Abstract
An apparatus for estimating rotor position of a rotating machine having an even number of phase windings selects first and second phase position estimates developed in response to pulses applied to phase windings having associated phase profiles that are displaced at other than 180 electrical degrees and determines a rotor position estimate from the first and second phase position estimates.
