“…Various fault-tolerant strategies for PMSM drives have been proposed in the literature as well as different variations of them [58]. Six main strategies can be identified: two-phase motor operation (TPMO), four-leg inverter (FLI), Star point connected motors (SPCM), DC-Link midpoint connected (DMC), leg-redundant inverter (LRI), H-bridge inverter (HBI) and cascade inverter (CI).…”

“…Additionally, currents up to 1.73 times the phase current can circulate between the star point and the DC link midpoint. This current also causes the DC link midpoint voltage to fluctuate and must be regulated by the controller which complicates the control [58]. The topology can be modified to accommodate for switch faults by reconfiguring it to a B4 inverter [60].…”

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