Title:
ROTATING ELECTRIC MACHINE CONTROL DEVICE AND ROTATING ELECTRIC MACHINE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/179780
Kind Code:
A1
Abstract:
The present invention addresses the problem of reducing torque pulsation. The rotating electric machine control device according to the present invention is provided with: a sine-wave generation circuit for generating a sinusoidal signal corresponding to the magnetic pole position of the rotor of a rotating electric machine; a current command circuit for generating a current command on the basis of the sinusoidal signal and a torque command based on a speed command and actual speed information; and a current control circuit for controlling, on the basis of the current command and the current detection signal of the stator winding of the rotating electric machine, an inverter circuit interposed between the stator winding and a DC power supply to flow sinusoidal current through the stator winding. The current control circuit periodically changes the phase of the sinusoidal current when the rotating electric machine is driven at a predetermined torque and at a predetermined rotational speed.
