Emkhakheni we encane nephakathi nendawo enezigaba ezintathu ze-asynchronous motors, ukuqinisekisa ukuphepha nokusebenza kahle kubalulekile. Enye yezindlela eziphumelela kakhulu zokufeza lo mgomo ukusebenzisa ukuvikela ukushisa ngokweqile kanye nezingxenye zokulinganisa izinga lokushisa. Phakathi kwazo, ama-thermistors e-PTC (i-coefficient yokushisa enhle) abe yisinqumo esidumile ngenxa yezimpawu nezinzuzo ezihlukile.
Ama-thermistors e-PTC mancane futhi afaneleka kahle ukuhlanganiswa kumasistimu ezimoto lapho isikhala silinganiselwe. Amandla abo okushisa aphansi avumela ukusabela okusheshayo kwezinga lokushisa, okuvumela ukutholakala cishe ngokushesha kwezimo zokushisa ngokweqile. Lesi sikhathi sokusabela okusheshayo sibalulekile ekuvimbeleni umonakalo ongase ube khona emotweni ngokuvumela ukungenelela okufika ngesikhathi ngaphambi kokuba kwenzeke ukwehluleka okukhulu.
Akukhona nje ukuthi lawa ma-thermistors asebenza kahle ekuqapheni izinga lokushisa, futhi adlala indima ebalulekile emisebenzini ehlukahlukene yokuvikela. Zivame ukusetshenziselwa ukuvikela amandla angaphansi kwamandla, i-overvoltage, nokulayisha ngokweqile kwamamotho. Ngokuqhubeka nokuqapha amapharamitha kagesi, ama-thermistors e-PTC angacupha izinyathelo zokuvikela lapho zithola izimo ezingabangela ukungasebenzi kwemoto. Le ndlela yokusebenza isiza ukunweba impilo yenjini futhi iyigcine isebenza kahle.
Ukwengeza, ama-thermistors e-PTC adlala indima ebalulekile ekuvikelweni kokuqala kokulahlekelwa kwesigaba. Ngokungeniswa kwe-asynchronous kwezigaba ezintathuac motoruhlelo, ukulahlekelwa kwesigaba esisodwa kungabangela izinkinga ezinkulu zokusebenza, kuhlanganise nokushisa nokucindezeleka kwemishini. Ngokusebenzisa ama-thermistors e-PTC, izinjini zingavikelwa ezimweni ezinjalo, kuqinisekiswe ukuthi zisebenza ngaphakathi kwemingcele ephephile.
Kuwumkhuba ovamile futhi osebenzayo ukuhlanganisa ama-thermistors e-PTC ukuze kuvikelwe ukushisa ngokweqile kanye nokukalwa kwezinga lokushisa kumamothoni amancane naphakathi nendawo anezigaba ezintathu ze-asynchronous. Mancane, aphendula ngokushesha, futhi ahlukahlukene, futhi ayingxenye ebalulekile yokuqinisekisamotor kagesiukusebenza kanye nempilo. Ukuqonda lezi zingxenye kubalulekile kunoma ubani ohilelekile ekwakhiweni kwezimoto, ukunakekelwa, noma ukusebenza.
