PMSM Reactance Parameter Test Based on LabVIEW

永磁同步电机的电抗参数是电机设计和实际运动控制的关键参数。针对PMSM电抗测试,分析了直接负载法测试永磁同步电机电抗参数的基本原理,提出一种基于LabVIEW虚拟仪器测试功率角的方法,改进了直接负载法测试电抗参数的方案;设计测试装置对样机进行功率角测试,自动计算和处理获得样机的交直轴电抗,将测试结果与设计值进行对比,验证了测试方法的可行性。

The reactance parameter of permanent magnet synchronous motor is the key parameter of motor design and actual motion control.Aiming at the PMSM reactance test,the basic principle of testing the reactance parameters of PMSM by direct load method is analyzed,a method of testing the power Angle based on LabVIEW virtual instrument is proposed,and the scheme of testing the reactance parameters by direct load method is improved.The test device is designed to test the power Angle of the prototype,auto⁃matically calculate and process the cross-axis reactance of the prototype,and compare the test result with the design value,which verifies the feasibility of the test method.
