High Accuracy Position Measuring System Based on AD2S80A for Permanent Magnet Synchronous Motor

The resolver to digital converter AD2S80A and the connection of its peripheral circuit were introduced, the interface circuit between AD2S80A and DSP TMS320F240 was designed, the high accuracy position measuring system based on AD2S80A for permanent magnet synchronous motor (PMSM) was implemented, the software and hardware of the system were presented. The actual results show that the system is featured by its high accuracy, small size, strong antijamming capability, flexible and handy in operation.
