Abstract
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.
