Abstract:
The invention relates to an electromechanical power steering system with a ball screw drive (1), having: a hollow shaft motor with a stator (3) which is secured to the housing and a rotatably mounted rotor (4) which is arranged coaxially with a longitudinal axis (2) and is drivingly connected to a hollow shaft (7), a ball screw nut (13) which is arranged coaxially with the longitudinal axis (2) and drives a ball screw spindle (20) via balls (21), the rotor (4) driving the ball screw nut (13) via a reduction gear.
