FEM-based analysis on the operation of three-phase induction motor connected to six-phase supply system: Part 2 — Study on fault-tolerance capability

摘要

Based on the fact that the three-phase induction machine proves higher performance under six-phase supply, which was demonstrated in Part 1 of the paper, this work investigates the fault-tolerance capability of the six-phase structure with asymmetrical configuration (30° phase shifting both for space and time conditions). It is taken into discussion the cut-off of one, two and three phases respectively. The study is carried through FEM simulations under steady-state and transient conditions.
