Premium (IEC IE3 Class) efficiency Motors are now mandatory in North America. Super-
Premium (IEC IE4 Class) and IE5 Ultra-Premium efficiency classes are defined in the …

An optimally designed ferrite permanent magnet (PM)-assisted synchronous reluctance
machine (PMaSynRM) is presented to demonstrate its feasibility in electric vehicle …

In recent years the synchronous reluctance machines (SynRMs) have received much
attention. They have some good features such as high torque density, high reliability and …

The complex rotor structure of the synchronous reluctance machine (SynRM) is analyzed in
this paper. Three macroscopic design parameters are introduced: insulation ratios in the d …

This paper proposes a sensorless direct flux vector control scheme for synchronous
reluctance motor drives. Torque is controlled at constant switching frequency, via the closed …

This paper theoretically introduces and develops a new operation diagram (OPD) and
parameter estimator for the synchronous reluctance machine (SynRM). The OPD …

This thesis is comprehensively dedicated to the theoretical and experimental reevaluation of
the Synchronous Reluctance Machine (SynRM). The thesis critically examines the important …

Although three-phase induction motors are the most common motor type in industry, a
growing interest has arisen in emerging electric motor technologies like synchronous …

A criteria to design the rotor of multi flux-barrier synchronous reluctance (REL) machines is
proposed. In particular, the focus will be on the proper design of flux-barriers geometry. An …

The rotor structure of synchronous reluctance machines (SynRel) is conventionally retained
mechanically by iron ribs. In this paper, a novel structure for high-speed synchronous …
