AMB offers advantages such as, contact less and friction free operation, excellent performance over a wide range of temperature, no need for lubricant and longer life. Technology of magnetic bearings can be considered as a new field of research in Iran. This paper presents design, manufacturing and control of a magnetically levitation system with successful operation. This research concluded with documentation of the AMB technology which is prerequisite for earning the technology of active magnetic systems (AMS) and paves the way to develop it. M3 ER -
