GENERATOR ARUS SEARAH

Generator arus searah dapat dibagi 2 bagian

utama1. Rotor, yaitu bagian yang berputar.2. Stator, yaitu bagian yang tak berputar.

Fungsi GeneratorUntuk mengubah tenaga mekanik menjadi tenagalistrik.

Prinsip kerjanya(1 !ernenuhi "ukum #ens, yaitu $%rus listrik yang diberikan pada penghantar rotor akan menimbulkanmomen elektro$magnetik yang bersi&at mela'an putaran rotor danseterusnya menimbulkan !F.

(2 )egangan !F yang dibangkitkan menghasilkanarus an kar.
