Varying Magnetization Orientation for Permanent-Magnet Volume Reduction in Machines

We present an enhanced version of a method to minimize the amount of permanent-magnet (PM) material required to create a certain flux linkage in the stator winding of a PM machine. The enhanced version obtains the distribution of the factor inside the PM; identifies the areas inside the PM volume where the orientation of magnetization may be modified, so as to further increase the amount of no-...

Modeling of Iron Losses of Permanent-Magnet Synchronous Motors

Permanent-magnet (PM) motors offer potential energy savings as compared with induction motors because of the virtual elimination of rotor loss and the reduction of stator loss from operation near unity power factor. In PM machines, iron losses form a significant fraction of the total loss partly due to the nonsinusoidal flux density distribution. Design optimization therefore requires good mean...

Maximum Efficiency per Torque Control of Permanent-Magnet Synchronous Machines

Abstract: High-efficiency permanent-magnet synchronous machine (PMSM) drive systems need not only optimally designed motors but also efficiency-oriented control strategies. However, the existing control strategies only focus on partial loss optimization. This paper proposes a novel analytic loss model of PMSM in either sine-wave pulse-width modulation (SPWM) or space vector pulse width modulati...
