Classification: CPC H | IPC H

Claim 4:
5. The motor control device according to claim 1, wherein in a case in which the controller is configured to be able to execute overmodulation control for the power converter on the basis of the voltage command values obtained through the arithmetic operation when the voltage command values fall within an overmodulation control region, the controller
controls the power converter on the basis of the voltage upper limit values when the voltage command values obtained through the arithmetic operations exceed the voltage upper limit values, and controls the power converter on the basis of the voltage lower limit values when the voltage command values obtained through the arithmetic operation are below the voltage lower limit values, and
corrects the predetermined range obtained through the arithmetic operation to be widened in consideration of differences between the voltage upper limit values or the voltage lower limit values and the voltage command values obtained through the arithmetic operation.
