| Abstract: | The principle of radial force in bearingless switched reluctance motor is introduced briefly, and the electromagnetic field of bearingless switched reluctance motor with the magnetic saturation is analyzed and calculated by using the finite element method,in which the torque and radial force charac- teristics are analyzed.The influence of main winding and auxiliary winding currents on the magnetic field of motor and the nonlinear relation from the winding currents to the torque and radial force are studied.The effective area of winding currents that can ensure steady operation is obtained,which pro- vides the basis for the effective control of motor. |
