Abstract

A rotating apparatus includes a housing, a shaft at least partially disposed within a first pressure environment defined by the housing, a first magnetic bearing supporting the shaft and being at least partially disposed within the first pressure environment, a sensor operable to sense a position of the shaft relative to the first magnetic bearing, a controller disposed in a second pressure environment independent of the first pressure environment and operable to communicate with the sensor and to generate a control signal for the first magnetic bearing based on the sensed position, and a communication device operable to communicate the control signal between the controller and the first magnetic bearing and to communicate the sensed position between the sensor and the controller without penetrating a pressure boundary defined between the first and second pressure environments.
