机调压调速拖动的电梯 ACVV
由于直流调速拖动系统平滑稳定,调速范围宽,因此,容易实现自动化,并在新建厂矿企业广泛应用。
Because of the DC speed governor driving system stability, wide speed control range, easy automatization and it's widely used in new built factory.
电控部分:是控制拖动动平衡机电机的启动和停止及调速的部件,也叫电控箱。
The control part is: control drag balancing machine motor start and stop and speed components, also called electric control box.
但步进电机的效率低,拖动负载的能力不大,脉冲当量不能太大,调速范围不大。
But the step motor efficiency is low, the ability is not big, load drag pulse equivalent cannot too big, speed range is not big.
