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

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 ...

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 ...

The quest for energy efficient electric motors has generated a lot of interesting ideas. One of the latest is said to push the efficiency of induction motors to better than super-premium levels by ...

A motor control IC is a convenient way to implement custom motor drive algorithms such as the single-phase induction motor (SPIM) control. A generalized control algorithm, implemented and tested in an ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.
