单相电机的电容接线方法图解-单相电容电机有两个绕组，即启动绕组和运行绕组。两个绕组在空间上相差90度。第一种接线方式是“电容运转型"，如图1所示。在这种接法中，辅助起动绕组用于辅助启动，起动转矩相对较小，但运转速率保持稳定。这种接法主要应用于电风扇、空调风扇电动机以及洗衣机等设备。第二种接线方式是“电容起动型"，如图2所示。在这种接法中，电机静止时离心开关接通，给电后起动电容参与起动工作。当转子转速达到额定值的70%至80%时，离心开关会自动跳开，起动电容完成任务并被断开。此时，起动绕组不再参与
单相电机电容接线图和方法220V单相双电容电动机有一个启动电容和一个运行电容。容量较大的是启动电容，容量较小的是运行电容。电动机启动后离心开关将启动电容从电路中断开。如果缺少启动电容，电动机启动困难或无法启动(常表现为空载启动正常，加载后无法启动);如果缺少运行电容，电动机可以启动，但输出功率变小(常表现为带负载能力降低)。一般启动电容是串接在单相电机的启动绕组上，与工作绕组并联。电机静止时接线方法：用万用表测单相电机三个接线端子中的任意两个，可以得到三组数值。电容接阻值最大的两个端子，零火线接阻值小的两个端子(零火线可以互换)。如果电机需要反转，把接电容一端的线换到电容的另外一端即可。

220V交流单相电机起动方式大概分一下几种： 第一种，分相起动式，如图1所示，系由辅助起动绕组来辅助启动，其起动转矩不大。运转速率大致保持定值。主要应用于电风扇，空调风扇电动机，洗衣机等电机。第二种，电机静止时离心开关是接通的，给电后起动电容参与起动工作，当转子转速达到额定值的70%至80%时离心开关便会自动跳开，起动电容完成任务，并被断开。起动绕组不参与运行工作，而电动机以运行绕组线圈继续动作dan xiang dian ji dian rong jie xian tu he fang fa 2 2 0V dan xiang shuang dian rong dian dong ji you yi ge qi dong dian rong he yi ge yun xing dian rong 。rong liang jiao da de shi qi dong dian rong , rong liang jiao xiao de shi yun xing dian rong 。dian dong ji qi dong hou li xin kai guan jiang qi dong dian rong cong dian lu zhong duan kai 。ru guo que shao qi dong dian rong , dian dong ji qi dong kun nan huo wu fa qi dong ( chang biao xian wei kong zai qi dong zheng chang , jia zai hou wu fa qi dong ) ; ru guo que shao yun xing dian rong , dian dong ji ke yi qi dong , dan shu chu gong lv bian xiao ( chang biao xian wei dai fu zai neng li jiang di ) 。yi ban qi dong dian rong shi chuan jie zai dan xiang dian ji de qi dong rao zu shang , yu gong zuo rao zu bing lian 。dian ji jing zhi shi "
