| description | The present invention relates to a driving apparatus for driving an electric motor, such as a synchronous motor or an induction motor, and more particularly to a driving apparatus which performs a vector control based on an output current of an inverter. The driving apparatus of the present invention includes an inverter (10), a current detector (12) configured to detect an output current of the inverter (10), and a vector controller (11) configured to transform the output current, detected by the current detector (12), into a torque current and a magnetization current and to control the torque current and the magnetization current. The vector controller (11) includes a target-output-voltage determination section (27) configured to determine a target output voltage from the torque current, the magnetization current, an angular velocity of the rotor, and motor constants, and a target-magnetization-current determination section (26) configured to determine a magnetization-current command value based on a deviation between the torque-voltage command value and the target output voltage. |
