Optimization of Absolute Variable Reluctance Resolver with Taguchi and FEM
Longfei Xiao, Chao Bi · 2019
As angle sensors, Variable Reluctance (VR) resolvers can be divided into incremental and absolute types (IVR and AVR). Both IVR and AVR resolvers have been widely used in many drive systems. However, high performance AVR resolvers are difficult to design as the effects of rotor shape is very complicated. In this paper, Taguchi method combines with FEM Finite Element Method (FEM) is used to optimize the accuracy of AVR resolver by adjusting the rotor shape. The optimization time can thus be reduced significantly.
