Xyoo 1832, tus Fabkis BiKeXi tau tsim cov cua tshuab dc generator, nws txoj cai yog los ntawm kev hloov cov teeb meem ntawm cov hlau nplaum thiab hluav taws xob electromotive yog raug yuam ua hluav taws xob, thiab lub zog ntawm electromotive hauv daim ntawv ntawm ib qho hluav taws xob DC;
Nyob rau hauv 1866, Siemens ntawm Germany invented nws tus kheej-zoo siab dc generators.
Nyob rau hauv 1869, gramm ntawm Belgium ua ib qhov chaw sib xyaw thiab tsim cov khoom siv hluav taws xob. Qhov no hom generator siv dej zog los hloov lub rotor ntawm lub tshuab hluav taws xob. Tom qab ua kev txhim kho, cov zis zog ntawm 3.2kw tau txais nyob rau hauv 1847.
Nyob rau hauv 1882, Gordon ntawm Tebchaws Mekas tau tsim ib lub 447KW, 3-meter-high, 22-tuj, 2-theem loj generator nrog lub zog ntawm 447KW.
Xyoo 1896, tesla tus ob-theem alternator pib ua hauj lwm hauv lub nyala fais fab nroj tsuag, xa 3750KW, 5000V ntawm kev hloov tam sim no rau twm, 40 kilometers deb.
Westinghouse tsim tsa lub zog nyob hauv Oregon xyoo 1889 thiab tau xa tawm 15,000 volts rau pittsfield hauv xyoo 1892.
