  4. Abstract:
  5. Multi-turn resolvers are proposed to be used in high accuracy, high-reliability applications that need to have the benefits of absolute measurement and high accuracy, simultaneously. In this paper, the influence of different arrangements of rotary transformer (RT) and resolvers' core on the accuracy of a multi-turn wound rotor (WR) resolver is discussed. Then, an optimal configuration with the aim of reducing the total cost, and the total volume of the sensor is proposed. All the analysis is done using 3-D time-variant finite element method (3-D TVFEM) and the optimal structure is built for experimental tests. Finally, experimental measurements are employed to verify the simulation results. © 2001-2012 IEEE
