ABSTRACT:
A method and system for balancing a rotary member. The system preferably comprises balancer stand, a stator element including and a levitation element. The rotary member is coupled with the levitation element. The rotary member and the levitation element are positioned above the stator element which preferably comprises a superconductor element. The rotary member and levitation element are suspended above the stator element when the superconductor element is activated through field cooling. The rotary member is titled with respect to a direction of gravity such that an imbalanced portion of the rotary member rests at the lowest point of the rotary member. The imbalanced portion is thereby identified and can be corrected.
