This tutorial aims to give the student an overview of active magnetic bearing (AMB) systems. The course starts with a brief discussion on the history of magnetic bearings. The course then quickly moves to the present application of AMBs for a wide variety of industries. This portion of the course is intended to give the audience an appreciation for a complete magnetic bearing development life cycle, from early concepts, through prototype testing and field commissioning, to manufacturing improvements for high-volume production. The course highlights design decisions that can be made to optimize cost, schedule, efficiency, reliability, thermal performance, and vibratory response, among other considerations. Of note, the course discusses the development life cycle of a turboexpander-compressor and a chiller that are currently in production.
The course concludes with a discussion on future/near-term technological improvements for magnetic bearings. The course discusses innovative system applications, touches on the incorporation of the internet of things (IoT) in magnetic bearing controllers, and discusses high-speed and long-distance data transfer applications. The course concludes by discussing two upcoming real-world magnetic bearing applications: a CO2 blower used for habitable space applications and an implantable total artificial heart used for the treatment of patients with end stage heart failure. Key software features enabling the development of these applications are highlighted.
