Performance indexes' evaluation of a NSynRM with sinusoidal rotor shape.

This study presents the evaluation of performance indexes of a novel synchronous reluctance motor (NSynRM) that 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 NSynRMs. Owing to the nature of the sinusoidal rotor structure, the three‐dimensional finite element analysis (FEA) is utilised to study the electromagnetic parameters of interests. The NSynRM with sinusoidal rotor shape results is compared with the standard SynRM without cut‐off on the q‐axis. The FEA results are validated by means of practical measurements.
