Abstract：In this paper,a magnetic field of rotation driving system using permanent magnet suspension is analyzed.The system controls suspended object to move up and down by a voice coil motor driving a cylindrical permanent magnet,realizes the rotation of suspension by four DC servo motor controlling the rotation of four disc permanent magnets.In order to analyze the magnetic field of permanent magnet suspension rotation driving system in the horizontal plane,and relationship of the magnetic field between the four permanent magnets and the iron ball.The iron ball rotation angle change is obtained through the four permanent magnet rotation in the same direction and speed.The simulation results show that the rotation angle of permanent magnet has a certain relationship with the rotation angle of iron ball,and the results can provide a basis for the follow-up study of the system.
