  4. Abstract:
  5. Resolver, as an electromagnetic sensor, is widely used in different industrial applications such as servo motor feedback applications because of its reliable performance in the presence of undesired external factors in a harsh environment. Among different types of resolvers, variable reluctance (VR) resolvers draw attention due to their robust structure with a winding-less solid rotor and low-cost manufacturing. In this article, analytical modeling based on the magnetic equivalent circuit (MEC) is employed to investigate the output signals of the proposed toroidal winding arrangements for VR resolver with a 5-X rotor. Time-stepping finite element analysis (TSFEA) is used for all the simulations to achieve a satisfactory precision in analyzing the performance of the proposed VR resolver. Eventually, the results of the analytical model and TSFEM are both verified with an experimental test on the prototype resolver. © 2001-2012 IEEE
