What makes magnetic levitated flywheel energy storage a little special is that nothing actually does touch the rotor. Some of the coils surrounding the rotor act like the coils of a 3 phase electric machines. Those coils convert electric energy to mechanical energy to spin up the rotor in motor mode. The same coils later convert the mechanical ...
