| Summary: | accounting for the effect caused by extending the rotor past axisymmetric finite element model and illustrate the fringing bearings have replaced ball or thrust bearings. However, current reduction. Several rotor/stator configurations, eddy currents cause a loss of power and instability in effect that occurs with magnetic bearings. A fringe factor field and the input or control current causes the for the power loss, while the phase lag between the magnetic inates. and solid wedge pieces are used to determine the including solid metal, laminated washers, tapewound lam- instability. This study incorporated finite element studies magnetic bearings. The eddy current magnitude is responsible Modern uses of rotating shafts depend upon bearing speeds and of magnetic thrust bearings using static bench testing order to accommodate these excessive parameters, magnetic procedures to investigate configurations that promote eddy smallest phase lag configuration. Finite element analysis temperatures that exceed normal operating parameters. In the stator is developed using finite element analysis. will compare a solid configuration bench test with an |
