系统工作循环主系统输人功率的计算见表21-2-27的第8~10栏。根据第10栏的数据绘制的功率循环图见图21-2-5。在工作循环中锁模阶段所用的功率是最大的,为Pmax = 36. 8kW,max但持续时间短,不能按它选择电动机。按表21-2-27第11栏和第7栏的数据求出工作循环周期所需的电动机等值功率为
The calculation of the input power of the main system in the working cycle of the system is shown in columns 8 ~ 10 of Table 21 ≤ 2 ≤ 27. The power cycle diagram drawn according to the data in column 10 is shown in figure 21 / 2 / 5. The power used in the mode-locking phase of the working cycle is the largest, Pmax = 36. 8kW, max but short duration, can not select the motor according to it. According to the data in columns 11 and 7 of Table 21 / 2 / 27, it is found that the equivalent power of the motor required for the working cycle is
