  4. Abstract:
  5. Resolvers are widely used in high performance motion control of inverter-driven motors. Among different types of resolvers, axial flux wound-rotor (AFWR) resolvers have gained more attention due to their higher stability against static eccentricity. So, in this study the influence of stator and rotor winding arrangements on the accuracy of AFWR resolvers is presented. A single/two phase distributed, constant turn winding is considered for the rotor and the influence of short circuit damper winding of the rotor is investigated. For the stator, constant turn, distributed winding and variable turn, on-tooth winding is examined. Finally, it is shown that using variable turn on-tooth winding for the stator along with a damper winding for the rotor leads to the most accurate resolver. All the simulations are done by 3-dimensional time stepping finite element method (3-D TSFEM). And, experimental test on the prototype of the studied sensor is used to evaluate the simulation results. © 2018 IEEE
