Flywheel Technology Helps Reduce Costs
Flywheel technology offer promise as an ecologically- and economically-efficient component for light rail vehicles. This article provides an overview of how modern flywheels work and why they can save energy. Modern flywheels bear a high capacity of on-board energy storage in a small space. Their rotors are made of high-tech carbon fiber and run under vacuum in a horizontal plane at more than 20,000 rpm. For vehicle applications, they are suspended by a cardan suspension. Combined with a motor-generator and modern control and power electronics, they can store and deploy energy at any moment. Managing these energy flows allows for a reduction of up to 25% in traction energy and can potentially reduce related infrastructure costs. This technology also needs no chemicals and can be easily recycled. After successful prototype tests, a series version of this equipment is now being developed.
