Abstract :
This paper introduces a novel design for the flywheel energy storage system which axial stability is actively controlled by an electromagnet while the motions in other directions are restricted by two pairs of permanent magnets in attractive mode. Additionally, we adopt an axial-flux motor/generator which rotor is integrated with the flywheel. The principle of our design is presented in detail and a prototype is fabricated, the modeling and the simulation of the magnetic bearing system are conducted in this paper
