To fully appreciate the chief advantages of linear motors, it is helpful to compare them to ballscrews, another high-precision rotary-to-linear transmission system. Although typical ballscrews are ...

Linear motors are very quick and precise for positioning, but are also capable of slow, constant-traverse speed for machine heads and slides, as well as tool and part-handling systems. A variety of ...

There are a number of linear motion technologies availableto machine and device designers, each with advantages and disadvantages.Medical device design in particular, in which applications typically ...

Essentially, a guide wheel is a ball bearing that has a special shaped outer race. The inner and outer races of ball bearings are a framework with a groove for the balls to rest in. Burke explained ...

In the next few weeks, linear motors will face their ultimate litmus test. After years in the eye of a swirling technical storm, surrounded by doubters who say they're too expensive, supported by a ...

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.
