Flywheel energy storage device

Patent ·
OSTI ID:6422978
An energy-storing flywheel device is described for a motor vehicle comprising: a rotary flywheel on a vertical shaft, the flywheel being releasably couplable to a drive means and being adapted to drive a driven mechanism; the shaft having a shaft axis; a bearing means for journally supporting the shaft, the flywheel including a rotatable magnetic ring structure supporting permanent magnets; and a spacing piece disposed between the rotatable magnetic ring structure and the shaft; and a magnetic supporting means for the rotatable magnetic ring structure. The magnetic supporting means comprises a stationary magnetic ring structure concentric about the shaft axis and below the rotary ring structure. The stationary magnetic ring structure supports permanent magnets.
