Kana injini yakavharwa kwenguva yakareba, inopera.Iri idambudziko rinowanzo sangana mukugadzira maitiro, kunyanya kune mota dzinodzorwa ne AC contactors. Ndakaona mumwe munhu ari paInternet achiongorora chikonzero, icho ndechokuti mushure mokunge rotor yakavharwa, simba remagetsi harigoni kuchinjwa kuva magetsi emagetsi uye kupiswa.Zvakati dzikamei. Ngatizvitsanangurirei nemazwi echivanhu, zvekuti kana ukasangana nerudzi urwu pabasa, sabhuku anobvunza kuti nei mota yatsva, pasina kushandisa mazwi evasina basa. Wobva wauya nenzira dzinobvira dzekudzivirira mota kuti isamira, ita shuwa kuchengetedzwa kwemota, chengetedza mari yekambani, uye basa rako richava rakatsetseka. 1. Nzira dzekufambisa motokari dzinotsigira michina dzakasiyana, uye matanho ekudzivirira motokari akasiyana.Kana iyo triangular transmission mota ikasangana nemutoro wakawandisa kana kumira, bhandi retatu rinotsvedza kuchengetedza kuchengetedza kwemota nemidziyo.Iyo simba rekugovera kutonga redunhu rinobva rashandiswa.Thermal relay dziviriro kana yakakosha mota dziviriro. Pane kusanzwisisana apa.Kana mushandi akasangana nedanga nekuda kwezvikonzero zvisingazivikanwi, panzvimbo yekuchenesa midziyo uye kugadzirisa chikonzero chekutengesa, anotanga kakawanda.Sezvo iyo thermal relay yekudzivirira inofamba, kana isingakwanise kutanga, anoigadzirisa pamaoko uye oitanga zvakare, kuitira kuti mota imhanye zvakanyanya.Yakapisa. Mushure mokunge rotor yakavharwa, ikozvino inogona kuwedzera kakawanda kana gumi.Kana iyo yakayerwa ikozvino yemota inopfuura yakawandisa, iyo inotenderedza ichapiswa kunze.Kana kuti inogona kuputsa iyo insulation layer, ichikonzera pfupi pfupi pakati pezvikamu kana pfupi dunhu kune goko. Iyo mota inodzivirira haisi panacea.Kuti udzivise kupisa mota, zvinodikanwa kushandisa chidziviriro uye kunyatsoita yakachengeteka inoshanda mitemo.Kana chinokonzera chigadziko chinosangana, motokari haigoni kushandurwa kakawanda pasina kubvisa chikonzero chechigadziko. Kana iwe uchida kuve nehusimbe uye usachenese michina, kuenderera mberi kwekumanikidza kunopisa mota. 2. Nekuvandudzwa kwetekinoroji, frequency converter control yave yakajairika.Aya epamusoro-tekinoroji ekutonga ane imwezve layer yekudzivirira kana ichienzaniswa ne AC contactor control.Iyo frequency converter inozvidzivirira kubva pakuremerwa kana kupfupika kwedunhu, uye haibvise njodzi dzakavanzika dzekumira kana kupfupika kwedunhu.Kana iwe ukatanga kakawanda Kwete. Saka rudzi urwu rwedunhu harupise mota? Hapana matanho ekudzivirira ane masimba ese.Mushure mekunge inverter yavharwa uye yakagumburwa, mushandisi akangwara kana mugadziri wemagetsi asingazive zvakawanda anogadzirisa zvakananga inverter oitanga zvakare.Mushure memamwe mashoma ekuedza, iyo inverter ichapisa uye inoramba yakaputsika.Iyo frequency converter haigone kudzora mota. Kana kuti kugadzira patsva kunomanikidza akati wandei kutanga, zvichiita kuti mota iwedzere kupisa nekupisa. Naizvozvo, zvakajairika kuti mota dzimire, asi kupisa mota kunoreva kushanda kusina kunaka.Dzivisa kushanda zvisina kunaka kuti usapisa mota. 3. Shanda nesimba pakutonga kwemotokari kuti uone kushanda kwakachengeteka kwemotokari.Iyo inopisa relay uye mota inodzivirira inofanirwa kuongororwa nguva nenguva kuona kana iyo control circuit inogona kubviswa.Pane bhatani dzvuku pane thermal relay.Dzvanya iyo panguva yenguva dzose yekuyedza kuti uone kana ichigona kudzima.Vhura mutsetse. Kana isingakwanisi kubviswa, inofanira kutsiviwa nenguva. Uye zvakare, tarisa kana iyo mota yekudziya relay, iyo yakagadziridzwa kuseta ikozvino uye yakachengetedzwa yakatemerwa mutambo wazvino usati watanga muchina zuva rega rega, uye haigone kudarika iyo mota yakayerwa ikozvino. 4. Kusarudzwa kwemagetsi emagetsi emagetsi kunofanira kunge kwakavakirwa pane yakarongwa ikozvino yemotokari.Haikona kunge yakakurisa.Kana yakakura kwazvo, haizopi kuchengetedzwa kwedunhu pfupi. 5. Dzivirira injini kubva pakupera kwechikamu.Hazvishamisi kuti injini inopisa nekuda kwekushayikwa kwechikamu.Kana manejimendi asiri munzvimbo, zvichaitika nyore.Usati watanga muchina, shandisa multimeter kutarisa magetsi emota kuti uone kana matatu-chikamu voltage ichienderana uye uone kana magetsi ekupa magetsi akajairwa. Mushure mekutanga, shandisa ikozvino clamp mita kuyera matatu-phase ikozvino yemota kuti uone kana yakaenzana.Iwo matatu-chikamu mafungu akafanana uye hapana misiyano yakawanda.Sezvo zvikamu zvitatu zvisingayerwe panguva imwe chete, ikozvino yakasiyana nekuda kwekuremerwa. Izvi zvinogona kubvisa basa rekurasikirwa kwemota kumberi.
