Hanging Type Mag-lev System with Permanent Magnet Motion Control

A type of mag-lev system with permanent magnet motion control is proposed, analyzed, and examined experimentally. This mag-lev system has the structure that the levitating object hangs on the upper iron rail and such parts as magnets, sensors, and actuators are installed on the object. This levitation method is very useful for noncontact conveyance systems, because the conveyance path is very easy to make. This paper describes the success of the construction of the hanging type magnetic levitation system using magnet motion control mechanism.
