摘要
机床丝筒电动机的控制方式通常采用继电器控制,但采用此方式控制存在一系列弊端。变频器是通过对交流电频率的控制,达到控制电动机转速的目的。本方法充分利用了变频器的功能特点,实现起来线路简单,可维护性好。
Relay is usually used in electrical motor＇ s control. But it has some shortcomings. Transducer is used to control the speed of electrical motor by changing the frequency of AC. This method takes full advantage of the characters of transducer, thus it is simple of realization and maintenance.
