25、單的單相雙建恕組電容式電動機，要靠手工核算其完整的運行特性是相當困難的事，更不用說其它各種復雜的接線方式了。所以，盡管抽頭式調速單相電容式電動機產(chǎn)品早在以前已在美國流行。但是，有關的定量分析計算卻遲遲未見報道。直到70年代，才最初由Cyrl G .V einott在采用計算條件下得以完成。自此以后，隨著計算機在各國普及，從1975一1985年約十年期間，國內外有關抽頭調速的單相電容式電動機性能分析和計算的文章、像雨后春筍一般涌現(xiàn)出來，使

28、傳統(tǒng)上，異步發(fā)電機存在兩大問題①需要靜止勵磁電容器②異步發(fā)電杉喲電壓穩(wěn)定問題這二個問題已隨電容器和電子技術的發(fā)展而被解決。而從單相異步發(fā)電機本身的運行理論來看，以往人}I基于三相異步電機的理論與實踐，認為只要將單相電容式異步電動機的轉子加速，使其超過同步轉速，就自然達到發(fā)電機運行狀態(tài)可是，這種簡單的推論對單相異步發(fā)電機來說是不正確的。根據(jù)這種方式所得的發(fā)電機運行特性很差，這可能也是影響其應用的一個原因。</p><p
