Abstract
To provide a motor controller which can suppress occurrence of a torque difference between systems, even if a DC voltage difference occurs between systems, in the case where each system is provided with a DC power source. A motor controller is provided with a first controller that controls so that the first q-axis current detection value approaches the second q-axis current detection value or the second q-axis current command value obtained from the second controller, when determining that the first DC voltage is higher than the second DC voltage; and a second controller that controls so that the second q-axis current detection value approaches the first q-axis current detection value or the first q-axis current command value obtained from the first controller, when determining that the second DC voltage is higher than the first DC voltage.
