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 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 ...

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 ...

Linear motors are very quick and precise for positioning, but are also capable of slow, constant-traverse speed for machine heads and slides, as well as tool and part-handling systems. A variety of ...

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 ...

The USS Gerald R. Ford, the Navy's newest aircraft carrier, was the first to successfully test launch an aircraft using an electromagnetic launch system (EMALS). The mission and function of EMALS will ...
