Abstract: Analyzed the principle of the traditional solution of the resolvers. It was high cost and had complex external circuitry, so introduced a triangle software solution of the resolvers based on LabVIEW. LabVIEW is good at data acquisition and waveform processing. The results of the special resolver angle module showed that the new method was effective. It met the requirements of realtime and highprecision, so the practicality of this solution would be wide.
