Magnetic Bearing Actuator Design for a Gas Expander/Generator
A magnetic bearing system for a high-speed cryogenic gas expander generator is presented. The expander represents a new class of such devices that, in contrast to the earlier technologies, makes use of the expanding gas energy by converting it into electrical power.
