The controllable suspension force of the permanent magnet type bearingless motor is the result of the torque winding air gap magnetic field and the floating winding air gap magnetic field which are generated together with the rotor permanent magnet and the torque winding current. The rotor field oriented operation controls the motor idle running torque. The winding air gap magnetic field is generated by the rotor permanent magnet alone, that is, the torque winding rotor magnetic field and the torque winding air gap magnetic field are the same magnetic field. At this moment, the torque winding air gap magnetic field amplitude is stable and the real axis and air gap magnetic field direction of the common coordinate system In common, if the amplitude of the air gap magnetic field is stabilized and the real axis of the common coordinate system is fixed in the direction of the air gap magnetic field when the motor load is running, the controllable suspension force model in this coordinate system will have the same manner as the equation. 4. It is the basic idea of ​​the decoupling control of permanent magnet type bearingless motor based on the directional control of the torque winding air gap.
Traditional permanent magnet type bearingless motor rotor field oriented decoupling control strategy suspension force algorithm The high nonlinearity between clutter, suspension force and suspension control current is limited in high speed application. This paper is based on permanent magnet type bearingless motor suspension. Force generation mechanism, aligning a kind of externally mounted permanent magnet type bearingless motor with torque winding air field directional control. Based on the mathematical model of permanent magnet type bearingless motor dq, the torque winding air gap magnetic field orientation coordinate system is derived. The motor suspension force, air gap flux linkage and torque mathematical model are used to construct the air gap magnetic field orientation control system of permanent magnet type bearingless motor, which can deal with the shortcomings of rotor field oriented control, and then correct its The feasibility of the simulation is verified. The simulation results show that the motor not only completes the decoupling control between torque and suspension force, but also has outstanding dynamic and static functions.
