Design Considerations for an Active Magnetic Bearing System Used in Aerospace Environmental Control Systems

The purpose of this paper is to share with magnetic bearing enthusiasts the design considerations that have lead to the successful application of an active magnetic bearing system used in aircraft environmental control system. The use of a magnetic bearing system in an aerospace application must meet the rigid standards for in-flight systems. This includes both mechanical and electrical operational and safety requirements. An introduction to the application of the magnetic bearing will be explained. A detailed discussion of the C-130E magnetic bearing system will explain the physical design of the bearing assembly and the design of the control system. Further discussion will explain the significance of the manufacturing process and minimizing the costs of maintainability of the magnetic bearing system in the field. Milestones of the magnetic bearing development and operational data will be provided.
