| 摘要 | A control device for an AC rotating machine includes a voltage command calculation means (1) that calculates voltage commands on rotation two axes and a voltage applying means (2) that applies a voltage to an AC rotating machine (3), based on voltage commands on the rotation two axes outputted by the voltage command calculation means (1); the voltage command calculation means (1) calculates first-axis and second-axis voltage commands on the rotation two axes and reduces the limit value of the second-axis voltage command in proportion to the squared first-axis voltage command. | ||
