Abstract
A motor control device includes processing circuitry configured to calculate a current command value corresponding to torque that should be generated by a motor, divide the calculated current command value into individual current command values for coil groups, control power feeding to the coil groups independently for each of the coil groups based on a corresponding one of the individual current command values, set, for each one of the coil groups, an upper limit value of a corresponding one of the individual current command values and, when the individual current command value for any one of the coil groups is limited to a value that is smaller than a corresponding one of the upper limit values, supplement an amount limited in the individual current command value by increasing the individual current command value for at least a remaining one of the coil groups.
