Metamodel-based Optimization of Synchronous Reluctance Motor Rotor

The optimum design of a magnetic system depends on different factors, attributable to the operation of the electromagnetic device. This research provides the optimization technique part that gives mathematically proven solution of the optimal rotor design of a synchronous reluctance machine with transversally laminated anisotropy. Current work proposes a resource-saving technique for shape optimization of the rotor by using metamodels in the form of local polynomial approximations. The optimal design results were obtained on the basis on proposed shape optimization method and were confirmed by finite element analyses and physical experiment. The object of investigation is synchronous reluctance motor based on modified 1,1 kW W21 WEG induction motor stator.
