Flywheel energy storage system with a permanent magnet bearing and a pair of hybrid ceramic ball bearings

다국어 초록 (Multilingual Abstract)

A flywheel energy storage system (FESS) with a permanent magnet bearing (PMB) and a pair of hybrid ceramic ball bearings is developed.

A flexibility design is established for the flywheel rotor system. The PMB is located at the top of the flywheel to apply axialattraction force on the flywheel rotor, reduce the load on the bottom rolling bearing, and decrease the friction power loss. The magneticforce of the PMB is analyzed through finite element method, and the force with the air gap of the PMB is verified experimentally. Asqueeze film damper (SFD) is introduced to support the bottom rolling bearing, suppress lateral vibration, and enhance the stability of theflywheel rotor system. A dynamic model of FESS is established through transfer matrix method, Jones-Harris rolling bearing theory, anda finite length bearing dynamic model for SFD, which is verified by measuring the amplitude-frequency response. The effect of SFDradial clearance and unbalanced mass distribution on the dynamics of FESS is discussed. A spin-down test for the FESS prototype isconducted in a moderate vacuum. Results show that the hybrid bearing and flexibility design for the rotor system allow for the use of asmall rolling bearing to reduce the power loss of FESS caused by friction. The developed FESS is simple in structure, stable withoutactive control, low in cost, and convenient in maintenance.
