Limited Angle Torque Motors

With high torque-to-mass ratio and simple control methods, Limited Angle Torque Motors (LAT’s) or Rotary Switches are ideal for high-response precision control systems with limited angular range.

Cogless Direct Drive Motors

Space Rated Cog-less and Conventional Direct Drive Motors are ideal for precision applications where large through bore must be maximized, torque ripple disturbances must be minimized or the drive configuration does not allow for a geared actuator.

Brushless DC Motors

Housed Brushless DC Motors are much more efficient and capable of driving high load inertias, compared to Stepper Motor Actuators.

Stepper Motors

With high torque-to-mass ratio and simple control methods, stepper motors are the motor of choice for many incremental control applications in the space industry.

Eddy Current Dampers

The Avior advanced Eddy Current Damper (ECD) provides higher damping per unit volume, with lower mechanical and total static friction than competing technologies.

Friction Brakes

The Avior line includes a set of friction brake modules used to hold the output rotation of a DC motor.


The Avior line includes a set of complementary function devices for use in step verification or servo control systems.


Avior high-efficiency planetary gearing modules feature high grade materials, precision machining tolerances and fully preloaded ball bearing arrangements.

Linear Actuators

The Avior line of complementary components includes Linear Torque Modules (LTM’s) that convert the rotary motion of an Avior motor into reliable and accurate linear translation.
