Armed with even with the most-sophisticated motion controller, engineers can still find it difficult to attain precise linear motion unless the mechanical components are appropriately designed for the ...

Beckhoff’s AL8000 linear motors can now deliver greater accuracy and synchronization with the company’s new TwinCAT Cogging Compensation software. According to Beckhoff, this software enables linear ...

Linear bearings, also called linear guide systems, have been used in the U.S. since the early 1900s, most commonly in printing and textile industries. Previously limited to steel ball bearings, now ...

Microelectromechanical systems (MEMS) electrothermal actuators are widely used in applications ranging from micro-optics and ...

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 ...

The integration of rotary and linear motions within a single actuation system has emerged as a transformative development in modern electromechanical engineering. Rotary-linear actuators combine the ...

Perhaps the most persistent nonsense in physics: the perpetual motion machine. Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the ...

Perpetual motion—it's fun to say that. For some people, perpetual motion machines hold the secret to everlasting free energy that will save the world. To them, it's a machine that is just beyond our ...
