ABSTRACT:
A variable reluctance resolver wherein the sine and cosine values are processed to obtain digital values for position with an accuracy similar to that of a conventional resolver. The variable reluctance resolver is driven at a constant speed and the incremental digital values are recorded and processed to extract the fundamental through a Fourier transform. The Fourier transform of the fundamental is compared to the original values from the variable reluctance resolver to provide a look up table of correction values.
