Loss and efficiency comparisons of four type SynRMs using Preisach models and experimental verification

This presentation discusses loss and efficiency evaluations of 4-type synchronous reluctance motors (SynRMs) with permanent-magnet-assisted (PMA), non-PMA and both concentrated winding (CW) and distributed winding (DW) by the finite element method (FEM) and by experiment. The performance characteristic is compared according to the stator and rotor types in the SynRMs. In addition, the efficiency evaluation is also compared, including hysteresis loss, copper loss and other losses, on the basis of the rated load condition.
