Original Abstract Submitted
A motor control device controls energization to a motor having two three-phase winding sets configured such that their electrical angle phase difference is ±(φ+120×n)° (0<φo≤60°, n is an integer). A current redistribution section of a current command value calculation unit executes “current redistribution process” when a predetermined condition is satisfied. In the current redistribution process, the current redistribution section calculates a specific maximum current value, which is the maximum value of the absolute values of the three-phase current command values in each system, for each electrical angle. The current redistribution section redistributes the current command values of the two systems so that a ratio between I1_max(θ)×(1+α(θ)), which is the specific maximum current value of the first system after the redistribution, and I2_max(θ)×(1−α(θ)), which is the specific maximum current value of the second system after the redistribution, approaches a predetermined target ratio.
