Fault Tolerant traction electric drives : reliability topologies and components design This concise book focuses on the reliability of traction electrical drives. The first chapter presents the Lz transform approach for the comparative analysis of the fault tolerance of multi motor electrical drives with multi phase traction motors. The second chapter then provides an estimate of the value of the operational availability and performance of a diesel–electric multi drive propulsion system while the third chapter introduces the concept of a more electric aircraft. Lastly the fourth chapter analyzes the requirements for multi phase permanent magnet motors applicable in various aircraft systems Reliability and Fault Tolerance Assessment of Multi Motor Electric Drives with Multi Phase Traction Motors Operational Availability Investigation of Multi Drive Electric Propulsion System of the Arctic Gas Tanker with Ice Class Arc7 Reliability Oriented Design of High Speed Multi Phase Electric Generator for the Aerospace Application Fault Tolerant Multi Phase Permanent Magnet Synchronous Motor for the More Electric Aircraft
