DOI: 10.1109/tpel.2023.3347300
Abstract: The parallel stator poles structure and concentrated field winding configuration of the doubly salient electromagnetic motor (DSEM) lead to the asymmetric three-phase flux paths and thus causing the significant d-axis and q-axis voltage harmonics. In… read more here.
