Electrical machines and drives, and their associated power electronics, are a key part of an industrialized society. Reliability is a major challenge in systems design, operation, and maintenance of these technologies. Unreliable systems drive up costs, so diagnostics and fault tolerance become important to help maintain the system and estimate its operational lifetime. Diagnosis and Fault Tolerance of Electrical Machines, Power Electronics and Drives describes techniques for fault analysis, diagnostics, condition monitoring methods, reconfiguration, remedial operating strategies and fault tolerance in electrical machines, power electronics and variable speed drives. It is a must-read for researchers in academia and industry, as well as for manufacturers and advanced students involved with electrical machines.
