Abstract:
An electromechanical power steering system with a ball screw drive may include a hollow shaft motor with a stator secured to the housing and a rotatably mounted rotor arranged coaxially with a longitudinal axis of, and which may be drivingly connected to, a hollow shaft. The system may further include a ball screw nut arranged coaxially with the longitudinal axis, and which may drive a ball screw spindle via balls. The rotor may drive the ball screw nut via a reduction gear.
