Thermal Model For A High Temperature Active Magnetic Bearing

In order to design an AMB working at high temperature the thermal aspect has to be explored. The limitation of current must be determined as well as the temperature of work of the material. A steady state model including the thermal radiation has been built on the base of a thermal network. Temperature dependent thermal parameters of the component of the AMB were measured with experiments throughout a model fitting. This model programmed in MATLAB is fast enough to work in AMB optimization design routines. An application of choice of coil high temperature wires in function of their life span is presented.
