This paper deals with a bearingless rotary machine that is capable of stable controlling the levitated position of a rotor of an induction motor with a squirrel-cage type rotor under loaded conditions. This bearingless induction machine is capable to serve as an electric motor and also as a magnetic bearing for magnetically levitating and supporting the rotor of the machine. The stator has winding for rotating the rotor and winding for positional control of the rotor in a given radial position. The paper deals with the field oriented control of the bearingless induction machine. Simulations were done with parameters of designed machine based on classical induction motor with mechanical bearings. Designed machine has four-pole drive winding and additional winding to centre the rotor in the machine. Both windings are distributed in the stator slots. Power and voltage rating of the four-pole winding is 3kW/220V and of the two-pole winding for levitation is 250W/30V. Simulation results of the whole system are presented.
