The present invention provides a ball screw dual-motor power steering, which includes a steering shaft, a ball bearing structure, two motors, two housings, and two controllers. The steering shaft includes a screw rod portion and a gear rack portion, and the ball bearing structure is sleeved on the screw rod portion of the steering shaft. The two motors are respectively provided at both sides of the ball bearing structure, and each includes a rotor and a stator, and the steering shaft is disposed through the rotor and the stator, and the rotor is secured to the ball bearing structure, wherein each of the two of the controllers are electrically connected to the two motors respectively. Wherein, one of the two controllers control one of the two motors to drive the rotor to rotate the ball bearing structure, and the ball bearing structure drives the steering shaft to displace along its axial direction.
