Pod launch

6 posts in this topic

I was wondering does TOT use LSM or LIM? What are the differences.And is the pod brought forward by magnets or pushed away by them?I assume LIM is when the pod is pulled forwar as induction means to bring forward.

Taken from http://americacoasters.com/CoasterInfo/typ...soflaunches.php Linear Induction Motor (LIM) Launch - Launch mechanism introduced by Disney. Premier Rides was the first to introduce the LIM launched roller coaster. LIMs are electric motors which create linear (straight line) motion. Conductive aluminum fins are located on each side of the train and stator (electrical) coils are located in a series of anchored motor housings which extend out from beneath the loading platform along the track to more than 200-feet, ending at the base of the first hill/element. An electrical current pulses through the stator coils, which in turn creates an electro-magnetic force that pulls at flat metal bars, accelerating the train out of the station. As the train accelerates, each fin passes between a pair of stator coils which are powered consecutively in a time sequence, pulling the train forward till it reaches its maximum speed. Example: Flight of Fear, Paramount's Kings Island Linear Synchronous Motors (LSM) Launch - Launch mechanism first used by Intamin AG. A series of extremely powerful rare earth magnets are mounted on the car. Linear motors, which are placed on the track, are activated by electricity. The motors then create magnetic fields which pull the car forward by attraction. Magnetic fields also repel the magnets which are mounted on the vehicle, increasing speed. Example: Superman: The Escape, Six Flags Magic Mountain
