Current-ka usha waa dhibaato caadi ah oo aan laga fursan karin oo ku dhacda matoorada danab-sare iyo matoorada soo noqnoqda ee doorsooma. Current-ka usha wuxuu sababi karaa dhaawac weyn nidaamka qaboojinta ee matoorka. Sababtan awgeed, soosaarayaal badan oo matoor ah ayaa adeegsada nidaamyada qaboojinta ama tallaabooyinka ka hortagga si looga fogaado dhibaatooyinka current-ka usha. Soo saarista current-ka usha waxaa sabab u ah marinka qulqulka magnetic-ka ee waqtiga kala duwan iyada oo loo marayo wareegga ka kooban usha matoorka, qaboojinta, iyo qolka qaboojinta, kaas oo kiciya danab-jilicsan usha oo dhaliya hadda marka wareegga la shido. Waa dhacdo jireed oo danab-hoosaad leh, oo hadda sare leh oo sababa dhaawac weyn nidaamka qaboojinta matoorka wuxuuna burburin doonaa qaboojinta muddo gaaban gudahood sababtoo ah nabaad-guurka elektarooniga ah. Feeraha xudunta matoorka waa xaashi qaab taageere ah oo leh godad la dhigay saldhigga. Xudunta kala qaybsan ee matoorka weyn iyo is-dhexgalka rotor-ka ayaa ah qodobbada ugu muhiimsan ee soo saarista current-ka usha. Sidaa darteed, current-ka usha wuxuu noqdaa dhibaatada ugu weyn ee matoorada waaweyn.
Si looga fogaado dhibaatada hadda ee usha, tallaabooyinka lagama maarmaanka ah waa in la qaado marka la dooranayo iyo la naqshadeynayo qaybaha iyo qaybaha si aragti ahaan looga takhaluso arrimaha dhaliya hadda ee usha. Tirada tollooyinka S ee ku yaal wareegga waxaa xakameeya oo hagaajiya xiriirka ka dhexeeya S iyo qaybiyaha ugu weyn ee caadiga ah ee tirada lammaanayaasha usha matoorka. Marka S/t uu yahay tiro siman, shuruudaha lagu soo saaro danabka usha lama buuxiyo, dabiici ahaanna ma jiri doono hadda usha; marka S/t uu yahay tiro aan caadi ahayn, waxay u badan tahay in danabka usha la soo saaro, oo hadda usha la soo saaro. Xitaa haddii noocan matoorku yahay matoor soo noqnoqda oo warshadeed, waxaa jiri doona dhibaatooyin hadda usha la soo saaro. Sidaa darteed, matoorrada waaweyn, guud ahaan waxaa la qaadaa tallaabooyin lagu ilaalinayo hadda usha.
Intaa waxaa dheer, iswaafajinta heerka sare ah ee matoorada soo noqnoqda ee isbeddelka leh ayaa sidoo kale ah mid ka mid ah sababaha qulqulka shafka. Iyadoo aan loo eegin sida matoorka soo noqnoqda ee isbeddelka leh uu u awood badan yahay, waxaa jiri kara qulqulka shafka, sidaa darteed matoorro badan oo soo noqnoqda oo isbeddela oo awood yar leh ayaa isticmaali doona biinanka dahaaran, halka matoorada awoodda sare leh badankood ay isticmaali doonaan daboollada dhammaadka ee dahaaran, ama waxay qaadi doonaan cabbirro dahaaran booska qaadista shafka; si loo hubiyo iswaafajinta matoorada soo noqnoqda ee isbeddelka leh iyo qaybaha matoorada soo noqnoqda ee warshadaha ee caadiga ah, soosaarayaasha qaar ayaa qaadi doona tallaabooyin ka gudub ah booska daboolka shafka.
