Wannan motar tana bin ƙa'idodin aiki na linzami kuma saboda wannan yana da sauƙi don cikakken amfani da halayensa idan aka kwatanta da daidaito ko asynchronous Motors.
 
Haɗin Motar DC:
An kafa stator da gawar ƙarfe da maganadiso ɗaya ko fiye waɗanda suke ƙirƙirar filin maganaɗisu na dindindin a cikin stator. A bayan stator akwai abubuwan hawa da burushi wadanda suke bada sadarwar lantarki tare da rotor.The rotor din kansa an kirkireshi ne da wata gawa ta karfe dauke da muryoyi wadanda suke hade da juna a wajan da ke bayan motar. Mai haɗawa da haɗin goge sai zaɓi murfin wanda wutar lantarki ke wucewa ta kishiyar shugabanci.

Saboda haka, motar tana dauke da madaidaitan maganadiso (stator) amoving maganadisu (rotor) da kuma wata gawa ta karfe dan maida hankali ga juyi (jikin motar). (DRW 1)
(DRW 2) Ta hanyar jan hankalin kagaggun sanduna da ƙyamar abubuwa kamar sandunan, to karfin juyi sai yayi aiki a kan rotor ya sanya shi juyawa. Wannan karfin juzu'in yana a kalla yayin da akasarin tsakanin sandunan rotor ya yi daidai da na sandar stator. Da zarar rotor ya fara juyawa, goge goge suna yin katsewa tare da sassan masu juyawa bi da bi. Hakanan an kunna kuzarin rotor sannan a sake kuzari ta irin yadda rotor ya juya, akasarin sabon sandar rotor din koyaushe yana daidai da na stator. Saboda yadda aka tsara fasinja, rotor yana cikin motsi koyaushe, komai matsayin sa. Luarƙirar juzu'i na sakamakon karfin yana raguwa ta hanyar ƙara yawan ɓangarorin masu jigilar kayayyaki, ta haka yana ba da juyawa yadda ya kamata. Ta hanyar juya wutar lantarki ga motar, halin yanzu a cikin rotor coils, sabili da haka sandunan arewa da kudu, ana juyawa. The karfin juyi wanda yayi aiki a kan na'ura mai juyi haka yake juyawa kuma motar ta canza hanyar juyawa. A yanayinta, motar DC motar motsa jiki ce tare da juyawa zuwa juyawa.
 
Karfin juyi da kuma saurin juyawa:

Hanyar ƙarfin ikon fitarwa na motar an cire shi daga jadawalin karfin juyi da sauri. (DRW 2) torarfin ƙarfin vs. hanzari da murfin wutar fitarwa ya dogara da ƙarfin lantarki zuwa motar.
Voltagearfin wutar lantarki ga motar yana ɗaukar ci gaba da gudana na motar a yanayin zafin jiki na 20 ℃ a cikin yanayin aiki mara ƙa'ida.
 
Zai yuwu a samarda motar da wutan lantarki daban-daban (yawanci tsakanin -50% da + 100% na karfin wutan da aka bada shawarar) .Idan anyi amfani da karamin karfin wuta idan aka kwatanta shi da wanda aka bada shawarar motar zata zama mara karfi sosai. An yi amfani dashi, motar zata sami ƙarfin fitarwa mafi girma amma zaiyi aiki da zafi (ana bada shawarar yin aiki akai-akai). 
 
Ga bambance-bambance a cikin wutan lantarki tsakanin kimanin - 25% zuwa + 50%, sabon karfin juzu'i vs. hanzarin jadawalin zai kasance a layi daya da na baya. Harshen farawa da ba saurin lodi zai iya bambanta da kashi daya (n%) kamar yadda bambanci a cikin samar da ƙarfin lantarki. Matsakaicin ƙarfin fitarwa an ninka shi da (1 + η%) 2. 
 
Misali: Don ƙara kashi 20% cikin ƙarfin lantarki
Torarin karfin farawa yana ƙaruwa da 20% (x 1.2)

Wannan karfin juzu'in yana da irin wannan: : C = Kc (I - Io) queunƙwasawa na yankun ƙasa shine Kc. Io Saboda haka an bayyana karfin juyi kamar haka: C = Kc. I - Cf Cf = Kc. Io
Kc = Mai karfin gwiwa (Nm / A) C = karfin juyi (Nm)
