摘要
介绍SPWM变频调速技术,分析了起重机起升机构的变频调速技术,通过选择变频器TVF1075-G-33,利用交流电机驱动的起重机模型针对起升机构做了变频调速实验,通过系统参数的测试分析,指出变频调速改善了调速系统的转矩输出和速度的平滑调节,证明了SPWM变频调速技术提高了起重机调速系统的性能。
This article introduces SPWM frequency conversion technology and the analysis of this technology used in hoist outfit of crane. In the experiment of frequency conversion text of the crane modol with al- ternating current machine, using the TVF1075-G-33 transducer, it elicits the system parameters. From those parameters this article points the improvement of the speed-governing system. It brings the stepless regu- lation of torque output and speed.
