Abstract
There is provided a motor control device for controlling a motor including plural sets of windings, which is configured so that, when a fault detection means detects a fault, inverters in the normal side other than in the fault side are continued to be controlled by normal-time current control means and further, inverters in the fault side are continued to be controlled by fault-time voltage commands generated by a fault-time current control means configured with a fault-time normal-side command generator and a fault-time fault-side command generator, so as to emphasis a torque ripple of the motor when a winding fault of the motor or an inverter fault occurs, to thereby cause a user to surely recognize the fault.
