Kwintsimi ye encinci kunye nobukhulu obuphakathi kwisigaba sesithathu se-asynchronous motors, ukuqinisekisa ukhuseleko lokusebenza kunye nokusebenza kakuhle kubalulekile. Enye yezona ndlela zisebenzayo zokufezekisa le njongo kukusebenzisa ukhuseleko lobushushu kunye namacandelo okulinganisa ubushushu. Phakathi kwabo, i-PTC (i-coefficient yokushisa echanekileyo) i-thermistors ibe yinto ethandwayo ngenxa yeempawu zabo ezizodwa kunye neenzuzo.
Ii-thermistors ze-PTC zincinci kwaye zikulungele kakuhle ukudityaniswa kwiinkqubo zeemoto apho indawo incinyiwe. Umthamo wabo ophantsi we-thermal uvumela ukuphendula ngokukhawuleza kweqondo lokushisa, okuvumela ukufunyanwa ngokukhawuleza kweemeko zokushisa. Eli xesha lokuphendula ngokukhawuleza libalulekile ekuthinteleni umonakalo onokuthi ubekho kwi-motor ngokuvumela ungenelelo ngexesha ngaphambi kokuba kwenzeke ukusilela okukhulu.
Akunjalo kuphela ezi thermitors ezisebenzayo ekubekeni iliso kwiqondo lokushisa, zidlala indima ebalulekileyo kwimisebenzi eyahlukeneyo yokukhusela. Zihlala zisetyenziselwa ukungabikho kwamandla, ukugqithisa, kunye nokukhuselwa kokugqithiswa kweemoto. Ngokuhlala ebeka iliso kwiiparamitha zombane, i-PTC thermistors inokubangela amanyathelo okukhusela xa ibona iimeko ezinokubangela ukusilela kweemoto. Le ndlela isebenzayo inceda ukwandisa ubomi benjini kwaye igcine isebenza ngokufanelekileyo.
Ukongeza, ii-thermistors ze-PTC zidlala indima ebalulekileyo ekulahlekeni kwesigaba sokuqala ukhuseleko. Kwinqanaba lesithathu le-asynchronous inductionac motorinkqubo, ukulahleka kwesigaba esinye kunokubangela iingxaki ezinzulu zokusebenza, kubandakanywa nokushisa kunye noxinzelelo lomatshini. Ngokusebenzisa i-PTC thermistors, ii-motor zinokukhuselwa kwiimeko ezinjalo, ukuqinisekisa ukuba zisebenza ngaphakathi kweeparamitha ezikhuselekileyo.
Kuyindlela eqhelekileyo kunye nesebenzayo ukudibanisa i-PTC thermistors yokukhusela ukushisa kunye nokulinganisa ubushushu kwiimotor ezincinci kunye nezigaba ezintathu ze-asynchronous motors. Zincinci, ziphendula ngokukhawuleza, kwaye zinezinto ezininzi, kwaye ziyinxalenye ebalulekileyo yokuqinisekisainjini yombaneukusebenza kunye nobomi. Ukuqonda la macandelo kubalulekile kuye nabani na obandakanyeka kuyilo lwemoto, ukugcinwa, okanye ukusebenza.
