Title:
ELECTRIC APPARATUS DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/137372
Kind Code:
A1
Abstract:
The present invention relates to a drive device that drives electric apparatus such as synchronous motors and induction motors, and in particular relates to a drive device that performs a vector control on the basis of an inverter output current. The drive device of the present invention is provided with an inverter (10), a current detector (12) that detects the output current of the inverter (10), and a vector controller (11) that converts output current detected by the current detector (12) to torque current and magnetization current, and controls the torque current and magnetization current. The vector controller (11) is equipped with: a target output voltage determiner (27) that determines a target output voltage from the torque current, the magnetization current, a rotor angle speed, and a motor constant; and a target magnetization current determiner (26) that determines a magnetization current command value on the basis of the deviation between a torque voltage command value and the target output voltage.
