Title:
ELECTRIC MOTOR DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/029715
Kind Code:
A1
Abstract:
A vector control unit (11) is provided with a torque voltage control unit (21) for determining a torque voltage command value on the basis of the deviation between the torque current command value and the torque current, a magnetizing voltage control unit (22) for determining the magnetizing voltage command value on the basis of the deviation of the magnetizing current command value and the magnetizing current, a target magnetizing current determination unit (26) for determining a magnetizing current command value on the basis of the deviation between the output voltage of an inverter (10) and the target output voltage, and a target output voltage determination unit (27) for determining the target output voltage. The target output voltage determination unit (27) stores a V/ω pattern showing the relation between target output voltage and angular velocity, and determines the target output voltage from the angular velocity in accordance with said V/ω pattern.
