TLDR
In this paper, the performance of multiphase machines designed for operation with static power converters is investigated, where the winding distributions are intentionally rectangular to better accommodate the rectangular waveforms of solid-state inverters.Abstract:
The performance of multiphase machines designed for operation with static power converters is investigated. The winding distributions are intentionally rectangular to better accommodate the rectangular waveforms of solid-state inverters. Equations which define the transient as well as steady-state behavior, including the computation of all machine inductances, are derived. In deriving these equations the space harmonics are specifically included. Equations for calculation of terminal voltages and electromagnetic torque are modified to account for nonsinusoidal air-gap-flux distributions. A conventional three-phase induction motor including the effect of space harmonics is simulated. >read more
