Abstract
To provide an AC motor control device that drives and controls an AC motor using voltage phase control, and is capable of speeding up the overall response while suppressing reverse current response.SOLUTION: An AC motor control device converts DC power into AC power on the basis of a voltage phase command output from a voltage phase control unit and outputs the AC power to an AC motor, and the voltage phase control unit includes a change amount limiting unit that limits the amount of change in the voltage phase.SELECTED DRAWING: Figure 2
