Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/106095
Kind Code:
A1
Abstract:
Provided is a motor control device that, in the case where each system is provided with a DC power supply, can suppress the occurrence of a torque difference between systems even when a DC voltage difference occurs between the systems. The present invention is a motor control device wherein: when a first controller 9a determines that a first DC voltage (Vdc1) is higher than a second DC voltage (Vdc2), the first controller 9a performs control so that a first q-axis detected current value (Iq1_det) approaches a second q-axis detected current value (Iq2_det) or a second q-axis current command value (Iq2_ref) acquired from a second controller (9b); and when the second controller (9b) determines that the second DC voltage (Vdc2) is higher than the first DC voltage (Vdc1), the second controller (9b) performs control so that the second q-axis detected current value (Iq2_det) approaches the first q-axis detected current value (Iq1_det) or a first q-axis current command value (Iq1_ref) acquired from the first controller (9a).
