10 Flywheels Principle of Operation 10

11 GKN Hybrid Power Flywheel Principle of Operation The Mechanical Battery The flywheel is an electric motor Stores energy mechanically Unique MLC Rotor 12kg Spins at up to 36,000 rpm Peak Power 120kW Filament Wound Carbon Fibre Outer Rotor 80,000,000 Strands of aero grade carbon fibre Surface Speed: Mach 1.8 Surface force :250,000g Benefits Very high power density Wide operating temperature range Very high cycle life with no loss of performance Cost effective in volume MLC The inner ring of the flywheel is made of glass fibre mixed with magnetic particles. This provides the magnetic flux for the motor Magnetic Layered Composite 11
