A linear induction motor for braking

A linear induction motor for braking

University of Newcastle


The 'Zero Wheel Slip Linear Induction Motor' aims to reduce dependence on friction between wheel and rail for traction and braking forces, but with minimal changes to the existing rolling stock and infrastructure. The concept is based on the well known linear induction motor technology (LIM), which has been successfully employed in the railways through the idea of Eddy Current Brakes. A more reliable stopping performance removes both the requirement for defensive driving and any issues of low rail adhesion conditions. This can greatly increase potential capacity on the network.

This braking solution uses known technology in a novel way, maximising the reuse of existing railway infrastructure by including the running rails as part of the design.
