Vector　control　theory　is　one　of　the　main　methods　to　drive　Permanent　Magnet　Synchronous　Motor　(PMSM).　In　this　paper,　according　to　the　requirements　of　the　real-time　control,　performance　expansibility　and　the　control　strategy　intellectual　property,　based　on　the　SOPC　design,　the　PMSM　controller　is　developed　to　implement　vector　control　algorithm　by　the　pure　hardware　circuit.　Circuit　simulation　and　experiment　results　have　shown　that　it　is　correct　and　effective.
