A motor control system for a commercial vehicle having an electric axle includes: first and second motors disposed in a rear-wheel electric axle; an accelerator position sensor for detecting a degree to which an accelerator is depressed; a wheel speed sensor detecting a wheel speed change; and a controller determining a driver's required torque on the basis of detection signals of the accelerator position sensor and the wheel speed sensor and then controlling a torque of the first motor in such a manner as to approach target torque for satisfying the driver's required torque and at the same time either controlling either a torque of the second motor to a level that compensates for a torque error of the first motor or controlling the torque of the first motor and the torque of the second motor at alternating fixed duty ratios.
