In safety critical aerospace applications, fault tolerant drives can help reach the necessary system reliability levels without replicating the entire drive system and thus minimizing the overall system weight. Machine selection and design for fault tolerance has to be considered at an early stage to ensure optimal performance at system level. Permanent magnet Flux Switching Machines have the distinct...
Fractional-slot concentrated-winding (FSCW) synchronous permanent magnet (PM) machines have been gaining interest over the last few years. This is mainly due to the several advantages that this type of windings provides. These include high-power density, high efficiency, short end turns, high slot fill factor particularly when coupled with segmented stator structures, low cogging torque, flux-weakening...
Flux-switching permanent magnet (FSPM) brushless machines have emerged as an attractive machine type by virtue of their high torque densities, simple and robust rotor structure and the fact that permanent magnets and coils are both located on the stator. Both 2D and 3D finite element analyses (FEA) are employed to compare the performance of a standard topology with three modular, fault-tolerant designs...
