Optimal Design and Experimental Validation of a Synchronous Reluctance Machine for Fault-Tolerant Applications

In this paper a dual-three phase synchronous reluctance machine is optimized for fault-tolerant applications. The main objective of such a design is improving the fault-tolerant capability by means of a proper motor geometry and winding arrangement paying attention to the torque density, torque ripple, mutual magnetic coupling and the maximum short circuit currents in several operating conditions. Finally, a prototype is manufactured and tested in order to validate the simulation predictions yielding good results.
