| Abstract: | Double winding bearingless switched reluctance machine is a multi-variable,strong coupling,nonlinear system. The establishment of accurate suspension force mathematical model is the key to realize the stable suspension control. Based on the structure and suspension mechanism analysis of the double winding bearingless switched reluctance machine,the radial suspension force mathematical model was deduced. Using Maxwell 13. 0,the analysis model was established. The relationship between levitation force and winding currents and angles were calculated using the static analysis method. Based on the transient analysis method,power winding voltage waveform is calculated. |
