چکیده
Abstrakt Hlavními požadavky kladenými na pohybové osy NC obráběcích strojů jsou vysoká přesnost polohování a vysoká dynamika pohybů. Základní předpoklad pro dosažení těchto protichůdných předpokladů jsou tuhá a lehká konstrukce mechanické struktury stroje. Těmito parametry je dána výše první antirezonanční frekvence, která omezuje nastavení zesílení kaskádně uspořádaných regulátorů rychlosti a polohy. Na výsledné dynamice a přesnosti pohybu osy NC stroje se přirozeně výraznou měrou podílí přesnost samotného pohybového mechanismu, motoru a zpětnovazebního odměřování pohybové osy. Příspěvek je zaměřen na nerovnoměrnost chodu pohybové osy s prstencovým synchronním motorem s permanentními magnety, který je využíván k přímým pohonům rotačních os NC obráběcích strojů pro pohony otočných stolů, kolíbek a karuselů.
