详细介绍了基于LabVIEW的共直流母线型电机测试系统架构组成,采用高精度高动态响应的ASD伺服驱动器,选配合适的电流传感器与功率分析仪,上位机LabVIEW与MATLAB结合绘制电机MAP图、外特性曲线,上位机LabVIEW与SQL数据库建立联系,共直流母线型系统优化了能量循环方式,实现能量母线侧内循环。测试结果表明:该系统功能全面,可实现精准控制与测量,可靠性高,可用于200 kW以下的交流异步电机或永磁同步电机的性能及耐久性测试。

The architectural components of the commonDCbus motor test system based on LabVIEW was introduced, the ASD servo driver with high precision and high dynamic response was adopted, and suitable current sensor and power analyzer were selected. The upper computer LabVIEW and MATLAB combined to drawn the motor MAP figure and external characteristic curve. The upper computer LabVIEW established relationship with the SQL database. The commonDCbus system optimized the energy circulation mode and realized internal circulation of energy on the bus side. According to the test results, the system had comprehensive functions, could achieved precise control and measurement, had high reliability, and could be used in the performance and durability tests of AC asynchronous motor or permanent magnet synchronous motor below 200 kW.
