A motor control device 100 includes a motor 10, a control device 40, and a motor drive circuit 50. The motor 10 includes a motor rotor 20, a motor stator 30, and a plurality of coil groups divided into a first coil group G1 and a second coil group G2 of at least two systems for each of three phases, and configured to excite a stator core 31 by three-phase alternating currents. In the motor drive circuit 50, a first motor drive circuit 50A supplies a three-phase AC first motor drive current to the first coil group G1 based on a command value, and a second motor drive circuit 50A 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 G2.
