Zombini amandla ombane kunye namandla obushushu kufuneka abe ne-exciter. I-exciter ixhunywe ngokubanzi kwi-shaft enkulu efanayo njengejeneretha. Xa i-shaft enkulu ijikeleza phantsi kwe-drive ye-prime mover, iqhuba ngexesha elifanayo i-generator kunye ne-exciter ukujikeleza. I-exciter yi-DC generator ekhupha amandla e-DC, ethunyelwa kwi-coil ye-rotor ngokusebenzisa i-ring slip ye-rotor ye-generator ukuvelisa i-magnetic field kwi-rotor, ngaloo ndlela ivelisa amandla okwenziwa kwi-stator ye-generator. I-exciter yesethi enkulu yejeneretha ithathelwa indawo yinkqubo yokuvuselela i-AC ye-self-shunt, ininzi yayo isebenzisa i-voltage ye-generator outlet ukudlula utshintsho lokuvuselela, ukudlula kwisixhobo sokubuyisela kwi-current ngqo, kwaye emva koko uthumele i-current ngokusebenzisa i-rotor slip ring. kwi-rotor yejeneretha. Xa olu hlobo lwenkqubo lusetyenziswa, ukukhuthazwa kokuqala kwejenereyitha kufuneka kuqhutywe rhoqo xa ivuliwe, oko kukuthi ukongeza i-excitation yokuqala kwi-generator ukuseka umbane wokuqala we-generator.
I-exciter ye-exciter yakudala ixhomekeke kwi-remanence yayo, enokwenza ukuba i-exciter ivelise umbane, kodwa amandla amancinci kakhulu kwaye i-voltage ibuthathaka kakhulu, kodwa lo mbane ubuthathaka udlula kwi-coil yokuvuselela i-exciter ukuqinisa i-remanence. isiphumo. Lo mmandla womeleziweyo wemagnethi uyaqhubeka nokwenza i-exciter ivelise umbane, amandla angaphezulu kunentsalela yokuvelisa amandla umazibuthe, aze aphindaphinde oku ngokuphindaphindiweyo, i-voltage ekhutshwa yi-exciter ingaba phezulu kwaye iphezulu, oko kukuthi, umbane okhutshwe yi-exciter kuqala ngokwawo. Isetyenziselwa ukuseka isakhono sayo, kwaye ibonelele kuphela i-excitation ye-generator xa umbane othile ophezulu ufikeleleke. Inkqubo yokuvuselela iiseti zejenereyitha ezinkulu zanamhlanje yamkela inkqubo yokuvuselela i-microcomputer, kwaye ukuvuswa kwayo kokuqala kubonelelwa ngumbane wokuqala wokuvuselela amandla, obonelelwa yigridi yamandla okanye yi-DC unikezelo lwamandla ombane.
