摘要
针对解决传统电机测试系统测试耗时长、过程繁琐、精度低等问题,利用圆筒型双层永磁体空心直线发电机的特殊性能,研究开发了一种直线电机的测试系统。对电机运行进行了效率测试实验,测量了电机运动速度、推拉力、电压等信号,并通过数据的采集、传送装置实现了信号的上传;同时,结合LabVIEW的软件开发平台,检测并记录了信号的实时波形,研究了虚拟仪器技术在电机测试系统中的应用。实验结果表明:该待测直线发电机在速度为350 mm/s,加速度为7 000 mm/s2,负载电阻为196Ω时的运行效率为93.01%,研究结果表明,该电机测试系统拥有较高的可行性和测量精度,为新型待测直线发电机测试系统的设计提供了重要依据。
Aiming at the problems that the traditional motor testing system has the limitation of long time-consuming, tedious process and low precision, a kind of testing system was investigated with special functions of two-layer permanent magnet cylinder linear motor. A motor efficiency experiment was carried out to get the signals of velocity, force and voltage. The signals were uploaded by data acquisition device and data transmission device. LabVIEW was established as software development platform, to keep track of real-time signals and to research virtual instrument technology in the application of motor testing system. The experimental results indicate that the efficiency is 93.01% when the motor velocity is 350 mm/s, the acceleration is 7 000 mm/s^2 and the resistance is 196 Ω. The testing system which has high reliability and measuring precision provides an important basis for the new style motor testing system.
