Roller Coaster Question!

Sunday, May 22, 2005 12:23 PM
Hi! Does anyone know the name of the certian type of roller coasters that uses magnets to launch roller coasters instead of lifthills. I think rock n' roller coaster at disney's mgm and batman and robin at SFGA are two examples.

LIM (Linear Induction Motor) Launch Coaster? Magnetic Catapult Coaster? Impulse Coaster? There are a bunch of terms for it, and different types...

Chiller and Rockin Rollercoaster are Lims and use the Lium Launch system.

LIM (Linear Induction Motor) is a form of electro-magnetic propulsion. They replace a traditional lift hill and do not contain any moving parts. Typically LIM systems launch the roller coaster from the station extremely quickly.

Actually, Rock 'n' Roller Coaster uses LSM Propulsion--Linear Synchronous Motor, which is comprised of a slightly different techology than LIMs.

Actually, LSM is *completely* different than LIM since LIMs don't use magnets. LIMs use inductors. Although, to the unlearned eye they would *look* quite similar.

You guys are correct. Sorry for the misleading info.
