HIGH EFFICIENCY FLYWHEEL SYSTEMS

There are several ways to cool flywheel energy storage

Feasible solutions for rotor heat dissipation in flywheel energy storage systems mainly include: filling low-temperature inert gases to enhance rotor convective heat exchange without significantly increasing low-speed flywheel friction losses; designing low-loss motors, typically using multi-phase winding designs to eliminate high-frequency shockwaves, thereby reducing rotor eddy current losses; and considering the feasibility of cooling structures based on existing research in vacuum oil cooling.
