| Outline of Final Research Achievements |
We developed a new ac Ampere type maglev system for an aluminum tube, and investigated the effects of levitation force enhancement, power saving, and reduction of heat generation. As a result, the new maglev for an aluminum tube exhibited all the above effects that ac Ampere type maglev for an aluminum plate acquires. In addition, to realize electromagnetic suspension of an aluminum ring, we developed a prototype of ac Ampere type maglev for an aluminum ring. The prototype includes an electromagnet arranged from the upper side of the ring and six electromagnets around the ring. It was proven that the prototype generates quasi-static ampere force larger than the sum of induction force and own weight of the ring and therefore can continue pulling up the ring. From these verification tests, we conclude that ac Ampere type maglev technique we have proposed can be applied to various shapes of aluminum products such as plate, tube, ring, and frame without impairing its effectiveness.
