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

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 motors are proliferating. They give machines the absolute highest precision and dynamic performance. Linear motors are very quick and precise for positioning, but are also capable of slow, ...

Once considered expensive and exotic, linear motors are at last becoming valuable workhorses in a variety of OEM applications. Besides delivering nanometer precision in the semiconductor and machine ...

Launching things with electromagnetism is pretty fun, with linear induction motors being a popular design that finds use from everywhere in hobby designs like [Tom Stanton]’s to the electromagnetic ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

READERS of a certain age may remember “Fireball XL5”, a children’s television programme devised by Gerry Anderson about a spacecraft of that name. Instead of taking off vertically, as real spacecraft ...
