The combination of a high-torque step motor and precision spindle not only provides L2018 series linear actuators with a resolution of 5 µm, it also enables 40 N of thrust in compact form.

The rotor turns (as in a conventional stepper motor) but produces linear motion through the nut and threaded screw. This tighter integration increases mechanical advantage as well as resolution.

This paper discusses the technology behind stepper motor linear actuators, what makes them different, and concludes with a detailed example illustrating how they should be sized to move a given load.

In a way, it’s what one would get by unrolling a typical rotary stepper motor. The result is a gearless (and very quiet) linear actuator that controls like a stepper motor.

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

Stepper Motor Linear Actuators August 11, 2010 By DE staff Motion Control Haydon Kerk's high output, CAN stack linear actuators include optimized stator tooth geometry, high energy neodymium magnets.

Four models available The company has introduced new linear stepper motor stages that travel at speeds up to 80 inches/sec with stroke lengths to 144 inches, and acceleration to 1G. Four models offer ...
