當(dāng)繞線轉(zhuǎn)子式電機(jī)剛起動(dòng)時(shí),轉(zhuǎn)子尚未轉(zhuǎn)動(dòng),定子繞組產(chǎn)生的旋轉(zhuǎn)磁場高速旋轉(zhuǎn),轉(zhuǎn)子繞組相對(duì)高速切割磁場,產(chǎn)生頻率高幅度也高的感生電壓,轉(zhuǎn)子回路的頻敏電阻器呈現(xiàn)高阻抗,降低起動(dòng)電流;轉(zhuǎn)子旋轉(zhuǎn)起來以后,隨著轉(zhuǎn)差率的降低,轉(zhuǎn)子繞組切割磁場的相對(duì)速度降低,轉(zhuǎn)子感生電壓頻率及幅度也降低;頻敏電阻器呈現(xiàn)低阻抗;起動(dòng)完成后,轉(zhuǎn)差率接近于0,轉(zhuǎn)子感生電壓頻率亦接近于0,頻敏電阻器阻抗接近于0,相當(dāng)于短接轉(zhuǎn)子繞組(實(shí)際使用時(shí)電機(jī)啟動(dòng)完成后直接切除),電機(jī)正常運(yùn)轉(zhuǎn)。
