Thaum tsim cov khoom siv siv cov cav, nws yog ib qho tsim nyog los xaiv lub cav uas haum tshaj plaws rau txoj haujlwm xav tau. Daim ntawv no yuav piv cov yam ntxwv, kev ua tau zoo thiab cov yam ntxwv ntawm lub cav txhuam,lub cev muaj zog stepperthiab lub cev muaj zog brushless, vam tias yuav yog ib qho kev siv rau txhua tus neeg thaum xaiv cov motors. Txawm li cas los xij, vim tias muaj ntau yam kev qhia tshwj xeeb hauv tib pawg ntawm cov motors, thov siv lawv rau kev siv xwb. Thaum kawg, nws yog qhov tsim nyog los paub meej cov ntaub ntawv ntxaws ntxaws los ntawm cov lus qhia tshwj xeeb ntawm txhua lub cev muaj zog.
Cov yam ntxwv ntawm lub cev muaj zog me me: Cov lus hauv qab no piav qhia txog cov yam ntxwv ntawm lub cev muaj zog kauj ruam, lub cev muaj zog txhuam thiab lub cev muaj zog txhuam.
| Lub cev muaj zog stepper | Lub cev muaj zog txhuam | Lub cev muaj zog tsis txhuam | |
| Txoj kev tig | Lub voj voog tsav tsheb siv los txiav txim siab qhov kev txiav txim ntawm txhua theem (suav nrog ob theem, peb theem thiab tsib theem) ntawm lub armature winding. | Lub armature tam sim no yog hloov los ntawm lub sliding contact rectifier mechanism ntawm txhuam thiab commutator. | Brushless yog ua tiav los ntawm kev hloov txhuam thiab commutator nrog magnetic pole position sensor thiab semiconductor switch. |
| lub voj voog tsav tsheb | xav tau | tsis xav tau | xav tau |
| lub zog tig | Lub torque loj heev. (tshwj xeeb tshaj yog torque ntawm qhov ceev qis) | Lub zog pib loj, thiab lub zog torque yog proportional rau lub zog tam sim no. (Lub zog torque yog qhov loj ntawm qhov nruab nrab mus rau qhov ceev siab) | |
| Kev sib hloov ceev | Lub torque loj heev. (tshwj xeeb tshaj yog torque ntawm qhov ceev qis) | Nws yog proportional rau lub voltage siv rau lub armature. Qhov ceev txo qis nrog rau qhov nce ntawm load torque | |
| Kev sib hloov ceev ceev | Nws yog proportional rau lub input pulse zaus. Tawm ntawm kauj ruam cheeb tsam hauv qis ceev ntau yam, Nws yog qhov nyuaj rau tig ntawm kev kub ceev (nws yuav tsum qeeb qeeb) | Vim yog qhov txwv ntawm lub tshuab rectifier ntawm txhuam thiab commutator, qhov ceev siab tshaj plaws tuaj yeem ncav cuag ntau txhiab rpm | Txog li ntau txhiab txog kaum txhiab rpm |
| Lub neej tig mus los | Nws yog txiav txim siab los ntawm kev coj tus kheej lub neej. Kaum tawm txhiab teev | Txwv los ntawm kev siv txhuam thiab commutator. Pua pua txog ntau txhiab teev | Nws yog txiav txim siab los ntawm kev coj lub neej. Kaum tawm txhiab mus rau ntau pua txhiab teev |
| Cov txheej txheem tig mus tom ntej thiab rov qab | Nws yog ib qho tsim nyog los hloov qhov sib lawv liag ntawm cov theem excitation ntawm lub voj voog tsav tsheb | Rov qab lub polarity ntawm lub pin voltage | Nws yog ib qho tsim nyog los hloov qhov sib lawv liag ntawm cov theem excitation ntawm lub voj voog tsav tsheb |
| kev tswj tau | Kev tswj hwm lub voj voog qhib ntawm qhov ceev thiab qhov chaw (qhov ntau ntawm kev sib hloov) txiav txim siab los ntawm lub zog hais kom ua tuaj yeem ua tau (tab sis muaj teeb meem ntawm kev tawm ntawm kauj ruam) | Kev tig ceev tas li xav tau kev tswj ceev (kev tswj cov lus teb siv cov sensors ceev). Vim tias torque yog proportional rau tam sim no, kev tswj torque yog yooj yim | |
| Nws yooj yim npaum li cas kom tau txais | Yooj yim: muaj ntau hom | Yooj yim: ntau lub chaw tsim khoom thiab ntau yam, ntau txoj kev xaiv | Qhov nyuaj: feem ntau yog cov cav tshwj xeeb rau cov ntawv thov tshwj xeeb |
| Nqe | Yog tias lub voj voog tsav tsheb suav nrog, tus nqi kim heev. Pheej yig dua li lub cev muaj zog brushless | Pheej yig dua, lub cev muaj zog tsis muaj zog kim me ntsis vim nws qhov kev hloov kho hlau nplaum. | Yog tias lub voj voog tsav tsheb suav nrog, tus nqi kim heev. |
Kev sib piv ntawm kev ua tau zoocov cav me meDaim ntawv qhia radar teev cov kev sib piv kev ua tau zoo ntawm ntau lub cev muaj zog me me.
Cov yam ntxwv ntawm lub zog ceev ntawm lub cev muaj zog micro stepping: Kev siv ntau yam (kev tsav tsheb tas li)
● Kev ua haujlwm tas mus li (ntsuas): khaws kwv yees li 30% ntawm lub zog torque hauv thaj chaw pib nws tus kheej thiab tawm ntawm thaj chaw kauj ruam.
● Ua haujlwm luv luv (qib luv luv): khaws lub zog torque kom txog li 50% ~ 60% hauv thaj chaw pib thiab tawm ntawm thaj chaw kauj ruam.
● Kub nce: ua tau raws li qhov yuav tsum tau ua ntawm lub cev muaj zog hauv qab qhov ntau thiab tsawg saum toj no thiab qhov chaw ua haujlwm
