An optimization approach of rotor contour for variable reluctance resolver

An effective approach for optimizing the rotor contour variable reluctance (VR) resolver is presented. Using this approach, procedure divided into two parts: establishment of initial shape curve, and then computation optimization. In order to simplify process former, a function constructed. And latter carried out by Taguchi optimization method finite element (FEM). example 3–10 VR used present optimization, testing results confirmed effectivity approach.
