Abstract
An electro-mechanical actuator for generating an axial actuation force is provided. The electro-mechanical actuator includes an electric machine having a stator () and a rotor (). The electro-mechanical actuator also includes a spindle drive with a rotary element () and with an element that is movable in a translatory manner. A rotation of the rotary element () may result in a translatory motion of the element that is movable in a translatory manner. The rotor () and the rotary element () of the spindle drive are coupled to each other in a circumferential direction (U) such that a rotation of the rotor () results in a rotation of the rotary element () of the spindle drive (). A rotational play () is formed between the rotor () and the rotary element () of the spindle drive in the circumferential direction (U).
