三、凸轮控制器控制线路

中、小容量绕线转子异步电动机的启动、调速及正反转控制，常常采用凸轮控制器来实现，以简化操作，如桥式起重机上大部分采用这种控制线路。目前三十五页\总数四十四页\编于十二点L1L2L3M3～QSI＞I＞AC8AC9AC7AC6AC5SA10SA11SA12SA1SA2SA3SA4SA5SA6SA7SA8SA954321012345反转零位正转KA1SB2SB1AC12SQ1SA10KMKA2AC10SQ2AC11ACFU1FU1KA1KA2AC1AC4AC2AC3电路组成分析KMKM目前三十六页\总数四十四页\编于十二点正转目前三十七页\总数四十四页\编于十二点L1L2L3M3～QSI＞I＞AC8AC9AC7AC6AC5SA10SA11SA12SA1SA2SA3SA4SA5SA6SA7SA8SA954321012345反转零位正转KA1SB2SB1AC12SQ1SA10KMKA2AC10SQ2AC11ACFU1FU1KA1KA2AC1AC4AC2AC3合上QS,按下SB1KMKM目前三十八页\总数四十四页\编于十二点L1L2L3M3～QSI＞I＞AC8AC9AC7AC6AC5SA10SA11SA12SA1SA2SA3SA4SA5SA6SA7SA8SA954321012345反转零位正转KA1SB2SB1AC12SQ1SA10KMKA2AC10SQ2AC11ACFU1FU1KA1KA2AC1AC4AC2AC3KM触头闭合KMKM目前三十九页\总数四十四页\编于十二点L1L2L3M3～QSI＞I＞AC8AC9AC7AC6AC5SA10SA11SA12SA1SA2SA3SA4SA5SA6SA7SA8SA954321012345反转零位正转KA1SB2SB1AC12SQ1SA10KMKA2AC10SQ2AC11ACFU1FU1KA1KA2AC1AC4AC2AC3手轮转到“正”１位置KMKM目前四十页\总数四十四页\编于十二点L1L2L3M3～QSI＞I＞AC8AC9AC7AC6AC5SA10SA11SA12SA1SA2SA3SA4SA5SA6SA7SA8SA954321012345反转零位正转KA1SB2SB1AC12SQ1SA10KMKA2AC10SQ2AC11ACFU1FU1KA1KA2AC1AC4AC2AC3手轮转到“正”２位置KMKM目前四十一页\总数四十四页\编于十二点L1
