Abstract
A motorized spindle drive for an actuator, particularly for an aerodynamically effective surface of an aircraft, may have a spindle and a motor that comprises a mechanical transmission element engaging the spindle in order to drive said spindle and causing a relative movement in the axial direction between the spindle and the motor and that is connected to an element that is fixed in place relative to the motion of the spindle, said element absorbing the torque of the motor. According to the invention, the bearing absorbing the torque of the motor comprises a detachable coupling that detaches upon a predetermined torque being exceeded and releases the motor in the sense of a free movement in the axial direction of the spindle relative to the fixed element.
