In this paper, an investigation into an alternative topology for reluctance synchronous machine rotor flux barriers is presented. The investigated topology employs a high number of flux barrier variables with an alternative asymmetric rotor structure. The focus in this paper is on maximizing average torque and minimizing torque ripple, using finite(More)
The relationship between the well known competitive torque density and less competitive power factor of reluctance synchronous machines is investigated. The study consists of a multi-objective design optimisation implementing a weighted factor optimisation technique. The investigation was carried out by implementing a complete machine model in the(More)
The relationship between the well-known competitive torque density and less-competitive power factor of reluctance synchronous machines (RSMs) is investigated in this study. The investigation was carried out by implementing a complete machine model in the optimization, with varying machine-pole number and flux-barrier number combinations. Furthermore, the(More)
In this paper, reluctance synchronous machines are designed and optimised to operate in the 5 MW power range for the implementation as wind generators. It is shown, when assuming no rotor deformation, that reluctance synchronous generators can be comparatively designed to operate in this power range with power factors higher than 0.8 achieved. In order to(More)
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(More)
