A motor control device includes a motor, a control device, and a motor drive circuit. The motor includes a motor rotor, a motor stator, and a plurality of coil groups divided into a first coil group and a second coil group of at least two systems for each of three phases, and configured to excite a stator core by three-phase alternating currents. In the motor drive circuit, a first motor drive circuit supplies a three-phase AC first motor drive current to the first coil group based on a command value, and a second motor drive circuit supplies a three-phase AC second motor drive current having a phase difference from a phase of the first motor drive current, to the second coil group.
