This paper focuses on the analysis of a surface-mounted V-shape permanent magnet assisted-synchronous reluctance motor (SVSPMa-SynRM) for light electric vehicles (LEVs) traction applications. For federal urban driving schedule (FUDS), most ELVs require traction motors that operates with smooth torque that has less ripple contents to contain noise and vibration. The proposed permanent magnet assisted-synchronous reluctance motor (PMa-SynRM) has a rotor with V-shape lamination cut-offs on the q-axis in the axial direction. The V-shape lamination cut-offs accommodate pieces of NdFeB-37 rare permanent magnet (PM) to obtain better electromotive force and less ripple torque. The proposed SVSPMa-SynRM is designed and modelled using 3-D finite-element method (FEM). The 3-D finite element analysis (FEA) results are compared to the results of other five different models. The combination of good torque performance and reduction of NdFeB-37 rare permanent magnet is tremendously achieved by the proposed motor as compared to other PM assisted-synchronous reluctance motors analysed in this paper.
