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. The Avior line provides two-phase and three-phase permanent magnet steppers. Optional redundant windings, high torque capacity gearing, complementary kinematic sensors and linear translation modules are available to complete a stepper motor actuator tailored to your needs. Standard stepper motor frame sizes range from 0.50” (13mm) to 1.5” (38 mm), with other frame sizes available upon request.  Steppers are not recommended for high mechanical power output applications, and the design engineer must be mindful of load inertia mismatch.
