This　paper　presents　a　new　compensation　method　about　speed　sensorless　vector　control　of　induction　motor(　IM).　The　proposed　method　calculates　a　direction　of　the　flux　by　reducing　the　q-axis　flux　to　zero　which　is　obtained　a　flux　observer.　In　order　to　stabilize　the　system　at　regenerating　operation,　a　new　compensation　method　is　proposed.　The　effectiveness　of　proposed　compensation　method　is　confirmed　by　stability　analysis　by　a　linear　model,　simulation　and　experimental　results.
