Abstract

Recently synchronous reluctance motors (SynRMs) have attracted interest because of need to conserve energy and reduce unstable magnet costs The stator in a SynRM is fundamentally the same as that in an in-duction machine with three-phase windings that produce a sinusoidal ex-citation Magnetomotive force wave at the air gap The most critical per-formance parameters of an SynRM depend on the synchronous inductance ratio or saliency ratio Ld/Lq and the difference between Ld and Lq In this thesis a high efficient SynRM producing a low torque ripple is presented The research was divided into two parts First the dimension effect of SynRMs was investigated Using four dimensions of stators and designing the rotor by employing the determined design process the relationship between dimension and saliency ratio was determined Second the SynRM design was investigated and a design process was established by analyzing the rotor structure of existing induction motor stators and conducting finite element analysis simulations Experimental studies of the final design model were compared with the analytical results
