Abstract: This paper presents the evaluation of performance indexes of a novel Synchronous Reluctance Motor (SynRM), which has an axially sinusoidal rotor lamination shape. The stator of a 5.5 kW, 4-pole, 50 Hz conventional three-phase squirrel cage induction motor, with distributed and chorded by one slot, double layer winding, is used for both standard and novel synchronous reluctance motors. Due to the nature of the sinusoidal rotor structure, the 3D Finite Element Analysis (FEA) is utilized to study the electromagnetic parameters of interests. The SynRM with sinusoidal rotor shape results are compared with the standard SynRM without cut-off on the q-axis. The FEA results are validated by means of practical measurements. From both FEA and measured results, it is evident that the novel SynRM enhances the performance indexes of interests such as torque density, torque ripple factor and efficiency.
