Linear Synchronous Motors

Tempesto

The Linear Synchronous Motors (LSM) are positioned in the station, behind the station, and on this section of track in front of the station. The LSMs are even installed in the track as it starts to climb up this tower. The white LSMs use electricity to provide a magnetic force that attracts and repels the permanent magnets installed under each train's car. Computers control the polarity of the electricity as well as the timing of when the LSMs are energized and de-energized in order to smoothly propel the trains forward or backward. The computers can also alter the operating of the LSMs to provide a braking force. This happens at the end of the ride's cycle.
