The parameter design and calculation for Axial-Flux resistance resolver

The parameter of the Axial-Flux resolver is difficult to be calculated for its complete magnetic structure. By using analytical method, the conclusion is got that the resistance of the reluctance resolver is varied by changing its electro-magnetic coupling area. At the same time, by selecting appropriate shape of the inclined ring of the rotor, the output sine and cosine signal of the EMF is optimized. In order to analyze the axial flux through the stator and the rotor, 3D transient FEM is used. The character of the EMF in signal windings is got at same time. The result of the FEM analysis is coinciding with supposing of the analytical method well and this will offer us the basic parameters for the further analysis in the future.
