Abstract: Actuator for automotive applications, comprising a main body that houses a motor, a transmission, a control shaft, kinematically connected to the motor by the transmission. The control shaft extends from a first transmission end, connected to the transmission, to a second operating end operatively connected to a user device. The control shaft is controlled in a reciprocating linear motion along an axial direction (Y-Y) by the transmission which transforms a rotation movement along a drive axis (X-X) of the motor into a translation movement of the control shaft along said axial direction (Y-Y). The motor and the control shaft are oriented so that the drive axis (X-X) and the axial direction (Y-Y) are perpendicular or parallel and spaced apart from each other.
