Mumunda we diki uye nepakati-saizi matatu-chikamu asynchronous motas, kuve nechokwadi chekuchengetedzwa kwekushanda uye kushanda zvakanaka kwakakosha. Imwe yedzakanyanya nzira dzekuzadzisa chinangwa ichi ndeyekushandisa overheat kudzivirira uye tembiricha kuyerwa zvikamu. Pakati pavo, PTC (positive tembiricha coefficient) thermistors yave yakakurumbira sarudzo nekuda kweakasarudzika maitiro uye zvakanakira.
PTC thermistors idiki uye yakanyatso kuenderana nekubatanidzwa mumamotor masisitimu uko nzvimbo yakaganhurirwa. Kupisa kwavo kwakaderera kunobvumira kukurumidza kupindurwa kwekushisa, zvichiita kuti pave nekukasira kuonekwa kwemamiriro ekupisa. Iyi inokurumidza kuita nguva yakakosha mukudzivirira kukuvara kungangoita mota nekubvumira kupindira panguva kusati kwaitika kukanganisa kwakakomba.
Kwete chete aya ma thermistors anoshanda mukutarisa tembiricha, anoitawo basa rakakosha muakasiyana ekudzivirira mabasa. Iwo anowanzo shandiswa kune undervoltage, overvoltage, uye overload kuchengetedzwa kwemamota. Nekuenderera mberi nekutarisa ma parameter emagetsi, PTC thermistors inogona kukonzeresa matanho ekudzivirira kana yaona mamiriro anogona kukonzera kutadza kwemota. Iyi proactive nzira inobatsira kuwedzera hupenyu hwemota uye kuichengeta ichishanda nemazvo.
Pamusoro pezvo, PTC thermistors inoita basa rakakosha mukurasikirwa kwekutanga kuchengetedzwa. Muchikamu chetatu-asynchronous inductionac motasystem, kurasikirwa kwechimwe chikamu kunogona kukonzera matambudziko makuru ekushanda, kusanganisira kupisa uye kushushikana kwemagetsi. Nekushandisa PTC thermistors, mota dzinogona kuchengetedzwa kubva mumamiriro ezvinhu akadaro, kuve nechokwadi kuti dzinoshanda mukati medziviriro dzakachengeteka.
Iyo yakajairika uye inoshanda tsika yekubatanidza PTC thermistors yekudzivirira kwekupisa uye kuyerwa kwekushisa mumadiki uye epakati-saizi matatu-chikamu asynchronous motors. Izvo zvidiki, zvinokurumidza-mhinduro, uye zvakasiyana-siyana, uye zvakakosha zvikamu zvekuve nechokwadimota yemagetsikuita uye hupenyu. Kunzwisisa zvikamu izvi kwakakosha kune chero munhu ane chekuita nekugadzira mota, kugadzirisa, kana kushanda.
