Advantageously, the external diameter of the housing of the electronic control unit 15 is less than the internal diameter of the casing 17, so that the housing can be inserted into the casing 17, during the assembly of the electromechanical actuator 11. In a first case, the housing of the electronic control unit 15 may comprise two half-shells configured to cooperate together, in particular in the assembled configuration of the electronic control unit 15. In the assembled configuration of the electromechanical actuator 11, the two half-shells are assembled together, so as to define a junction plane extending in a direction parallel to the axis of rotation X. Advantageously, at least one of the two half-shells forming the housing comprises elements for positioning and fixing the first electronic card 15a, in particular the first printed circuit board 40a, in particular in the assembled configuration of the electronic control unit 15. In a second case, the housing of the electronic control unit 15 may comprise one or more sections, the or each section being made in the form of a hollow tube. The or each section is configured to house or receive, in other words houses or receives, the first electronic card 15a, in particularly in the assembled configuration of the electronic control unit 15. In such a case, the or each section of the housing comprises a first groove and a second groove. Furthermore, the first and second grooves are configured to hold in position, in other words hold in position, the first electronic card 15a, in particular the first printed circuit board 40a, inside the housing, particularly in the assembled configuration of the electronic control unit 15.

Furthermore, the embodiments and variations contemplated may be combined to generate new embodiments of the invention, without departing from the scope of the invention defined by the claims.
