Abstract
This paper proposes a low-cost permanent magnet synchronous motor (PMSM) with soft magnetic composite (SMC) and ferrite permanent magnet (PM) for home applications. The main novelty of this proposed motor is that it combines two relatively cheap magnetic materials in an axial flux switching permanent magnet motor (AFSPMM). By using the ferrite PM and SMC material, the material cost and manufacture cost of AFSPMM can be reduced greatly. A 675 W 3600 rpm AFSPMM is designed and analyzed in this paper. The commercial finite element method (FEM) package ANSOFT is used to analyze the motor performance and the d-axis current is set to zero to achieve the optimum torque characteristic.
