Mankind’s activities in space are constantly increasing. Modern satellites and other spacecraft are equipped with a large number of rotary actuators. Conventional friction-based brakes or brakes with mechanical locking cannot be used to block rotational movements, e.g. when fixing antennas or solar panels in their orientation, due to the risk of cold welding or abrasion. <\/p>\n\n\n\n

The conventional approach uses stepper motors that have an inherent cogging torque due to magnetic reluctance. However, the size of the stepper motor is sometimes determined not by the required rated torque, but by the required braking torque. This makes these actuators unnecessarily large and heavy. <\/p>\n<\/div>\n<\/div>\n\n\n\n
