Abstract
In this paper, fault tolerant topologies based on permanent magnet synchronous machines (PMSM) are presented. A numerical model for the simulation of the operational behaviour under normal and fault conditions is developed and validated by test bench measurements. For different fault tolerant topologies, control strategies for normal and post-fault operation are presented and validated by measurements and simulations. In post-fault operation, the presented control-strategies allow the compensation of braking torques and to avoid overvoltages at the machine terminals. In normal operation, the additional degrees of freedom are utilized to improve operational behaviour in various aspects.
