  4. Abstract:
  5. Resolvers are widely used in the control of industrial inverter driven motors. Among different types of resolvers, disk-type wound-rotor resolvers have superior performance under mechanical faults. However, the rotary transformer's (RT's) presence in the inner side of the resolver's core leads to additional radial length. To overcome this problem, disk-type wound-rotor resolver without RT's core has been proposed. However, the optimization using time stepping finite-element method (TSFEM) is time consuming due to 3-D structure of this resolver. Accordingly, in this paper, an analytical model based on the magnetic equivalent circuit is proposed for the design and optimization process. The results of the presented model are verified using 3-D TSFEM and experimental test on a prototype resolver. © 2001-2012 IEEE
