Abstract

The reluctance changing principle of resolver is divided into two kinds: one is varying reluctance through coupling area and the other is the air gap. The mechanical eccentricity makes much more influence on the precision of the one pair pole reluctance resolver. In this article, one pair pole axial flux reluctance resolver with new magnetic structure is put forward, which has the compensating character inside its two side air gap. The prototype has both the exciting windings and signal windings in its stator, which are vertical to each other. There is no winding in its rotor and one inclined ring is set in it. The character of the EMF in signal windings is got using FEM. At the same time, one 4-pole reluctance resolver's zero error analysis is put forward by using FEM. 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.
