Abstract

A pseudo-levitation permanent magnet repulsive bearing and drive system arrangement 1, 2, 3, 15 & 16 for a large diameter composite flywheel 14 for mechanical / electrical energy storage is provided. The system is designed to transmit torque and cope with the expansion of the flywheel 14 when it is running up to its maximum speed. The magnets 13 are arranged in a frustrated cone to centralise the running axis and to subject the upper rotating magnet array to radial centric forces opposing the centrifugal forces acting upon this array to maintain its integrity. This application describes how the levitation system functions utilising multiple concentric rings of a prime number of permanent magnets and special drive spokes, which deflect vertically and radially in concert with the flywheel as it speeds up. To prevent instability the lower fixed magnet arrays are rectangular, with square ends or basically rectangular with semi-circular ends such that the rotating magnets never overhang at either end, the fixed magnet as the flywheel expands due to centrifugal force. The spokes are attached to a hollow central shaft which rotates on ceramic bearings or other bearing types including oil lubricated, air or magnetic bearings, around a fixed central shaft.
