Effect of Permanent Magnet Rotor Design on PMSM Properties
Abstract
The paper is focused on the permanentmagnet location and shape investigation in PMSM. At first,
the real PMSM has been modeled by means of FEM which
has been verified by experiments. Next step was a creating
of two new models with different position of PM: one with
surface mounted PM and other one with inset PM. The PM
volume and quality have been in all models kept constant .
The main goal of this paper is to investigate the influence of
the PM design on PMSM properties such as torque ripple,
maximum torque, EMF, stator current and winding losses.
The investigation has shown, that PM surface design can
improve PMSM properties.
