspects are satisfied, the mold can be opened, which can greatly reduce the early development investment of motor companies.SMC Cores factory website:http://www.highmagnets.com/smc-cores/ |
