Usetyenziso oluninzi lweBLDC lufuna itorque ephezulu.I-torque ephezulu kunye nesantya seempawu ze-DC motors zibavumela ukuba bajamelane ne-torque ephezulu yokumelana, ukufunxa ngokulula ukonyuka komthwalo kunye nokuqhelana nomthwalo ngesantya semoto.Iinjini ze-DC zilungele ukufezekisa i-miniaturization efunwa ngabayili, kwaye zibonelela ngobuchule obuphezulu xa kuthelekiswa nobunye ubuchwephesha beemoto.Khetha i-motor yokuqhuba ngokuthe ngqo okanye i-motor yegiya ngokusekelwe kumandla akhoyo afunekayo, ngokuxhomekeke kwisantya esifunekayo.Izantya ezisuka kwi-1000 ukuya kwi-5000 rpm ziqhuba ngokuthe ngqo i-motor, ngaphantsi kwe-500 rpm i-motor geared ikhethiwe, kwaye i-gearbox ikhethwa ngokusekelwe kwi-torque ephezulu ekhuthazwayo kwindawo ezinzileyo.
Imoto ye-DC iqulethe i-armature yenxeba kunye ne-commutator eneebhrashi ezisebenzisana nemagnethi kwizindlu.Iinjini zeDC zihlala zinesakhiwo esivaliweyo ngokupheleleyo.Banesantya esithe tye se-torque ye-torque ene-torque ephezulu yokuqala kunye nesantya esisezantsi sokungathwali, kwaye banokusebenza kumandla weDC okanye umbane wombane we-AC ngokusebenzisa isilungisi.

Iinjini ze-DC zibekwe kwi-60 ukuya kwi-75 yeepesenti ukusebenza kakuhle, kwaye iibrashi kufuneka zihlolwe rhoqo kwaye zitshintshwe rhoqo kwiiyure ezingama-2,000 ukwandisa ubomi bemoto.Iinjini zeDC zineenzuzo ezintathu eziphambili.Okokuqala, isebenza ngebhokisi yegiya.Okwesibini, inokusebenza kumandla eDC ngokungalawulekiyo.Ukuba ukulungiswa kwesantya kuyafuneka, ezinye izilawuli ziyafumaneka kwaye azibizi xa kuthelekiswa nezinye iintlobo zolawulo.Okwesithathu, kwizicelo ezijonga ixabiso, uninzi lweenjini zeDC lukhetho oluhle.
I-Cogging yeemoto ze-DC ingenzeka ngesantya esingaphantsi kwe-300rpm kwaye inokubangela ilahleko enkulu yamandla kumaza ombane alungisiweyo.Ukuba i-motor geared isetyenzisiwe, i-torque ephezulu yokuqala inokonakalisa isinciphisi.Ngenxa yefuthe lobushushu kwimagnethi, isantya sokungathwali mthwalo siyanda njengoko ubushushu bemoto bukhula.Njengoko i-motor ipholile, isantya siya kubuyela kwisiqhelo kwaye i-torque ye-stall ye-motor "eshushu" iyancitshiswa.Ngokufanelekileyo, ukusebenza okuphezulu kwemoto kuya kwenzeka malunga netorque esebenzayo yemoto.
ukuququmbela
Ukungalungi kweenjini zeDC ziibrashi, zibiza kakhulu ukuzigcina kunye nokwenza ingxolo ethile.Umthombo wengxolo ziibhrashi ezinxibelelana ne-commutator ejikelezayo, kungekuphela nje ingxolo evakalayo, kodwa i-arc encinci eyenziwe xa udibana kunye nokuphazamiseka kwe-electromagnetic.(EMI) yenza “ingxolo” yombane.Kwizicelo ezininzi, iinjini ze-DC ezixutyiweyo zinokuba sisisombululo esithembekileyo.
