A hybrid foil-magnetic bearing wherein the foil and magnetic bearing parts share
the load at predetermined speeds or operating conditions. Force, flux, strain,
temperature, or acceleration sensors provide a measure proportional to actual load
on at least one of the bearing parts, and this measure is inputted to a load sharing
controller for dividing the load between the bearing parts. In order to provide
control of a hybrid journal bearing which is substantially free of the effects
of a bending mode node resulting from magnetic planes on opposite sides of the
bearing and of sensor non-collocation, a pair of redundant sensors are provided
on opposite sides respectively of the housing for regulating flux on the opposite
sides respectively.
