ABSTRACT:
An electrically operated drive controller includes first and second electric current command value calculation means which calculate first and second electric current command values based on a target value of torque of an electrically operated machine. The controller also includes a voltage command value calculation processing means which calculates a voltage command value based on the first and second electric current command values and an adjusting value calculation processing means for calculating an adjusting value of the first electric current command value and for performing weak field control based on the voltage command value. The first electric current command value calculation processor adjusts the first electric current command value based on the adjusting value. The second electric current command value calculation processor adjusts the second electric current command value based on the adjusted first electric current command value.
