An 8X-VR resolver is a variable reluctance type resolver. Clarification of relationship between the rotor eccentricity and the angle determination is required in order to improve variation of a revolution angle determination due to the eccentricity of the rotor. Effects of the eccentricity are predicted by means of 2D finite element analysis in various gap length models. Predicted relative electrical angle errors due to the rotor eccentricity gives good approximation of measured values. Amplitude variation of error distribution shows tendency to remain stable at rotor eccentricity longer than 0.08 mm. Spectrum analysis of output signals describes that the amplitude differences of 2nd, 3rd and 4th harmonic components vary wider than those of other harmonic components. And multivariate analysis indicates that the gap length has a high correlation with amplitude of harmonic components.
