AC ROTATING MACHINE CONTROL DEVICE AND METHOD FOR CALCULATING MAGNETIC POLE POSITION CORRECTION AMOUNT

WIPO Patent Application WO/2016/038992

A1

The purpose of the present invention is to obtain an AC rotating machine control device capable of calculating, without connecting an AC rotating machine to a load device, a magnetic pole position correction amount for correcting a magnetic pole position error occurring during the application of rotating machine current. The AC rotating machine control device (10) of the present invention is characterized in that: a magnetic pole position correction amount calculation device (5) calculates a magnetic pole position correction amount (θc) on the basis of a detection current vector (Idt) detected when a voltage applying device (3) applies a voltage to an AC rotating machine (1) in response to a voltage command (voltage command vector (V1*), voltage command vector (V2*)) and of the voltage command, and stores the magnetic pole position correction amount (θc) made to correspond to the detection current vector (Idt) into a storage device (6); and a voltage vector command generation device (4) generates a normal operation voltage command on the basis of the detection current vector (Idt) detected by a current vector detection device (2) when normally operating the AC rotating machine (1) and the magnetic pole position correction amount (θc) corresponding to the detection current vector (Idt).
