摘要
高速电机中定子铁芯损耗占总损耗比例相对较大,高频运行时定子软磁材料的准确选取限制了整机效率的提升,为此引入材料性能因子作为选材准则.以无取向硅钢材料B20AT1500、极薄硅钢材料 10JNEX900 和新型非晶合金带材AYFA-Z的性能因子作为判据,得到 3 种材料的最佳使用频率范围.采用数值计算方法,对比 3 种材料的电机在空载和负载下的性能.结果表明:根据软磁材料性能因子,可以准确、快速判定出工作频率范围内的最优软磁材料.最后,通过搭建高速电机实验平台,完成 120 000 r/min的超高速电动机的参数测试和性能测试,进一步验证了根据材料性能因子作为铁芯材料优选判据的可行性.
Abstract
The stator core loss accounts for a relatively large proportion of the total loss in high speed motor,and the accurate se-lection of stator soft magnetic materials during high-frequency operation limits the improvement of overall efficiency.Therefore,material performance factors were introduced as the selection criteria.The performance factors of non-oriented silicon steel material B20AT1500,ultra-thin silicon steel material 10JNEX900,and new amorphous alloy strip AYFA-Z were used as criteria to obtain the optimal fre-quency range of the three materials.The performance of motors made of three materials under no-load and load conditions was compared by numerical calculation method.The results show that the optimal soft magnetic material within the operating frequency range can be accurately and quickly determined based on the performance factor of the soft magnetic material.Finally,a high-speed motor experimen-tal platform was established,and parameter testing and performance testing of a 120 000 r/min ultra high-speed motor were completed,further verifying the feasibility of using material performance factors as the criterion for selecting iron core materials.
