Abstract: Introduced the principle of radial forces generation for bearingless synchronous reluctance motors,and given mathematics models of radial forces,moreover,analyzed and calculated the complicated magnetic field characteristic inside the motors and nonlinear relations between radial forces and windings currents with finite element method,also found the effects of magnetic saturation on radial forces.Analysis results can offer a thoughtway for optimal design and effective control of the motor.
