The flywheel (also named as rotor or rim) is the essential part of a FESS. This part stores most of the kinetic energy during the operation. As such, the rotor’s design is critical for energy capacity and is usually the starting point of the entire FESS design. The flywheel (also named as rotor or rim) is the essential part of a FESS.
