Abstract
A capacitive sensor system for an active magnetic bearing supporting a rotating shaft and flywheel in a flywheel energy storage system integrates sensor elements into the bearing stators, thereby conserving valuable space within a vacuum housing enclosing the flywheel energy storage system. High frequency resonant processing provides intrinsic linearity and noise immunity while permitting fast response times. Simple design of the sensor system permits all sensor electronics to be readily packaged within the vacuum housing.
