Zoo, Common Specifications hais nyob rau npe pla ntawm ib qho hluav taws xob thauj khoom suav nrog nws qhov ntsuas hluav taws xob, ntsuas tam sim no, Lub zog thiab zaus. Yog li cas induction lub cev muaj zog Lwm yam tseem ceeb xws li fais fab, Chav kawm ntawm rwb thaiv tsev, Ambient kub, KVA ntsuas, tsis muaj. ntawm theem, ceev hauv RPM thiab nominal efficiency.

Ib yam nkaus, cov ntaub ntawv dab tsi ntawm daim ntawv tsav tsheb?

Cov ntaub ntawv no qhia koj ntawm qhov voltage qhov twg lub cev muaj zog yog tsim los ua haujlwm. Daim ntawv npe -Definition parameters rau cov lub cev muaj zog xws li lub zog muaj zog, kev ua tau zoo, lub zog thiab qhov tam sim no nyob ntawm qhov ntsuas hluav taws xob thiab zaus. Thaum lub lub cev muaj zog yog siv ntawm lwm qhov hluav taws xob ntau dua li qhov ntsuas hluav taws xob tau qhia hauv npe , nws qhov kev ua tau zoo yuav cuam tshuam.

Tseem Paub, lub hwj chim twg tau hais rau ntawm daim ntawv npe ntawm lub cav? Lub zog nees. Ncej horsepower yog ntsuas ntawm tus cov motor mechanical output rating, nws muaj peev xwm xa cov torque xav tau rau lub load ntawm rated ceev. Feem ntau nws tau muab ua "HP" ntawm daim ntawv npe.

Hais txog qhov no, NEMA lub cev muaj zog ntsuas yog dab tsi?

NEMA hluav taws xob lub cev muaj zog starters hais txog tus txheej txheem kev ntaus nqi system rau hluav taws xob kev ua tau zoo ntawm feem ntau style ntawm American-built lub cev muaj zog pib NEMA pib yog ntsuas los ntawm qhov loj me: 00, 0, 1, 2, 3, 4, 5, 6 thiab 7.

Dab tsi ua rau lub cev muaj zog VFD tau tshaj?

1. Yog cov Tsav yog pre-EPAct (1992), nws yuav tsum tau khiav mus VFDs tsuas yog ua tib zoo xav. Motors ua lub sijhawm ntawd tsis yog ua rau VFD siv, tab sis yog tias lawv yog VFD rated, yuav ok. Class F rwb thaiv tsev los yog siab dua yog haum rau VFD siv, mas VFDs tej zaum yuav tsis muaj ntau tshaj li 2: 1 Constant Torque ratio.
