A Novel Magnetic Suspension Flywheel Battery with a Multi-Function Air Gap

In this study, a novel magnetic suspension flywheel battery with multi-function air gap is proposed. Based on the unique gap, degrees of freedom between control circuits can be independent each other, reducing coupling effect freedom. The proposed system topology inherits advantages battery. However, due to breakthrough overall in flywheel, and protection measures, has more precise design circuit, decoupling, high-stability control, energy storage. First, advantages, geometric characteristics, circuit are introduced analyzed. Then, position length conventional optimized ensure best performance entire circuit. motor, settings detail. Finally, tests conducted, good experimental results show that anti-interference ability decoupling ability.
