可以理解為，起動時轉子感生電流的磁場與定子磁場的夾角太小。只有達到90°時力矩大，但整個過程都不可達到90°，只是逐步向90°靠近。

如果不改變轉子線圈材料和線槽尺寸，只是改變匝數和線經，那理論上不能改變線圈的電阻與電抗比。比如把1匝擴為10匝，則電阻電抗都擴大到100倍，感生電壓擴大到10倍。

但如果把單匝改多匝，再將線頭引出，串聯上的電阻，就可以改變阻抗比，使起動電流比鼠籠式低，而起動力矩比鼠籠式大。并且調節這個串聯電阻時，可以改變電機的起動和運行性能，這就是繞線轉子異步電機的原理。這種電機多用于難起動機械部位。

由于半導體技術的進步，整流和交流逆變技術成熟了。現在變頻器的出現，能任意調節起動頻率，使得鼠籠式電動也可以代替繞線式了。

繞線型異步電動機的優點是結構簡單、可靠性高、制造成本低。它們廣泛應用于家用電器、工業設備以及交通運輸等領域。
