abstract = {{In the framework of the High-Luminosity Large Hadron Collider project at CERN, a Full Remote Alignment System (FRAS) is under development, integrating a range of solutions for the remote positioning of accelerator components. An important component of FRAS is the motorized actuator allowing the remote adjustment of accelerator components with a micrometer resolution. These actuators need to fulfill multiple requirements to comply with safety rules, and be highly reliable and maintenance free as thus are located in a harsh environment. The integration of the safety functions required for the FRAS was crucial, with the motorized actuators able to provide an absolute position monitoring of the available stroke, integrating electrical end-stops and having an embedded mechanical stop as a hardware safety layer. In addition, the design has been elaborated to allow a rapid, in-situ readjustment of the nominal stroke in order to cope with potential readjustment requirements, following long-term drifts caused by ground motion. This paper describes the design approach, prototyping and qualification of these motorized actuators.}},
