- Abstract:
- In this paper,the temperature field of six-ring redundant axial magnetic bearing is simulated andcalculated by ANSYS Workbench and the reasons that result in the temperature rise of six-ring redundant axialmagnetic bearing are discussed. What ’s more,the influence of some parameters such as the magnetic circuitarea,the side wall of magnetic circular,rotating speed on six-ring redundant axial magnetic bearing are ana-lyzed and the structure design and calculation methods of temperature rise are put forward in this paper. Theresults show that,the structure of six-ring redundant axial magnetic bearing has great influence on the temper-ature rise of rotor. When the magnetic circuit is designed,the magnetization of rotor should be avoided. Thereconstruction of failure has small influence on the temperature rise of rotor,which can be ignored. Comparedwith the two-ring redundant axial magnetic bearing,the six-ring redundant axial magnetic bearing has higherreliability,mechanical property and preferable thermal characteristics.
