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.

This book focuses on one of the most important aspects of electrical propulsion systems - the creation of highly reliable safety-critical traction electrical drives. It discusses the methods and models for analysis and optimization of reliability and fault tolerance indices, based on which, it proposes and assesses methods for improving the availability, fault tolerance and performance of traction electric drives.

This book provides a comprehensive assessment and presentation of various feasible application of electric propulsion system, considering their weight, volume, reliability, and fault tolerance. The results of feasibility analysis can be used today or in the near future for development of electric propulsion system for the ships, planes, helicopters, and spacecrafts. To solve the above task, new theoretical approaches are applied, including combined random process methods, the Lz-transform technique for multistate systems, and statistical data processing.
