Předmět vysvětluje základní stavební bloky elektrického pohonu. Postup návrhu komponent elektrických pohonů, typické zátěžné protimomenty. Dále jsou probrány základní regulační struktury pohonů se stejnosměrnými a střídavými motory a komponenty potřebné pro jejich realizaci jako struktura řídicího počítače, obvody pro přechod z analogových signálů na digitální a realizace samotných regulátorů v digitální formě.
