摘要
以国内第一台 WKP-4变频调速电动挖掘机的应用为例,较深入地介绍了直接转矩控制技术的特性以及与晶闸管供电特性相比较,充分说明了变频调速应用在电动挖掘机上是最理想的传动方式。
Taking the application of the domestic first WKP-4 VVVF excavator for an example, the paper thoroughly introduces the characteristics of direct torque control technology and its comparison with the current supply performance of special thyristor in order to states that frequency control is the most ideal drive style for electric excavators.
