description	To surely increase a maximum rotation speed of a motor in a weakening magnetic flux control.SOLUTION: When performing weakening magnetic flux control of a motor 3, based on drive current values Ia0 and Ib0, a rotation angle θ0 and a rotation speed ω0 in a case where the motor 3 is in a first drive state and drive current values Ia1 and Ib1, a rotation angle θ1 and a rotation speed ω1 in a case where the motor 3 is in a second drive state different from the first drive state, a motor drive control device 10 calculates parameters representing characteristics of the motor 3 and generates a drive control signal Sd based on the parameters.SELECTED DRAWING: Figure 2 【課題】弱め磁束制御において、モータの最大回転速度を確実に向上させる。【解決手段】モータ駆動制御装置１０は、モータ３の弱め磁束制御を行う場合に、モータ３が第１駆動状態であるときの駆動電流値Ｉａ０，Ｉｂ０、回転角度θ０、および回転速度ω０と、モータ３が第１駆動状態と異なる第２駆動状態であるときの駆動電流値Ｉａ１，Ｉｂ１、回転角度θ１、および回転速度ω１とに基づいて、モータ３の特性を表すパラメータを算出し、当該パラメータに基づいて駆動制御信号Ｓｄを生成することを特徴とする。【選択図】図２
