Abstract
An actuator for the actuation of at least one movable member of a motor vehicle transmission. The actuator includes a housing, at least one electric motor having a stator and a rotor mounted on a rotor shaft extending along an axis X1, a motor pinion fixed to the opposite end of the shaft from the rotor, a circuit board for supplying power to the stator and controlling the electric motor, and a reduction mechanism driven by the motor pinion. The housing defines a first volume in which the electric motor and the circuit board are received. The circuit board is located axially along the axis X1 between the electric motor and the motor pinion. The actuator further includes a cover defining a second volume in which the reduction mechanism is received, the housing and the cover each have guides for guiding the reduction mechanism.
