三相电机改单相接法-基础知识-技术摇篮http://www.y007.com
http://www.y007.com/diangongjishu/HTML/95631.html
适合1kw一下的 1kw以上的的另计算 还得加上启动电容 变成单项后功率是原来的70. ２ 三相绕组的星形连接 将电容器接在任意两个端子上 如图３中接Ｖ１、Ｕ１ ，２２０Ｖ市电则加在余下的端子Ｗ１和电容Ｃ的任一端上。 ２ 电容器的容量选择 小型三相异步电动机作单相运行时，所选电容容量一定要合适，若太小则旋转无力，启动困难 太大则回路电流过大，导致电机过热。 如果不查表，也可以按经验公式获得 当星形连接时，所需电容容量Ｃ Μｆ Ｐ Ｗ １７，Ｃ的单位是μＦ，Ｐ的单位是Ｗ 当用作三角形连线时，所选电容容量Ｃ μＦ Ｐ Ｗ １０。 根据实践移相电容的容量数值上应约等于0.07与电动机功率之积，如电动机功率为150瓦，所选电容器的容量应约等于0.07 x 150=10.5微法，用两个日光灯电容器 4.75μF)并联即可满足要求。 电容C2的容量可按下式计算 C2=1950*In/(Un*COSФ) (μF) 式中1N、UN、cos十分别是原三相电机铭牌上的额定电流、额定电压和功率因数值，若铭牌上无功率因数，cosy可取0 85左右。

看到 中外缝制设备 2007年第4期中袁亮先生的 三相电机改单相电机的技巧 一文所说的三相电机改单相电机的改法后，感觉如果那样改会造成电机无力、易发热、不易启动等毛病，虽然换了小皮带轮，把皮带放松了，但也好不了多少，只能勉强维持。 当用原有的星形接法改单相时 图2 ，即接通单相电源时，B、C端的电压为220V，A端接电容为滞后120 ，按照三相电压是单相的3倍，即1、2、3三相每组线圈电压仅为130V左右，这样就造成供电电压大大低于电机线圈的额定电压，造成电机线圈所产生的磁场力矩大为减少，而使电机产生无力、发热、不易启动等原因。 针对上述原因，笔者想到改变电机内部接线方法，即改为三角形接法 图3 ，图中A、B、C三端接进电压为220V，但1、2、3三组每组线圈间的电压为220V，这样改装电机的功率会大大提高，足够带动缝制设备运转，而不会产生电机无力、发热、不易启动等现象 注 三角形接法和星形接法在三相电机线圈的电压比为3。 电话 057588059466 传真 057588059466 手机 (0)13575502166.
