Ulondolozo lwe-injini lubalulekile ukudlulisela ubomi bomthengisi wakho. Ngapha koko, ukhetho lokuqala lwenjini yasekunene unokwenza umahluko omkhulu kwinkqubo yolondolozo.
Ngokuqonda iimfuno zeTorque kwaye ukhetha iimpawu ezichanekileyo zoomatshini, umntu unokukhetha inqwelo-moya eza kuhlala iminyaka emininzi engaphaya kwewaranti enamanani amancinci.
Umsebenzi ophambili wemoto yombane kukuvelisa i-torque, exhomekeke kumandla kunye nesantya. Umbutho weSizwe woMsebenzi woMbane (i-NEMA) uphuhlise imigangatho yoyilo echaza amandla ombane. Olu candelo lodidi lwaziwa njenge-NEMA LAHLECH kwaye zihlala zineentlobo ezine: A, B, C, no-D.
Ijika ngalinye lichaza i-torque esemgangathweni efunekayo ukuqala, ukukhawulezisa nokusebenza ngemithwalo eyahlukeneyo. Uyilo lwe-NEMA B Motors lugqatselwa njengeziko eliqhelekileyo. Zisetyenziswa kwizicelo ezahlukeneyo apho iqalile iphantsi iphantsi kancinane, apho i-torque ephezulu ayifuneki, kwaye apho akufuneki khona umthwalo onzima.
Nangona uyilo lwe-NEMA B lubandakanya malunga ne-70% yazo zonke iimoto, ezinye iiyilo zeTorque ngamanye amaxesha ziyafuneka.
I-NEMA LIYIYIWEYO KULOLWE B kodwa siye saqala ngoku kunye ne-torque. Yila i-Motors ngokufanelekileyo ukuba isetyenziswe kakuhle nge-RESTEARD Drives (VFDS) ngenxa ye-torque ephezulu eqala xa i-motor isebenza xa i-motor isebenza kwi-qatso iphela ayichaphazeli ukusebenza.
I-NEMA Uyilo C kunye ne-D Ators zithathwa njengeziqatha eziphezulu ze-torque. Zisetyenzisiwe xa i-torque ingakumbi iyafuneka kwangoko kwinkqubo yokuqalisa imithwalo enzima kakhulu.
Umahluko omkhulu phakathi kwe-NEMA C kunye ne-D uyilo sisixa sesantya sesantya semoto. Isantya se-slip semoto esichaphazela ngokuthe ngqo isantya semoto kumthwalo opheleleyo. Imoto ezine, akukho motoli iya kubaleka nge-1800 RPM. Imoto enye eneziliphu ngakumbi ziya kuqhuba nge-1725 i-RPM, ngelixa imoto eneziliphu ezingenakubaleka nge-1780 RPM.
Uninzi lwabavelisi banikezela ngeemoto ezahlukeneyo ezisemgangathweni ezilungiselelwe i-curves ezahlukeneyo zoyilo.
Isixa se-torque esikhoyo kwizantya ezahlukeneyo ngexesha lokuqalisa kubalulekile ngenxa yeemfuno zesicelo.
Abasasazi basebenza izicelo zetota, okuthetha ukuba i-torque yazo ihlala ihleli. Nangona kunjalo, ukuhambisa abaxhasi kufuna into eyongezelelweyo ye-torque yokuqinisekisa ukusebenza rhoqo. Ezinye izixhobo, ezinjengokuqhutywa rhoqo kwe-frequency kunye ne-hydraulic scutches, zinokusebenzisa ukophula i-torque ukuba ibhanti ye-collor ifuna i-torque ngaphezulu kwe-injini inokubonelela.
Enye ye-phenomena enokuchaphazela kakubi ukuqala komthwalo. Ukuba igalelo le-voltageage ihla, i-torque evelisiweyo iphosa kakhulu.
Xa ujonga ukuba i-troque yemoto yanele ukuqalisa umthwalo, kufuneka iqwalaselwe nge-voltage yokuqala. Ubudlelwane phakathi kwe-voltage kunye neTorque ngumsebenzi we-quadratic. Umzekelo, ukuba i-voltage ihla ukuya kwi-85% ngexesha lokuqalisa, imoto iya kuvelisa malunga ne-72% yetotali kwivolthi epheleleyo. Kubalulekile ukuvavanya i-torque yokuqala yemoto ngokunxulumene nomthwalo ophantsi kwemeko embi kakhulu.
Okwangoku, into esebenzayo sisixa sokugcwala okungaphezulu kwenjini yokumelana ngaphakathi kuluhlu lobushushu ngaphandle kokuhamba kakhulu. Kungabonakala ngathi ukuphakama kwexabiso lenkonzo, ngcono, kodwa oku akusoloko kunjalo.
Ukuthenga injini engaphezulu xa kungenakwenziwa ngamandla amakhulu kunokubangela inkunkuma yemali kunye nendawo. Ngokufanelekileyo, i-injini kufuneka iqhubeke ngokuqhubekayo phakathi kwe-80% kunye ne-85% yamandla anqabileyo ukunyusa ukusebenza kakuhle.
Umzekelo, iimotors zihlala zifezekisa ukusebenza kakuhle komthwalo opheleleyo phakathi kwe-75% ne-100%. Ukwandisa ukusebenza kakuhle, isicelo kufuneka sisebenzise phakathi kwe-80% kunye ne-85% yamandla enjini edweliswe kwimephu.
