Kev sib raug zoo ntawm lub cev muaj zog zaus thiab ceev
Zaus yog tus naj npawb ntawm cov kev hloov pauv ib ntus ua tiav ib lub sijhawm. Nws yog ib qhov ntau uas piav txog qhov zaus ntawm kev txav mus los. Nws feem ntau sawv cev los ntawm lub cim f lossis ν, chav tsev yog ib-thib ob, thiab lub cim yog s-1. Txhawm rau ua kev nco txog kev koom tes ntawm German physicist Hertz, chav tsev ntawm zaus hu ua Hertz, hu ua "Hertz", thiab lub cim yog Hz.
Cov mis rau xam lub cev muaj zog n yog:
n=60f/p
Hauv cov qauv: n (rev/min) - qhov ceev ntawm lub cev muaj zog;
60 (seconds) - ib feeb;
f (Hertz) - lub zog zaus;
p — Tus naj npawb ntawm cov ncej khub ntawm lub rotating magnetic teb ntawm lub cev muaj zog.
Kev suav cov mis ntawm lub cev muaj zog F:
F=ntau tus ncej khub * ceev / 60,
Tus naj npawb ntawm cov ncej hlau nplaum yog 2 khub, thiab lub cav ceev yog 1500 rpm, yog li qhov zaus F=2*1500/60=50 Hz; Siv peb lub tshuab hluav taws xob hauv tsev ua piv txwv, tus naj npawb ntawm cov hlau nplaum sib nqus yog 1 khub, thiab lub tshuab hluav taws xob teeb nrawm yog 3000 Tig / min, yog li qhov zaus yog F=1*3000/60=50HZ.
Nyob rau hauv cov xwm txheej uas lwm yam kev mob tseem tsis hloov pauv, qhov sib nqus ncej ntau dua ntawm cov hlau nplaum, qhov kev sib hloov qeeb yuav qeeb. (Thaum lub ntsuas hluav taws xob thiab tus naj npawb ntawm stator tig tsis tu ncua, lub zog rov qab electromotive yog proportional rau cov khoom ntawm kev sib hloov ceev thiab tus naj npawb ntawm tus ncej. khub yog qhov yooj yim inversely proportional.) Tus naj npawb ntawm cov sib nqus ncej khub tuaj yeem siv Kho qhov ceev ntawm lub cev muaj zog. Thaum tus naj npawb ntawm cov ncej ncej nce, qhov ceev ntawm lub cev muaj zog txo, tab sis cov zis torque nce; Thaum tus naj npawb ntawm cov ncej khub txo qis, qhov ceev ntawm lub cev muaj zog nce, tab sis cov zis torque txo. Nws yuav tsum tau muab sau tseg tias tus naj npawb ntawm ncej khub kuj cuam tshuam rau lub zog ntawm lub cev muaj zog. Nyob rau hauv high-ceev ntau yam, txo tus naj npawb ntawm ncej khub txo lub hwj chim. Yog li ntawd, thaum tsim ib lub cev muaj zog, nws yog ib qho tsim nyog los xaiv tus naj npawb ntawm cov ncej uas tsim nyog raws li qhov yuav tsum tau ua ntawm daim ntawv thov.
