Comparison of MTPA and Minimum Loss Control for Tooth Coil Winding PMSM Considering PM and Inverter Losses
Paper in proceedings, 2019

This paper presents a comparison between MTPA and minimum loss control including the PM and inverter losses for a tooth coil winding PMSM. Tooth coil winding machines can have significant iron and PM losses due to space harmonics generated by the stator winding distribution. Both these loss contributions should be taken into account when evaluating the control strategy. Depending on the machine design and in particular the magnetic and electric loading, the advantage of using a minimum loss control can vary. Two case studies for an electric vehicle application are presented and the advantage of using the minimum loss control is quantified and analyzed for different drive cycles showing energy savings up to 6% on low speed drive-cycles and up to 13% for high speed drive-cycles.
