Review of Fault Tolerant Multi-Motor Drive Topologies for Automotive Applications

With vehicle electrification and employment of X-by-wire technology, mechanical systems are being replaced by motor drives which improve the efficiency performance vehicular systems. However, have a lower power density reliability compared to solutions. Multi-motor potential mitigating both these drawbacks. In this paper, state-of-the-art review multi-motor their application is carried out. Firstly, case in automotive applications laid out presenting different comprising multiple motors. Secondly, drive topologies with improved density, fault tolerance capabilities thoroughly analyzed. Finally, assessed context applications. The assessment verifies that allow for tolerant cost-effective solutions suitable
