1 变频调速技术概述
1.1 基本理论知识
目前我国在应用先进的变频调速技术时,虽然已经对各种技术成果进行了应用,但是以电机学为基础,相关人员在对电机学知识进行具体分析后能够得知,如果某定子绕组在电机内的磁极对数已经给定,那么如果对转速进行改变,就必须要采用有效的方法来改变电源频率,通常来说,电源频率越大其转速就越大,两者的关系成正比;相反的,在拖动电机期间如果电机转速降低了,那么就可以适当的对电源频率进行降低。因此,相关人员需要同时调节和改变电源频率和电机转速[1]。
1.2 变频调速技术带来的好处
以往在拖动电机的过程中,通常会借助自留模式来驱动电机,例如在生产煤矿期间,会对用到大量的点击。……
