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 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 ...

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 ...

Here’s how power losses and inertia matching affect the efficiency of linear drives. The operating efficiency of linear drives is of growing concern to machine designers. Here's a look at three common ...

The EMALS is an electromagnetic catapult that relies upon a linear induction motor, rather than a traditional steam piston, to launch aircraft. The linear induction motor, as the name implies, uses ...
