N2 - This paper deals with the numerical analysis of the Synchronous Reluctance Motor (SynRM) with sinusoidal rotor shape in the axial direction using the 3D Finite Element Method (FEM), and presents the airgap magnetic flux governing equation derived from Kelvin-Stoke's theorem. In the Finite Element Analysis (FEA) the airgap flux density, machines performance indexes, the torque and its ripple contents are presented. In this paper three motors having different rotor anisotropies are modelled and analyzed. The SynRM with sinusoidal rotor shape (SynRM3) FEA results are compared with the conventional SynRM without cut-off (SynRM1) and SynRM with cut-off (SynRM2) on the q-Axis. The stator geometry of a 5.5 kW, 4-pole, 50-Hz, 8 A, conventional three-phase squirrel cage induction motor, with distributed double layer winding chorded by a single slot is used to model all three SynRMs.
