摘要

本研究針對現階段高速飛輪系統發展限制，提出鐘擺型飛輪磁浮控制系統，其核心技術包括：鐘擺型軸向磁浮軸承結構、切換式徑向磁控設計、自感測技術及功率放大器技術。本研究之軸向磁浮軸承為永久／電磁鐵混合式設計，永久磁鐵之磁力用以克服飛輪轉子本身之重量，當飛輪轉子軸向位置產生偏移時，由電磁鐵產生磁力以節制飛輪轉子位置偏移。而於徑向磁浮系統部分，本研究設計一切換式磁浮軸承系統，其優點為無需偏壓電流。換言之，本研究所設計之磁浮軸承系統，無論是軸向或徑向磁浮軸承，皆可大大降低電能損耗，並提高整體系統可靠度。另外，自感測技術之應用則可免去使用商業感測器，故可降低系統製作成本。藉本研究之設計將可實現低成本、低耗能與高效率之全磁浮高速飛輪電池系統。

The energy-saving Active Magnetic Bearings (AMBs) for high-speed flywheel cell are proposed in this work. The AMB sets mainly consist of PM/Electric hybrid axial AMB, switching-type radial AMB, self-sensing technology for rotor position deviation and power amplifier. The magnetic force induced by PM of axial AMB is employed to counterbalance the weight of flywheel rotor. The magnetic force induced by Electromagnetic bearing is used to regulate the axial position deviation of rotor. In other words, the axial AMB is hardly devoted to providing electric energy as long as the rotor stays at equilibrium. Two of the major merits of switching-type AMB are: no need of any bias current and the number of power amplifiers 50% reduced. On the other hand, the self-sensing technology is employed to replace the commercial gap sensors such that the cost of the AMB system is much lowered down, compared with the traditional design. Briefly speaking, the low cost, energy saving and high efficient AMBs for high-speed flywheel cell can be expected.
