Abstract / Hauptanspruch
A resolver system includes a rotatable primary winding (18), a secondary winding (20) fixed relative to the primary winding, and an analog-to-digital converter (28) electrically connected to the secondary winding. A control module (100) is operatively connected to analog-to-digital converter and is responsive to instructions to apply an excitation voltage with an oscillating waveform to the primary winding, induce a secondary voltage using the secondary winding using the excitation voltage, and acquire a plurality of voltage measurements from the secondary winding separated by a time interval corresponding to π/3 of the excitation voltage oscillating waveform.
