Tšimong ea enjene e nyane le e mahareng e mehato e meraro e asynchronouss, ho netefatsa polokeho ea ts'ebetso le ts'ebetso ho bohlokoa. E 'ngoe ea litsela tse atlehang ka ho fetisisa tsa ho finyella sepheo sena ke ho sebelisa tšireletso e feteletseng le likarolo tsa tekanyo ea mocheso. Har'a tsona, li-thermistors tsa PTC (poti-coefficient) li fetohile khetho e tummeng ka lebaka la litšobotsi le melemo ea tsona e ikhethang.
Li-thermistor tsa PTC li nyenyane 'me li loketse hantle bakeng sa ho kopanngoa le tsamaiso ea likoloi moo sebaka se fokolang. Matla a bona a tlaase a mocheso a lumella karabelo e potlakileng ea mocheso, e leng se lumellang ho lemoha hoo e batlang e le hang-hang ha maemo a ho chesa haholo. Nako ena ea karabelo e potlakileng e bohlokoa ho thibela tšenyo e ka bang teng ho enjene ka ho lumella ho kenella ka nako pele ho hloleha ho hoholo ho etsahala.
Hase feela hore li-thermitor tsena li sebetsa hantle ho lekola mocheso, li boetse li phetha karolo ea bohlokoa mesebetsing e fapaneng ea ts'ireletso. Hangata li sebelisoa bakeng sa ts'ireletso ea motlakase, overvoltage, le overload ea li-motors. Ka ho tsoela pele ho beha leihlo li-parameter tsa motlakase, li-thermistor tsa PTC li ka tsosa mehato ea ts'ireletso ha li lemoha maemo a ka bakang ho hloleha ha motlakase. Mokhoa ona o sebetsang o thusa ho lelefatsa bophelo ba enjene le ho e boloka e sebetsa hantle.
Ho feta moo, li-thermistor tsa PTC li bapala karolo ea bohlokoa ho ts'ireletso ea karolo ea tahlehelo. Ka karolo e meraro ea asynchronous inductionac motortsamaiso, tahlehelo ea karolo e le 'ngoe e ka baka mathata a tebileng a ts'ebetso, ho kenyelletsa le ho chesa haholo le khatello ea mochine. Ka ho sebelisa li-thermistor tsa PTC, li-motors li ka sireletsoa maemong a joalo, ho netefatsa hore li sebetsa ka har'a maemo a sireletsehileng.
Ke mokhoa o tloaelehileng le o sebetsang oa ho kopanya li-thermistor tsa PTC bakeng sa tšireletso ea mocheso o feteletseng le tekanyo ea mocheso ka li-motor tse nyenyane le tse mahareng tse tharo tsa asynchronous motors. Li nyenyane, li arabela ka potlako, 'me li na le mekhoa e mengata,' me ke likarolo tsa bohlokoa bakeng sa ho netefatsamotlakasetshebetso le bophelo. Ho bohlokoa ho utloisisa likarolo tsena ho mang kapa mang ea amehang moralong oa makoloi, tlhokomelong kapa tšebetsong.
