Multiphase machines used in electric vehicles propulsion

Abstract

Multi-phase (more than three-phase) motor drive systems have attracted much attention in recent years due to some inherent advantages which they offer when compared to the three-phase counterpart. Presently the grid power available is only limited to three-phase so the supply to multi-phase motors is invariably given from power electronic converters. For applications operating with electric cars, multiphase system could satisfy potential demand for electric drive systems of power, which are both robust and energy efficient. The paper presents the modeling and simulations of an induction motor with 3 and 5 phases.
