转子外串电阻的谐波起动电动机及控制线路的设计
摘 要:笼型感应电动机具有结构简单、运行可靠等优点,但起动性能不及绕线型感应电动机,而绕线型感应电动机由于结构型式所决定,具有运行不可靠等缺点。本文介绍一种新型感应电动机,它的设计方案就是针对绕线型和笼型电动机在起动方面所存在的不足,而提出的一种新的解决方案。这种新型电机在结构上具有笼型电机的特点,而在性能上具有绕线型电动机高起动特性等优点,具有结构简单、运行可靠、起动性能好等特点,解决了运行、起动、可靠性三者之间的矛盾,可广泛应用于需要高起动性能的场合。

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.
