Abstract
An electromechanical actuator for rack-and-pinion steering includes a stator, rotor, and electronic system. The electronic system includes at least one first electronic sub-system and a second electronic subsystem, each operatively connected to the stator and the rotor. The at least one first electronic sub-system is arranged at least on a first circuit carrier plane and a second circuit carrier plane, and includes a first power output stage, a first control unit, and a first rotor position sensor arrangement. The second electronic sub-system is arranged at least on the first circuit carrier plane and a third circuit carrier plane, and includes a second power output stage, a second control unit, and a second rotor position sensor arrangement. The first, second and third circuit carrier planes are arranged perpendicular to an axis of rotation of the rotor, and are spaced apart from each other along the axis of rotation.
