【摘要】:針對永磁調速器(permanent magnet device,PMD)在三維磁場的仿真計算忽略了導體盤渦流生熱對性能的影響,提出一種基于電磁-熱耦合的有限元分析方法。利用Ansoft Maxwell和Ansys Workbench軟件搭建永磁調速器的電磁場和溫度場耦合仿真模型,分析渦流生熱對導體盤及永磁體性能參數(shù)的影響,將渦流熱功率作為熱源載荷導入溫度場,并在Transient Thermal模塊中進行溫度場仿真,將溫度場仿真結果用于修正永磁調速器的性能參數(shù),最終通過磁場仿真計算輸出轉矩。仿真結果表明:基于電磁-熱耦合計算的轉矩結果較改進前相比與實測值誤差更小,適用于工程計算。
[Abstract]:A finite element analysis method based on electromagnetic-thermal coupling is proposed for permanent magnet governor permanent magnet device (PMD), in which the effect of eddy current heat generation on the performance of the conductor disk is neglected in the simulation of the three-dimensional magnetic field. The coupling simulation model of electromagnetic field and temperature field of permanent magnet governor is built by using Ansoft Maxwell and Ansys Workbench software. The influence of eddy current heat generation on the performance parameters of conductor disk and permanent magnet is analyzed. The eddy current heat power is introduced into the temperature field as a heat source load. The temperature field is simulated in the Transient Thermal module. The temperature field simulation results are used to modify the performance parameters of the permanent magnet governor. Finally, the output torque is calculated by magnetic field simulation. The simulation results show that the torque results based on electromagnetic and thermal coupling are smaller than those measured before, and are suitable for engineering calculation.
