摘要
随着大功率电磁轴承在工程中的广泛应用,其产生的能量损耗越来越大,加之电磁轴承内部结构紧凑,散热较为困难,对电磁轴承的冷却提出了更高要求,有必要对电磁轴承开展冷却优化研究。本文以冷却散热为目的,采用不同冷却方案对某工程项目所用电磁轴承进行了冷却优化,基于仿真计算的方式,对电磁轴承的温度场进行了仿真分析,并根据仿真与试验结果提出优化方案:采用单端内圈冷却方案对定转子温升具有较好的抑制效果。
With the wide application of high-power Active Magnetic Bearing(AMB)in engineering,the energy loss is increasing.In addition,the compact internal structure of AMB makes it difficult to dissipate heat,higher requirements are put forward for cooling of AMB.Therefore,it is necessary to do research on cooling optimization about AMB.For the propose of cooling heat dissipation,different cooling schemes are used to cooling optimization of AMB for an engineering project,and the temperature field of AMB is simulated and analyzed by means of simulation calculation.According to simulation and test results,an optimization scheme is proposed:the single-end inner ring cooling scheme has better suppression effect on temperature rise of stator and rotor.
