| Abstract: | The structures of radial active magnetic bearings (RAMB) were listed, the main parameters related to the performance of a RAMB were analyzed and the basic equations for geometric parameters of stator, rotor and winding were given. The analytical design of a RAMB example was performed with assumptions of that all electromagnets were decoupled and their nonlinear iron properties were negligible. Magnetic field analysis of this example by the 2D finite element method revealed the influences of poles arrangements, magnetic resistance, magnetic leakage and fringe effect which were all neglected in the previous design. The hypotheses for structural design were testified their validity by the design results of the RAMB and the magnetic field analysis. |
