A Comprehensive Design Approach to Minimize Position Error in Variable Reluctance Resolvers

초록

In variable reluctance (VR) resolvers, harmonic components in the induced voltage across the secondary windings are critical to the accuracy of position sensing. Reducing inaccuracy requires precise design of stator windings, sensor geometry, and configurations. To reduce angle errors in VR resolvers, a systematic design method is presented in this paper. Finite element analysis (FEA) is used to examine the effects of changes in the stator windings, rotor surface geometry, and stator core geometry. Finally, an efficient design process is introduced that can minimize position errors using a genetic algorithm-based optimization algorithm.
