Abstract

Wound-Rotor (WR) resolvers are the most commercially used resolvers in industrial applications. In this regard, the present study evaluates the effect of different winding arrangements on the accuracy of WR resolvers. To this end, three windings were proposed for the stator of the resolver containing on-tooth overlapping winding, distributed lap winding, and distributed concentric winding. Those windings were also applied to the rotor. All the rotor windings were assumed to be single- and two-phased. In addition, the effect of damper winding was also evaluated in this study. The analysis was done using time-stepping finite element method, and the most accurate resolver was built and tested. Close agreement between the results from experimental measurements and finite element confirms the obtained results.
