Linear motor, also known as linear induction motor, is a type of electric motor that generates force and motion in a straight line. There are several synonyms for the word "linear motor" such as linear induction drive, linear synchronous motor, and linear electric motor. A linear induction drive works by producing EMF (Electromotive Force) across a conductor-providing propulsion. A linear synchronous motor is a high-performance propulsion system that uses a combination of simple, compact mechanisms to generate thrust. On the other hand, linear electric motors use alternating current systems to create a magnetic field and propel movement. These synonyms all refer to motors that produce linear motion and are used in a variety of applications, including high-speed trains, elevators, and industrial automation.
