(一) 在用感应电动机驱动的矿井提升设备的设计中是分两步进行的: 1)根据矿井年产量选择提升系统,进行运动学及动力学的计算,在电动机的样本书中选择标准电动机。 2)计算电力驱动装置(起动电阻,接触器………等)。 在第一个步骤的设计中已经确定了运动学。这就表明
(A) In induction motor-driven mine hoist equipment design is carried out in two steps: 1) According to mine annual output to choose to upgrade the system, kinematics and dynamics calculations, select the standard motor sample book motor . 2) Calculate the electric drive (start resistance, contactor ......... etc.). Kinematics has been identified in the design of the first step. This shows
