Provided is a motor control device that realizes a high power drive and keeps a steering feeling having a good responsiveness with respect to an operation amount of a steering wheel like an electric power steering device while suppressing an input current to be equal to or lower than a predetermined value in response to a power source management as a vehicle. The motor control device of the invention includes an inverter which converts a DC input current from a DC voltage source into an AC current on the basis of a rotor phase of a motor and outputs the AC current. In a range in which an input current to the inverter does not exceed a predetermined upper limit while keeping a torque current, a maximum weak field current is calculated by a weak field current command calculation unit and is conducted.
