Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

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 ...
