The first linear motor was conceived by Wheatstone more than 100 years ago. But large air gaps and low efficiencies prevented linear motors from being widely used. Though they still have relatively ...

Linear induction motors (LIMs) are specialised electromagnetic machines that convert electrical energy directly into linear force, thereby eliminating the intermediary rotary step inherent in ...

[Raul] built a cheap linear actuator out of a drawer slide and a surplus flatbed scanner. A few builds we’ve seen, like the PCB drill press or the horribly inefficient thermostat, used linear ...

Download the PDF of this article. In high-throughput applications, standard triangular or trapezoidal motion profiles have been widely utilized to reach a desired position quickly. As shown in the ...

NUM has launched a series of brushless linear servo motors designed for continuous duty cycle machine tool applications. The new LMX series linear motors have their moving coil primary section ...

When most engineers hear the term motor they most-naturally think of rotating arrangements such as brushed DC, brushless DC, stepper, or variable-frequency prime movers. But a motor doesn’t have to be ...

Since the beginning of the coronavirus crisis at the latest, the pharmaceutical industry and laboratories have been under pressure to realize the highest possible levels of automation. Necessary here ...

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 ...
