FEM-based analysis on the operation of three-phase induction motor connected to six-phase supply system: Part 1 — Operation under healthy conditions

Abstract

The paper presents a comparative analysis of a three-phase induction motor that operates connected to the industrial supply system and separately to a six-phase supply source, as well. The design of the electric machine is made in such a way to fit for both situations. The six-phase supply, which is composed of two distinct three-phase systems, was configured for two cases: 30° and 60° phase shifting between the systems, respectively. The analysis is based on FEM simulations under steady-state and transient conditions.
