What is Flywheel Energy Storage? | Linquip
A flywheel is supported by a rolling-element bearing and is coupled to a motor-generator in a typical arrangement. To reduce friction and energy waste, the flywheel and sometimes the motor–generator are encased in a vacuum chamber. A massive steel flywheel rotates on mechanical bearings in first-generation flywheel energy storage …
