| Abstract: | In this paper the levitation principle of bearingless induction motor is described.The basic idea of independent control of levitation winding is analyzed.The bearingless induction motor can be equal to two equivalent motors-torque producing motor and suspension motor.According to the voltage-model method the flux linkage observer which identifies the air gap flux linkage of torque winding is developed.The current of levitation winding can be calculated by means of the displacement controller and the flux observer.The simulation model of the independent control of levitation winding with matlab/simulink is proposed and the result is reasonable. |
