For space applications requiring compact high-torque actuation we recommend the products of our partner Avior Control Technologies, Inc. Avior manufactures a diverse and flexible product line of housed actuators, which offer proven reliability and performance in the most demanding motion control applications.
Avior actuators achieve their torque density by employing high-speed motors and high-reduction precision (low backlash) planetary gearing. Holding brakes and kinematic feedback transducers (position, velocity, acceleration) are available within the same package. They are supplied with different motor technologies and in various configurations:
- Stepper Motors: Avior Stepper Catalog
- Brushless DC Motors: Avior Brushless Actuator Catalog
- Linear Actuators: Avior Linear Actuator Catalog
- Eddy Current Dampers:
These actuators employ space-rated materials and processes and can be supplied not only for the vacuum space environment but also for cryogenic (down to 4° K) and high-temperature (up to +280°C) operation.
