  4. Abstract:
  5. Multi-speed resolvers are used in the applications that need higher accuracy. However, they suffer from losing absolute position information. To overcome this challenge and improve the reliability of detecting position, using multi-turn resolvers is recommended. The conventional configuration of multi-turn resolver is using two individual resolvers on one shaft and into a common frame. Using such configuration needs special care on setting the distance between two resolvers. In this paper a new structure based on dual side configuration is proposed. The performance of the double sided resolver is analyzed and optimized using an analytical model based on magnetic equivalent circuit (MEC). Then, time stepping finite element method (FEM) is employed to verify the success of the new configuration and the applied optimization. Finally, the optimal resolver is built and tested. Experimental measurements confirm the success of the proposed sensor. IEEE
