输送机启动时,因需要的短时功率比较大,需要电动机2全部投入运转;此时,智能控制装置1忽略电流数据,经过t1秒左右时间延时(t1大小根据输送机不同而不同,通常选取秒到400秒之间),待输送机运转平稳后,再根据电流值进行控制;当电流表将测得的电流值上传至智能控制装置1的采集模块后,由智能控制装置1对测得值与设定电流值A1进行比较,若测得值小于设定值A1,说明电动机利用率较低,此时由智能控制装置1发出减电机指令,电动机2停止运行,超越离合器5分离,与该电机连接的液力耦合器3、减速器4同时停止运转;若测得值大于设定值A1,则电动机2维持原状态运行;在减电机运行过程中,电流表随时检测电动机2的电流值,当由于负荷增加导致电流值增大到大于设定值A2时,被减掉的电机将重新投入运行。
