Izinhlelo eziningi ze-BLDC zidinga itorque yokuqala ephezulu.I-torque ephezulu kanye nezici zejubane zama-motor e-DC ziwavumela ukuthi abhekane ne-torque ephezulu yokumelana, amunca kalula ukwanda okungazelelwe komthwalo futhi azivumelanise nomthwalo ngejubane lemoto.Amamotho e-DC alungele ukufeza i-miniaturization efiswa abaklami, futhi anikeza ukusebenza kahle okuphezulu uma kuqhathaniswa nobunye ubuchwepheshe bezimoto.Khetha i-direct drive motor noma igiya motor ngokusekelwe emandleni atholakalayo adingekayo, kuye ngesivinini osifunayo.Isivinini sisuka ku-1000 siye ku-5000 rpm sishayela imoto ngokuqondile, kukhethwa i-motor egiyelwe ngaphansi kuka-500 rpm, futhi i-gearbox ikhethwa ngokusekelwe ku-torque ephezulu enconywayo esimweni sokuzinza.
Imoto ye-DC iqukethe i-armature yesilonda kanye ne-commutator enamabhulashi asebenzisana nozibuthe endlini.Ama-DC motors ngokuvamile anesakhiwo esivaliwe ngokuphelele.Anejika eliqondile le-torque ene-torque ephezulu yokuqala nejubane eliphansi elingalayishi, futhi angasebenza ngamandla e-DC noma kalayini we-AC ngokusebenzisa isilungisisi.

Amamotho e-DC akalwe ekusebenzeni kahle kwamaphesenti angama-60 kuye kwangama-75, futhi amabhulashi kufanele ahlolwe njalo futhi ashintshwe njalo emahoreni ayi-2,000 ukuze kwandiswe impilo yemoto.Ama-DC motors anezinzuzo ezintathu eziyinhloko.Okokuqala, isebenza nge-gearbox.Okwesibili, ingasebenza ngamandla e-DC ngokungalawuleki.Uma ukulungiswa kwesivinini kudingekile, ezinye izilawuli ziyatholakala futhi azibizi uma kuqhathaniswa nezinye izinhlobo zokulawula.Okwesithathu, kwizicelo ezizwela intengo, amamotho amaningi e-DC ayisinqumo esihle.
Ukuxhunywa kwamamotho e-DC kungenzeka ngesivinini esingaphansi kuka-300rpm futhi kungabangela ukulahleka kwamandla okuphawulekayo kuma-voltages alungisiwe amagagasi agcwele.Uma kusetshenziswa i-motor geared, i-torque ephezulu yokuqala ingalimaza isinciphisi.Ngenxa yomphumela wokushisa kozibuthe, ijubane lokungalayishi liyakhula njengoba izinga lokushisa lemoto likhula.Njengoba i-motor iphola, ijubane lizobuyela esimweni esijwayelekile futhi i-torque ye-stall ye-motor "eshisayo" iyancishiswa.Ngokufanelekile, ukusebenza kahle okuphezulu kwe-motor kuzokwenzeka eduze kwe-torque yokusebenza ye-motor.
Ekuphetheni
Ububi bama-DC motors amabhulashi, ayabiza ukuwanakekela nokwenza umsindo othile.Umthombo womsindo amabhulashi axhumene nesihambisi esijikelezayo, hhayi umsindo ozwakalayo kuphela, kodwa i-arc encane ekhiqizwa lapho kuthintana kanye nokuphazamiseka kukazibuthe.(EMI) yakha “umsindo” kagesi.Ezinhlelweni eziningi, ama-DC motors axutshwe angaba yisixazululo esithembekile.
