Abstract

Energy is stored in a hoop 12 spinning around a stator 10 both made of mild steel. At the interface between them there is a cavity in which there are conductors to provide a magnetic bearing between the hoop and the stator. A magnetic levitation device keeps the hoop levitated. Energy is imparted to and withdrawn from the hoop by means of linear reluctance motors. <IMAGE>
