The purpose of the present invention is not only to reduce ripple current but also to improve operation efficiency by reducing heat generation. When n is defined as an integer of 2 or more, a motor control device of the present invention drives n sets of windings by n sets of inverters. The motor control device is characterized in that when said n sets of inverters output high power, at least one or more of said n sets of inverters are set to have an output duty cycle of 100%.
