Vehicle Propulsion

The optimum choice of propulsion specified for any new VECTUS system is determined in accordance with individual customer operating requirements and environment.

Selecting the propulsion system is in collaboration with the customer, accounting for requirements for energy use, environment and local climatic conditions. VECTUS’ control system is not limited to a specific propulsion system. It can supply both linear motor technology as well as conventional drive systems.

 

Linear motors have fewer moving parts ensuring both lower noise levels and reduced maintenance. Linear motors also provide a thrust which is independent of the friction between the wheel and the track. This is particularly advantageous in snow and ice conditions. Alternatively, conventional rotary motors are cheaper and provide better energy efficiency but are less suitable for areas prone to cold conditions.

 

In a warm climate, it is most efficient to have on-board power, particularly if there are high power consumption requirements to drive continuous air conditioning. Power collection (nominally 500VDC) can be provided as an integral part of VECTUS’ track structure and will not significantly impact on the overall dimensions of the track.

 

For a system with a large number of vehicles, the reliability of the vehicle is of utmost importance. A precise and consistent performance of the drive system is a vital component in order to run with short headways and with minimal margins for unwarranted safety brake applications.
