Abstract :
With the improvement of soft magnetic composite (SMC) material, electric machine design is no longer limited to the traditional iron lamination technology. The single extrusion fabrication process of the SMC material simplifies construction of machine armature core. Moreover, the isotropic material property can be exploited for various machine structure design, compared with the 2D flux distribution of typical iron laminations. In this paper, a drive system based on a novel multi phase modular permanent magnet machine is proposed. The concentric winding structure simplifies the stator structure with the benefit of less end winding loss, which also offers the potential of fault tolerant capability. The performance of the drive system is analyzed and discussed with the simulation results provided.
