In order to double today's jet engines' propulsion capability, lightweight, high-efficiency, high-speed and high-temperature components are sought. These requirements put the conventional components such as the mechanical bearings under excessive constraints and make them obsolete. In this context, SatCon Technology Corporation has developed a high-speed, high-temperature (50 krpm, 600 deg C) magnetic bearing system that has the potential of meeting the requirements described above. This magnetic bearing system, comprised of two radial and one double acting thrust bearings, was successfully tested to 50,000 rpm. This paper describes the development of this system from its design, through its fabrication and final testing. Details on the system and component requirements are presented, along with a step-by-step design and trade-off analysis. Test data and their discussion are provided as well.
