A motor control apparatus for an electric vehicle including a first motor to drive front wheels of the electric vehicle and a second motor to drive rear wheels of the electric vehicle, includes: a motor driving control unit that distributes a demand torque to be demanded for the electric vehicle and controls the first and second motors; a determination unit that counts time during which a driving torque distributed to one of the first and second motors is a reference torque, which is preset for the one of the first and second motors, or higher and determines whether the counted time is predetermined time or longer; and a driving torque distribution control unit that, when the counted time is the predetermined time or longer, reduces the driving torque distributed to the one of the first and second motors to below the reference torque and increases a driving torque distributed to the other of the first and second motors.
