Linear actuator uses a lead screw driven by a permanent magnet dc motor to create linear motion from a dc voltage. When power is removed linear actuator will hold its position. However, if a force ...

Linear actuators are useful things, moving things in straight lines rather than annoying circles like so many motors. [Retsetman] recently built a linear servo actuator of his own design with accurate ...

There are many ways to make a linear actuator, a device for moving something is a straight line. Most of the easier to make ones use a conventional motor and a mechanical linkage such as a rack and ...

Actuators are used in a variety of medical applications ranging from prosthetics through to testing and rehabilitations devices. Actuonix’s medical clients range from startups through multinational ...

In this chapter, I will present a few useful “cookbook” applications for real-time control circuits designed to perform some specific low-level task and interface with a master controller for ...

Big, innovative breakthroughs often result in game-changing technologies. Smaller incremental improvements in essential material components can similarly lead to significant performance and efficiency ...

A look at how modern electric actuators combine mechanical innovation with digital control, enabling rapid product ...

For a PDF verion of this article, click here. Though the understanding of piezoelectrics is more than a century old, there is, of late, a rapidly expanding interest in piezoelectric actuators, because ...

The IP (Ingress Protection or International Protection) code rating is an internationally recognized system developed to standardize the degree of protection that “enclosures” provide against foreign ...
