Uzibuthe omise okwendandandandandandandatho ugxilile ku-DC motor, futhi yamanje idlula ikhoyili ku-rotor ukuze ikhiqize amandla e-ampere. Lapho ikhoyili ku-rotor ihambisana nensimu kazibuthe, isiqondiso samagnetic sizoshintsha uma siqhubeka nokujikeleza. Ngakho-ke, ibhulashi ekugcineni kwe-rotor iguqulwa nge-Amapuleti axhunywe ngokunye, ukuze isiqondiso samanje ku-coil siphinde sishintshe, futhi isiqondiso samandla e-Lorentz akhiqizwayo asishintshi, ngakho-ke i-motor ingaqhubeka ijikeleza ohlangothini olulodwa.
Umgomo wokusebenza weIjeneretha ye-DCowokuguqula amandla e-electromotive akhangwe kukhoyili yengalo yengalo abe amandla e-DC electromotive lapho edonswa umshini ohambayo kusukela ekugcineni kwebhulashi kanye nomthelela wokushintsha webhulashi.
Isiqondiso samandla e-electromotive enziwe sinqunywa ngokomthetho wesandla sokudla (umugqa wendawo kazibuthe ukhomba entendeni yesandla, isithupha sikhomba lapho kuhamba khona umqhubi, kanti eminye iminwe emine ikhomba lapho amandla e-electromotive eyengelwe kumqhubi).
Ukuqondiswa kwamandla kumqhubi kunqunywa umthetho ongakwesokunxele. Leli pheya lamandla kazibuthe kagesi lakha itorque esebenza ku-armature, ebizwa ngetorque kagesi emshinini kagesi ojikelezayo. Isiqondiso se-torque siphambene newashi, emzamweni wokwenza i-armature ijikeleze ngokuphambene newashi. Uma le torque kagesi ingakwazi ukunqoba i-torque yokumelana ku-armature (njenge-torque yokumelana okubangelwa ukungqubuzana namanye ama-torque omthwalo), i-armature ingazungeza iqonde ngokuphambene newashi.
