| Abstract(E) | Compact and high-torque motor is required for small electric vehicles. In this development, a high-torque density was realized by using soft magnetic composite cores with maximizing the number of coil turns and arranging an optimum 3D magnetic circuit. Also keeping a higher level of motor torque, cogging torque was minimized with optimizing the geometry of magnets and cores, then finally the practical use of the axial gap motor for the small electric vehicles was achieved. |
