Test characterization of a high performance fault tolerant permanenet magnet machine

摘要: It is well understood that an electric machine's output performance limited by its losses and thermal behavior. For novel prototype machines, hardware testing processes are important part of quantifying these parameters. some effective characterization may be accomplished using a series static simple prime-mover tests. The resulting data permits calibration loss- thermal-models. These can then used to predict on-load performance. Fault-tolerant machines based on single layer winding arrangements designed minimize interaction between windings or module-groups. This paper demonstrates that, for such machine, the measured during DC primer-mover tests infer both ‘healthy’ ‘faulted’ operating modes. Under faulted conditions total machine loss expected combination module-specific common losses, which directly deduced from discusses accuracy superposition when applied 180 kW multi-channel, fault-tolerant aerospace machine. From observations following healthy dynamometry tests, there exists close correlation full-load estimates made under discrete
