Principle of operation of bearingless modul
Drive control system give ac voltage

on drive winding,
appear torque, rotor rotate

External action force conduce to rotor shift,
position-indicating signal give to suspension control system

Suspension control system rule by electromagnet
Force return rotor in central position
