Motor control device and motor control method

A motor control device that controls a motor including coil groups, the motor control device comprising processing circuitry, wherein

• the processing circuitry is configured to:
• calculate a current command value corresponding to torque that should be generated by the motor;
• divide the calculated current command value into individual current command values for the 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
• in response to the individual current command value for a first coil group of the coil groups being limited by a limit amount to a value that is smaller than a corresponding one of the upper limit values, increase the individual current command value for at least a second coil group of the coil groups by the limit amount.
