摘要
本文对正在研制的蛇形造波机进行了异步电机变频调速驱动的研究，结果是可行的．文中按照异步电机的型等值电路和变频调速器自动加大Ｕ１ｆ的功能，推导了异步电机变频调速时的传递函数。
In this paper, we discussed if the multi- directional wave generator can be driven by asynchronous motors under frequency control of motor speed. The answer is positive. The transfer function of asynchronous motor under frequency control of motor speed is deduced according to the Г equivalent circuit of asynchronous motor and the function of automatic U 1/ f increased automatically by frequency converters. This is the foundation of the theory in the design.
