The air-gap eccentricity of motor rotor is a common fault of flywheel energy storage devices. Consequently, this paper takes a high-power energy storage flywheel rotor system as the research object, aiming to thoroughly study the flywheel rotor''s dynamic response characteristics when the induction motor rotor has initial static eccentricity.
Low-speed flywheels, with typical operating speeds up to 6000 rev/min, are constructed with steel rotors and conventional bearings. For example, a typical flywheel system with steel rotor developed in the 1980s for wind–diesel applications had energy storage capacity around 2 kW h @ 5000 rev/min, and rated power 45 kW.
