Abstract

PURPOSE: To reduce a starting torque as well as prevent damages of a shaft and a shaft surface by a method wherein a distance between a shaft and a shaft surface is detected by a position detecting element, and the change is compensated by an electromagnet and a current control.
CONSTITUTION: In supporting a load in the thrust direction, when the number n of rotations of a shaft is lowered to decrease the load capacity, a distance C1 between a thrust receiver plate 4 and a thrust gas bearing 5 will be forced to be shortened so that a thrust force F and the load capcity can be balanced. The change of the distance C1 is detected by a position detecting element 1 and transmitted to a current control device 6. The current control device 6 flows current equivalent to the change of the distance C1 to a coil winding 2 of an electromagnet M to increase a magnetic support and compensate the d4crease of the load capacity. In this system, since the solid contact is not given when the shaft starts or stops, damages are not caused and the starting torque is lowered.
