浅析稀土永磁无铁心电动机系统用能情况的测试方法

摘要

介绍了利用高精度功率分析仪、工频和霍尔电流传感器及转矩转速传感器所组成的测试系统,在稀土永磁无铁心电动机系统测试中的应用.解决了以往类似测试系统所产生的数据不确定性问题,提高了测试精度,缩小了误差.这为今后测试类似电机系统提供了一种新的测试方案.%The application of the test system which was composed of the high precision power analyzer,the power frequency and the Holzer current transformer and the torque speed sensor in the test of the rare earth permanent magnet coreless motor system was introduced.The problem of data uncertainty caused by similar test system was solved,and the test precision was reduced.It provided a new test scheme for testing similar motor systems in the future.
