A variable speed motor iyinjini kagesi ekwazi ukushintsha isivinini sayo ngokuzenzakalelayo noma ngesandla njengoba kudingeka. Isivinini singashintshwa ngokulungisa i-voltage yokuphakelwa kwamandla, ukushintsha i-current, ukushintsha imvamisa noma ukushintsha inkambu ye-electromagnetic.
Izinzuzo eziyinhloko zamamotho okulawula isivinini e-YUSIN AC ukonga amandla nokuncipha kokuguga kwemishini. Ngokulungisa isivinini, injini ingasebenza endaweni esebenza kahle kakhulu, ngaleyo ndlela yehlise ukusetshenziswa kwamandla kanye nezikweletu zikagesi. Ukwengeza, izinjini zejubane eziguquguqukayo ziphinde zehlise ukuguga phakathi kwezingxenye eziwumshini, ngaleyo ndlela andise impilo yezisetshenziswa.
Kunezindlela ezimbili zokulawula isivinini ze-YUSIN AC injini yokulawula isivinini: ukulawulwa kwesivinini sokumelana ne-rotor kanye nokulawulwa kwesivinini sokuguqula imvamisa. Ukulawulwa kwejubane lokumelana ne-rotor kushintsha isivinini semoto ngokushintsha ukumelana ne-rotor, kuyilapho ukulawulwa kwesivinini sokuguqula imvamisa kushintsha isivinini semoto ngokushintsha imvamisa yamandla. Ukulawulwa kwesivinini sokuguqula imvamisa kunokulawula ukusebenza kahle kanye nokunemba okungcono, ngakho-ke sisetshenziswa kakhulu embonini yesimanje.
Kalula nje, amamotho alawula isivinini i-YUSIN AC ayingxenye ebaluleke kakhulu embonini yesimanje, izinzuzo zokonga amandla, ukunciphisa ukuguga kanye nokwenza ngcono ukusebenza kahle, futhi kungaletha izinzuzo ezinkulu ekukhiqizweni kwezimboni.
