Nta ntawm lub cev muaj zog me me: Cov lus hauv qab no qhia txog cov yam ntxwv ntawm lub cev muaj zog, txhuam lub cev thiab lub cev tsis muaj zog.
| Stepper lub cev muaj zog | Txhuam lub cev muaj zog | Brushless lub cev muaj zog | |
| Txoj kev tig | Lub voj voog tsav yog siv los txiav txim qhov kev txiav txim ntawm txhua theem (nrog rau ob theem, peb theem thiab tsib theem) ntawm armature winding.
| Lub armature tam sim no yog hloov los ntawm zawv zawg hu rau rectifier mechanism ntawm txhuam thiab commutator. | Brushless yog paub los ntawm kev hloov txhuam thiab commutator nrog sib nqus ncej sensor thiab semiconductor hloov.
|
| tsav Circuit Court | xav tau | tsis xav tau | xav tau |
| lub zog | Lub torque kuj loj.(tshwj xeeb tshaj yog torque ntawm tsawg ceev)
| Qhov pib torque yog loj, thiab lub torque yog proportional rau lub armature tam sim no.(Lub torque kuj loj ntawm nruab nrab mus rau kev kub ceev) | |
| Kev sib hloov ceev | Lub torque kuj loj.(tshwj xeeb tshaj yog torque ntawm tsawg ceev)
| Nws yog proportional rau qhov voltage thov mus rau armature.Qhov ceev txo nrog qhov nce ntawm qhov load torque | |
| Kev kub ceev kev sib hloov | Nws yog proportional rau input mem tes zaus.Tawm ntawm cov kauj ruam hauv cheeb tsam qis qis, Nws yog qhov nyuaj rau tig ntawm kev kub ceev (nws yuav tsum tau qeeb) | Vim qhov kev txwv ntawm lub tshuab rectifier ntawm txhuam thiab commutator, qhov siab tshaj plaws ceev tuaj yeem ncav cuag ntau txhiab rpm. | Txog li txhiab mus rau kaum txhiab rpm
|
| Hloov lub neej | Nws yog txiav txim los ntawm kev coj lub neej.Kaum tawm txhiab teev
| Txwv los ntawm txhuam thiab commutator hnav.Pua pua mus rau txhiab teev
| Nws yog txiav txim los ntawm kev coj lub neej.Kaum txhiab mus rau pua pua txhiab teev
|
| Forward thiab thim rov qab txoj kev | Nws yog ib qho tsim nyog yuav tau hloov cov theem ntawm excitation theem ntawm lub tsav Circuit Court
| Rov qab polarity ntawm tus pin voltage
| Nws yog ib qho tsim nyog yuav tau hloov cov theem ntawm excitation theem ntawm lub tsav Circuit Court
|
| tswj tau | Qhib lub voj tswj ntawm kev sib hloov ceev thiab txoj hauj lwm (tus nqi sib hloov) txiav txim siab los ntawm cov mem tes hais kom ua tau (tab sis muaj teeb meem ntawm kev tawm ntawm kauj ruam) | Kev sib hloov ceev tas li yuav tsum tau tswj kom ceev (tso tawm tswv yim siv ceev sensors).Txij li thaum torque yog proportional rau tam sim no, torque tswj yog ib qho yooj yim | |
| Nws yooj yim npaum li cas kom tau | Yooj yim: muaj ntau ntau yam | Yooj yim: ntau manufacturers thiab ntau yam, ntau txoj kev xaiv
| Kev nyuaj: feem ntau tshwj xeeb motors rau cov kev siv tshwj xeeb |
| Nqe | Yog hais tias tus tsav tsheb Circuit Court suav nrog, tus nqi yog kim.Pheej yig tshaj brushless lub cev muaj zog
| Tus nqi pheej yig, coreless lub cev muaj zog yog me ntsis kim vim nws cov hlau nplaum hloov kho. | Yog hais tias tus tsav tsheb Circuit Court suav nrog, tus nqi yog kim.

Kev sib piv ntawm micro motors: Daim ntawv qhia radar teev cov kev sib piv ntawm ntau yam me me motors.
Ceev torque yam ntxwv ntawm micro stepping lub cev muaj zog: ua hauj lwm ntau yam siv (tsav tam sim no tsav)
● Kev ua haujlwm tsis tu ncua (nyob): khaws li 30% ntawm lub zog torque nyob rau hauv qhov chaw pib ntawm tus kheej thiab tawm ntawm qhov chaw.
● Lub sijhawm ua haujlwm luv luv (lub sijhawm luv luv): khaws lub zog ntawm thaj tsam li 50% ~ 60% hauv thaj chaw pib ntawm tus kheej thiab tawm ntawm cheeb tsam.
● Qhov kub thiab txias: ua tau raws li qib rwb thaiv tsev ntawm lub cev muaj zog raws li cov khoom thauj saum toj no thiab ib puag ncig kev pabcuam
Cov ntsiab lus tseem ceeb:
1) Thaum xaiv lub cev muaj zog xws li txhuam lub cev muaj zog, kauj ruam lub cev muaj zog thiab tsis muaj lub cev muaj zog, cov yam ntxwv, kev ua tau zoo thiab cov yam ntxwv sib piv ntawm cov motors me tuaj yeem siv los ua ib qho kev siv rau kev xaiv lub cev muaj zog.
2) Thaum xaiv cov motors xws li txhuam lub cev muaj zog, kauj ruam lub cev muaj zog thiab tsis txhuam lub cev muaj zog, lub cev muaj zog ntawm tib qeb suav nrog ntau yam tshwj xeeb, yog li kev sib piv cov txiaj ntsig ntawm cov yam ntxwv, kev ua tau zoo thiab cov yam ntxwv ntawm cov motors me tsuas yog siv rau kev siv.
3) Thaum xaiv cov motors xws li txhuam lub cev muaj zog, kauj ruam lub cev muaj zog thiab tsis txhuam lub cev muaj zog, cov ncauj lus kom ntxaws yuav tsum tau lees paub los ntawm cov kev qhia tshwj xeeb ntawm txhua lub cev muaj zog.
