1. Kev cia siab rau lub cev muaj zog: rotational motion
Lub cev muaj zog feem ntau yog hais txog lub cev muaj zog uas tau txais lub zog ntawm lub zog hluav taws xob, thiab feem ntau yog hais txog lub cev muaj zog uas tau txais kev sib hloov.(Nws kuj tseem muaj lub cev muaj zog uas tau txais kev txav ncaj, tab sis peb yuav tawm ntawm lub sijhawm no.)

Yog li, hom kev sib hloov twg koj xav tau?Koj puas xav kom nws tig lub zog zoo li lub laum, lossis koj puas xav kom nws tig tsis muaj zog tab sis ntawm kev kub ceev zoo li lub kiv cua hluav taws xob?Los ntawm kev tsom mus rau qhov sib txawv ntawm qhov xav tau kev hloov pauv, ob lub zog ntawm kev sib hloov ceev thiab torque ua qhov tseem ceeb.

2. Lub zog
Torque yog lub zog ntawm kev sib hloov.Chav tsev ntawm torque yog N·m, tab sis nyob rau hauv cov ntaub ntawv ntawm me me motors, mN·m feem ntau yog siv.

Lub cev muaj zog tau tsim nyob rau hauv ntau txoj kev los ua kom torque.Qhov ntau lem ntawm cov hlau electromagnetic, qhov ntau dua qhov torque.
Vim hais tias tus naj npawb ntawm winding yog txwv los ntawm qhov loj me me, enamelled hlau nrog ib txoj kab uas hla loj dua yog siv.
Peb brushless lub cev muaj zog series (TEC) nrog 16 hli, 20 hli thiab 22 hli thiab 24 hli, 28 hli, 36 hli, 42 hli, 8 yam ntawm 60 hli sab nraud txoj kab uas hla.Txij li thaum lub coil loj kuj nce nrog lub cev muaj zog txoj kab uas hla, siab dua torque yuav tau.
Cov hlau nplaum muaj zog yog siv los tsim cov torque loj yam tsis hloov qhov loj ntawm lub cev muaj zog.Neodymium hlau nplaum yog cov hlau nplaum ruaj khov tshaj plaws, ua raws li cov hlau nplaum samarium-cobalt.Txawm li cas los xij, txawm tias koj tsuas yog siv cov hlau nplaum muaj zog, lub zog sib nqus yuav tawm ntawm lub cev, thiab lub zog sib nqus nqus yuav tsis ua rau lub zog.
Txhawm rau kom tau txais txiaj ntsig zoo ntawm cov hlau nplaum muaj zog, cov khoom siv ua haujlwm nyias hu ua electromagnetic steel phaj yog laminated los txhim kho qhov sib nqus Circuit Court.
Ntxiv mus, vim hais tias lub zog sib nqus ntawm samarium cobalt hlau nplaum yog ruaj khov rau qhov kub thiab txias, kev siv cov hlau nplaum samarium cobalt tuaj yeem ruaj khov tsav lub cev muaj zog hauv ib puag ncig nrog kev hloov pauv kub lossis kub kub.

3. Ceev (revolutions)
Tus naj npawb ntawm cov kiv puag ncig ntawm lub cev muaj zog feem ntau hu ua "speed".Nws yog qhov ua tau zoo ntawm pes tsawg zaus lub cev muaj zog tig ib lub sijhawm.Txawm hais tias "rpm" feem ntau yog siv los ua kev hloov pauv ib feeb, nws kuj tau hais tias "min-1" hauv SI system ntawm units.

Piv rau torque, nce tus naj npawb ntawm revolutions tsis yog technically nyuaj.Tsuas yog txo tus naj npawb ntawm cov lem nyob rau hauv lub kauj kom nce tus naj npawb ntawm lem.Txawm li cas los xij, txij li lub zog torque txo qis thaum tus naj npawb ntawm cov kiv puag ncig nce, nws yog ib qho tseem ceeb kom ua tau raws li ob qho tib si torque thiab kiv puag ncig.

Tsis tas li ntawd, yog tias siv high-speed, nws yog qhov zoo tshaj plaws los siv cov pob bearings es tsis yog cov kabmob dawb.Qhov siab dua qhov ceev, qhov ntau dua qhov kev sib txhuam tsis zoo, lub neej luv ntawm lub cev muaj zog.
Nyob ntawm qhov tseeb ntawm cov ncej, qhov siab dua, qhov ntau dua qhov teeb meem ntawm kev vibration.Vim hais tias lub cev muaj zog txhuam tsis muaj txhuam los yog lub commutator, nws ua suab nrov thiab kev vibration tsawg dua li lub cev muaj zog txhuam (uas tso cov txhuam hniav sib cuag nrog lub rotating commutator).
Kauj Ruam 3: Loj
Thaum nws los txog rau lub cev zoo tagnrho, qhov loj ntawm lub cev muaj zog kuj yog ib qho tseem ceeb ntawm kev ua haujlwm.Txawm hais tias qhov ceev (revolutions) thiab torque txaus, nws yog pointless yog tias nws tsis tuaj yeem ntsia tau rau ntawm cov khoom kawg.

Yog tias koj tsuas yog xav kom ceev ceev, koj tuaj yeem txo tus lej ntawm cov xov hlau, txawm tias tus lej hloov me me, tab sis tshwj tsis yog muaj qhov tsawg kawg nkaus torque, nws yuav tsis tig.Yog li ntawd, nws yog ib qho tsim nyog yuav tau nrhiav txoj hauv kev los ua kom lub zog torque.

Ntxiv nrog rau kev siv cov hlau nplaum uas muaj zog saum toj no, nws tseem ceeb heev kom ua rau lub luag haujlwm ntawm lub voj voog ntawm lub winding.Peb tau tham txog kev txo cov xov hlau winding kom ntseeg tau tias muaj pes tsawg tus kiv puag ncig, tab sis qhov no tsis tau txhais hais tias cov hlau yog xoob xoob.

Los ntawm kev siv cov xov hlau tuab es tsis txhob txo tus naj npawb ntawm windings, qhov loj ntawm cov tam sim no tuaj yeem ntws thiab siab torque tuaj yeem tau txais txawm tias tib qhov ceev.Lub spatial coefficient yog qhov qhia tau tias lub xov hlau raug mob npaum li cas.Txawm hais tias nws yog nce tus naj npawb ntawm nyias lem los yog txo cov tuab tuab, nws yog ib qho tseem ceeb kom tau txais torque.

Feem ntau, cov zis ntawm lub cev muaj zog nyob ntawm ob yam: hlau (hlau) thiab tooj liab (winding).
