Abstract： A field balancing method was proposed to solve rotor unbalance vibration problems in the Magnetically Suspended Flywheel (MSFW). Based on the equivalence principle between magnetic control force and unbalance centrifugal force, the rotor unbalance can be calculated and corrected by measuring the magnetic force. A zero-displacement controller was designed to make the rotor rotate around its geometric axis. Then the magnetic force was obtained by measuring the control current since the magnetic force was a linear function of the control current. This method eliminates the errors introduced by the oversimplification of dynamic model in conventional methods and is applicable especially for the high-gyroscopic-effect-pancake magnetically suspended rigid rotor. The experiment results demonstrate the method is effective to improve the balancing accuracy for the magnetically suspended rigid rotor system.
