Axial force evaluation in permanent magnet thrust bearings subject to demagnetization and temperature effects

摘要：

　　This article presents a 2D axisymmetric finite element model allowing to evaluate the axial force developed by a permanent magnet thrust bearings,including demagnetization and temperature effects.For this purpose,a linearized B-H curve is included in the model,with coefficients depending on the temperature.The axial force evaluation,as a function of the operating temperature is validated experimentally on a test bench.Finally,based on this model,the performance of thrust bearings using either SmCo or NdFeB are compared.
