A　method　of　induction　motor　modeling　is　proposed　for　the　study　of　voltage　flicker　transfer.　Based　on　the　voltage　equations,　electromagnetic　torque　equations　and　basic　motion　equations,　the　dynamic　phasor　method　is　applied　to　establish　the　dynamic　phasor　model　of　the　three-phase　induction　motor　with　fluctuant　source　voltage.　The　quantitative　calculation　of　stator　current　is　realized　and　the　influences　of　induction　motor　parameters　on　fluctuant　stator　current　and　rotor　mechanical　angular　velocity　are　analyzed.　The　quantitative　calculation　of　induction　motor　voltage　is　realized　with　the　stator　current　calculation　formula.　The　influence　of　motor-type　load　on　voltage　flicker　transfer　is　studied　by　comparing　the　flicker　frequency　components　of　RMS　values　between　source　voltage　and　motor　voltage,　and　the　frequency　characteristics　of　flicker　transfer　coefficient　are　presented.　Results　show　that　the　induction　motor　restrains　the　flicker　at　most　flicker　frequencies.　The　correctness　of　theoretical　analysis　is　verified　by　simulation.
