An electromechanical actuator for a home automation closing or sun protection installation includes an electric motor, a reduction gear and a spring-operated brake (15), which includes a helical spring (22), a drum (23), an input member (24) and an output member (25). The drum (23) includes a housing (26). An inner friction surface (27) of the housing (26) of the drum (23) cooperates with at least one turn of the helical spring (22). The spring-operated brake (15) also includes at least one ring (50) positioned between an outer surface (51) of the input member (24) and/or the output member (25) and the inner friction surface (27) of the housing (26) of the drum (23). The home automation installation includes one such actuator. |
