Abstract :
In this paper, the structure and principle of bearing less motor with a rectifier circuit was described. Based on the levitated operation of bearing less motor, an analytical model was developed. The levitation control system of bearing less motor was designed by using the active disturbance rejection control (ADRC) theory. According to the parameters of the experimental prototype, the simulation model was set up with Matlab/Simulink simulation platform. The step response of the system, the start up displacement curve of the rotor and the performance of anti-disturbance of the system were simulated and analyzed.
