Description
Summary:Future road vehicles will contain many controlled electrical drive systems not only used for traction, but also for safety-related chassis systems. Such electrical drives need to be highly reliable. Many state-of-the-art redundancy structures are not suitable for car applications due to high space requirement and/or degradation during post-fault operation. The aim is to provide an optimized fault-tolerant PMSM-machine design with minimum space requirement and low degradation. In this paper, a six-phase machine is used and after electromagnetic and thermal modeling and simulation, an approach is shown how to meet the aforementioned goals by optimizing the thermal post-fault-operation capability.
