Outline of Final Research Achievements

A non-contact magnetic suspension carrier system with a self-propelled mechanism on the rail was aimed 24 hours, 365 days non-contact levitation using the power supplied by the solar generator. Magnetic suspension carrier systems with electromagnets installed on a carrier can reduce initial cost than systems with electromagnets on a track rail. However, the carrier contacts power lines temporarily or continuously because it is necessary to supply power in the conventional carrier systems. A magnetic suspension carrier system combined with a non-contact-power-supplied by a solar power generation was developed to avoid such contact. The carrier system is installed with a secondary battery the power supply in the non-generated period. The carrier system can be achieved 120-hour-non-contact levitation while charging the on-board battery.

Academic Significance and Societal Importance of the Research Achievements

従来の磁気浮上系の短所は，初期コスト，運転コストが高いことが上げられる．この研究成果として，磁気浮上搬送装置において，比較的低コストな搬送車側に電磁石を搭載する方式では，従来では連続的長時間の非接触浮上が難しかったが，この研究により，低コストかつ連続的な非接触浮上が可能となった．また，低消費なセンサなど周辺機器の開発を行ったことにより，消費電力を2.2kgの質量である浮上体を200mW以下と，できる限り少なくすることができ運転コストの低減が行える事を示した．
