轉子外串電阻的諧波起動電動機及控制線路的設計
摘 要:籠型感應電動機具有結構簡單、運行可靠等優點,但起動性能不及繞線型感應電動機,而繞線型感應電動機由于結構型式所決定,具有運行不可靠等缺點。本文介紹一種新型感應電動機,它的設計方案就是針對繞線型和籠型電動機在起動方面所存在的不足,而提出的一種新的解決方案。這種新型電機在結構上具有籠型電機的特點,而在性能上具有繞線型電動機高起動特性等優點,具有結構簡單、運行可靠、起動性能好等特點,解決了運行、起動、可靠性三者之間的矛盾,可廣泛應用于需要高起動性能的場合。

Design of A.C. Induction Motor With High Starting Performance
ABSTRACT:The cage induction motor has the advantages of simple structure and reliable operation, etc., but its starting performance is not better than that of wound-rotor induction motor. The later has shortcoming of unreliable operation, etc., depending on the type of its construction. The paper introduces a novel induction motor, which has advantages of simple structure, reliable operation and good starting performance, etc.. and is widely suitable for the device which needs high starting performance. In example it is indicated that calculate the starting resistance by numerical method in the cases of high starting condition necessary.
