Effects of the Rotor Mechanical Offset Angle on the Electromagnetic Performance of Dual Stator Wound-Field Flux Switching Machines

This study is concerned with the effect of the rotor mechanical offset (MO) angle on the electromagnetic performance of dual stator wound-field flux switching machines (DSWFFSMs). The focus is to find the optimum initial rotor position so that control of the machine can be facilitated. Using finite element analysis (FEA) and based on a cocktail of simulations, key electromagnetic performance indices such as average torque, torque ripple, power factor and efficiency are studied under dynamic on-load state, with the optimum MO angle established at 8°. The experimental test prototype has been developed and the test results are promised future extended paper version.
