An electromechanical actuator includes a casing, a torque support, a ring, an electrical power supply cable and a device for discharging electrostatic charge. The ring is inserted partly around the torque support and forms a bearing guiding the rotation of a winding tube. The discharge device includes an electrical conduction element, which is configured to be in electrical contact with the tube, and an electrical linking element. The ring bears the electrical conduction element. The torque support at least partly accommodates the electrical linking element. The electrical conduction element is configured to be in electrical contact with the electrical linking element. The electrical linking element electrically connects the electrical conduction element to a shielding or to an earth electrical conductor of the cable.

Electromechanical actuator, motorized drive device comprising such an electromechanical actuator and concealment device comprising such a motorized drive device

A method for detecting an obstacle opposing the movement of a screen in a home automation closure or sun protection system includes an electromechanical actuator driving movement of the screen. The electromechanical actuator includes a torque support, a housing, an output shaft, and an electric motor including a stator and a rotor. The system includes a winding shaft rotating the screen and a connecting accessory between the electromechanical actuator's output shaft and the winding shaft. The method includes: determining an angular displacement value of the rotor with respect to the stator; determining angular displacement of the winding shaft relative to the housing or torque support of the electromechanical actuator; determining angular deformation of the kinematic chain between the electric motor and the winding shaft by comparing these two angular displacements; and determining the presence of an obstacle to screen movement from an angular deformation exceeding a predefined value.
