摘要：

This paper presents a novel toroidal motor configuration designed to achieve high torque density. The motor utilizes ring-shaped magnets and toroidal concentrated windings with an SMC core to enable 3D flux path. The proposed design is simulated using 3D FEA and compared to conventional PMSMs. The simulation results show that the proposed design can achieve at least 30% higher output torque compared to radial and axial flux PMSMs. In addition, thermal analysis of the motor shows the potential for a highly efficient magnet cooling that can enhance the motor reliability at high loading conditions and enable the possibility of using lower grade magnets.
