To suppress disturbance of phase current in compensation for a dead time.SOLUTION: A motor control device includes a phase voltage output unit that outputs voltage command values for the phases of an N-phase motor (N is an integer of 3 or more), a compensation unit that gives, to the voltage command values, a dead time compensation value for compensating a dead time in an inverter, and a change control unit that moderates a time change of the dead time compensation value in a time region where positive/negative switching of the dead time compensation value occurs.SELECTED DRAWING: Figure 6

    【課題】デッドタイム補償における相電流の乱れを抑制する。【解決手段】モータ制御装置は、N相モータ(Nは3以上の整数)の各相に対する電圧指令値を出力する相電圧出力部と、上記電圧指令値に、インバータのデッドタイムを補償するデッドタイム補償値を付与する補償部と、上記デッドタイム補償値の正負が切り替わる時間領域において、当該デッドタイム補償値の時間変化を緩やかにする変化制御部と、を備える。【選択図】 図6
