Linear induction motor

(Redirected from LIM)

A linear induction motor (LIM) is a form of electro-magnetic propulsion containing no moving parts. They may replace a traditional lift hill and brakes. Typically LIM systems launch the roller coaster train from the station extremely quickly. They have since been superseded by linear synchronous motor technology.

The first use of linear induction motors for launching a train was in 1996. Unlike prior launched roller coasters, which used a weight drop launch, flywheel launch or electric winch launch, LIM technology requires no mechanical contact between the track and the train, reducing wear and tear.[1]
