An AFS-MDPS(Active Front Steering-Motor Driven Power Steering) integrating actuator system is provided to lower steering gear ratio at high speed by driving a plurality of helical gears and magnetic clutches according to vehicle speed. An AFS-MDPS(Active Front Steering-Motor Driven Power Steering) integrating actuator system comprises a steering shaft(10), a plurality of helical gears(21~24), a number of magnetic clutches(31~34), a variable lined helical gear(40), and an integrating motor(50). The helical gears and the magnetic clutches make a pair on the steering shaft. The variable lined helical gear is in contact with each helical gear. The integrating motor drives the variable lined helical gear. The AFS-MDPS integrating actuator system reduces operation of a steering wheel, allows a driver to operate the steering wheel less, when parking or driving a vehicle, and obtains a steering gear ratio suitable to high speed. The AFS-MDPS integrating actuator system changes the steering gear ratio according to vehicle speed.
