Flux barrier and skew design optimisation of reluctance synchronous machines

In this paper an investigation into an alternative reluctance synchronous machine rotor flux barrier topology creation technique is presented. The technique investigated implements a high number of flux barrier variables with an alternative asymmetric rotor structure topology in combination with optimisation and finite element analysis. The investigation focuses on maximising average torque and minimising torque ripple in order to study the possibility of achieving acceptable torque ripple machine parameters without implementing rotor skew as torque ripple reduction technique. A further investigation into the effect of rotor skew on the proposed topology is conducted followed by the manufacturing of the proposed flux barrier prototype and testing.
