Abstract (en)

[origin: WO0014696A1] A digital signal processor (DSP) (18, 74) for closed loop velocity or position control receives sine winding output signals and cosine winding output signals from a resolver (10, 73), digitizes the signals and outputs quadrature encoded signals to an excitation circuit (16, 77). The excitation circuit (16, 77) is connected to an excitation winding in the resolver (10, 73) to provide signals for driving the resolver (10, 73).
