Actuators for space application shall satisfy requirement covering a wide variety of applications. Most spacecraft have appendages, like solar arrays or antennas or payloads, to be deployed and in some cases these appendages need to be continuously rotated or repointed during the mission. Furthermore, a vast majority of spacecraft embark instruments as payloads, where actuation is needed either for pointing purposes, like scanning mechanisms, or refocusing of mirrors, or optical path adjustment (optical wheels, shutters, choppers, etc …) or many others mechanical activities up to soil drilling in case of exploration missions.
