On the Fault-Tolerance of Permanent Magnet Synchronous Machines and Drives Used in Hybrid Vehicle Application.

The paper presents a study of the fault tolerance problem on three types of electrical machines and drives used in hybrid vehicles. Three types of faults and the tolerance to faults is analyzed on these machines: material damage due to lack of remanence in the permanent magnets, construction fault and the effect of losing the phases of the machine or of the legs of the inverter used to drive the machine. The study presented in this paper is evaluated numerically and experimentally. [ABSTRACT FROM AUTHOR]
