Vectus PRT
Vectus approached Force in 2004 regarding a PRT development system. Having worked on several PRT applications before we were able to provide valuable advice and bring extensive Linear Induction Motor and engineering knowledge to the project.
Vectus' concept for their PRT system is that each vehicle can contain up to 4 passengers and their luggage with vehicles being used only on request so energy is consumed on an actual per passenger usage basis.
Thrust is generated as a reaction plate on the bottom of the vehicle passes over the motors embedded in the track with braking achieved by the reversal of the current to the individual motors as required. Performance of a PRT system is usually measured by average vehicle speed and passenger capacity however speeds greater than 40km/h are safely achievable on single cars as well as multiple car blocks.
The 400m test track in Uppsala, Sweden has been operational for over 2000 hours without a LIM failure or problem. More than 100 bespoke LIMs are mounted in the track at intervals of 3.5 metres (11.5 ft) with the reaction plates mounted underneath the passive vehicles. The LIMs are sealed against environmental conditions and operation is not affected by extremes of temperature. In snow and ice conditions, where traditional transport methods suffer due to lack of available grip on roads or rails, the Vectus PRT system performs flawlessly at normal operating speeds as acceleration and braking do not rely on contact friction.
Permanent magnet braking has been developed to offer failsafe and consistent stopping capability. The brakes bring the vehicles to a controlled speed without any physical contact between the vehicle and track - another low maintenance solution that remains fully operational in all weather conditions.
