Provided is a vector control device for a permanent magnet synchronous motor driven. The device includes: a current command generation unit for generating a d-axis current command and q-axis current command from a given torque command; and a current control unit operating so that the motor current coincides with the current command. The current command generation unit includes: a d-axis basic current command generation unit for generating a first d-axis basic current command idl* by using the torque command; a limiter unit for inputting the current command idl* and outputting a value limited to below zero as a second d-axis basic current command id2*; a d-axis current command compensation unit for outputting the current command id2* corrected in accordance with the d-axis current command compensation value dV as a d-axis current command; and a q-axis current command generation unit for generating a q-axis current command from the d-axis current command. |
