| Abstract: | The electromagnetic field,the temperature field and the coupling between themselves in a thrust magnetic bearing rotor system were investigated in which the heat generated from the eddy cur- rent loss of solid cores and the copper loss of coils were taken into account.The FEM solution of an ax- ially symmetrical temperature field was presented in consideration of the electromagnetic-temperature coupling.The numerical results reveal that the temperature increment is mainly due to the eddy cur- rent loss in the solid thrust disk. |
