An iterative parameter design method based on leakage coefficient and magnetoresistance coefficient were presented.For each component of the hybrid magnetic bearing

structural parameters were ultimately obtained based on its leakage and magnetoresistance coefficients calculated using an iterative loop algorithm.The calculations were constrained to the degree of magnetic flux density unsaturation for the design goal of achieving a minimum volume while maintaining the maximum required levitation force.Finite element analysis (FEA) software was used to execute simulation analysis and modeling of the three-dimensional magnetic

demonstrating the rationality and validity of the parameterization method and its result.The displacements of rotor and control current curves of the magnetic bearing under floating

static suspension

static shock and at 30 000 r/min were presented.The experimental results testify that the hybrid magnetic bearing designed by the method has a good levitation performance.
