Abstract: This article proposed a compact and highly efficient flywheel energy storage system (FESS). Single coreless stator and double rotor structures are used to eliminate the idling loss caused by the flux of permanent magnet (PM) machines. A novel compact magnetic bearing is proposed to eliminate the friction loss during high-speed operation.
Moreover, the magnetic levitation system, including an axial thrust-force PMB, an axial AMB, and two radial AMB units, could levitate the FW rotor to avoid friction, so the maintenance loss and the vibration displacement of the FW rotor are both mitigated.
Then, FEM is used to validate the current and position stiffness to ensure good linearities and sufficient load capacities. Experimental results show that the magnetic bearing can provide stable levitation for the 5540-kg flywheel with minimal current consumptions.
VI. CONCLUSION AND FUTURE WORK This paper presents a novel combination 5-DOF magnetic bearing that is highly integrated into a shaft-less energy storage flywheel. The proposed magnetic bearing is a crucial component for the flywheel to achieve double energy density.
