浅议变频器的单相电动机调速装置

摘要:

本文简单介绍了单相电动机及变频器的工作原理,而后根据它们的工作原理,参考市场上已存在的变频器,对比单相电容式电动机独有的特点,找到二者之间的关联点及其中相悖之处,加以适当调动,解决问题,从而实现单相电动机的无级调速。然后,通过精密的计算、比较、实验操作,最后得出最终的调速系统。

Based on the inverter motor speed regulating device

Abstract:

This paper briefly introduces the working principle of the single-phase motor and inverter, and then according to their working principle, reference to the market already exist on single phase capacitor motor frequency converter, in contrast to the unique characteristics, to find the correlation between the two points and the contrary, properly solve the problem, thus realizing the mobilization, the single phase motor stepless speed regulation. Then, through precise calculation, comparison, experiment operation, finally reached the final of the speed control system.
