Abstract: a motor control device controls energization to a motor having two three-phase winding sets configured such that their electrical angle phase difference is �(�+120�n)� (0<�o≤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(�)�(1+�(�)), which is the specific maximum current value of the first system after the redistribution, and i2_max(�)�(1−�(�)), which is the specific maximum current value of the second system after the redistribution, approaches a predetermined target ratio.
