Dab tsi koj yuav tsum tau them sai sai rau thaum yuav ib lub cev muaj zog DC brushless

Brushless DC lub cev muaj zog yog cov khoom siv hluav taws xob hloov hluav taws xob kom paub txog kev sib hloov hluav taws xob, uas yog, siv cov khoom siv hluav taws xob hloov hluav taws xob es tsis txhob siv cov khoom siv sib txuas thiab txhuam. Nws muaj qhov zoo ntawm kev ntseeg siab, tsis muaj commutation sparks, tsis tshua muaj suab nrov, thiab lwm yam. Nws yog dav siv nyob rau hauv high-grade kaw cov rooj zaum, video recorders, electronics instruments thiab automated office equipment.
Brushless DC lub cev muaj zog muaj cov hlau nplaum ruaj khov rotor, ntau tus ncej winding stator, txoj hauj lwm sensor thiab lwm yam. Txoj hauj lwm sensor raws li kev hloov hauv rotor txoj hauj lwm, raws li ib qho kev txiav txim ntawm lub stator winding tam sim no rau kev sib pauv tam sim no (xws li, kuaj lub rotor sib nqus ncej txheeb ze rau txoj hauj lwm ntawm stator winding, thiab nyob rau hauv qhov kev txiav txim ntawm qhov chaw ntawm qhov chaw ntawm cov cim qhia tau tsim los ntawm lub teeb liab hloov hluav taws xob los tswj lub zog hloov hluav taws xob, raws li qee qhov kev sib raug zoo ntawm cov winding tam sim no hloov). Kev ua haujlwm ntawm stator winding.
Qhov twg kuv yuav tsum tau pib nrog thaum yuav lub DC brushless lub cev muaj zog? Dab tsi yuav tsum tau sau tseg? Cov nram qab no Demark lub cev muaj zog yuav muab cov lus qhia rau koj ib los yog ob, nyob rau hauv kev yuav khoom ntawm DC brushless lub cev muaj zog xaiv yuav xav sib piv thiab saib seb nws puas muaj txiaj ntsig.
1. Ua tib zoo saib xyuas qhov voltage ntawm brushless DC lub cev muaj zog
Qhov hluav taws xob yog muab los ntawm hluav taws xob hloov hluav taws xob tswj los ntawm cov zis ntawm qhov chaw sensor. Kev xaiv cov khoom siv brushless DC lub cev muaj zog yuav tsum xub xaiv qhov tseeb voltage, raws li tus neeg siv khoom xav tau los xaiv qhov ntsuas hluav taws xob los xaiv cov tsav hluav taws xob tsis zoo, xyuam xim rau kev siv qhov hluav taws xob hauv qhov tsis muaj hluav taws xob thiab tag nrho cov txheej txheem tsis pub dhau. qhov ntau teev los ntawm tus tsav.
2. Ua tib zoo saib xyuas qhov tam sim no ntawm brushless DC lub cev muaj zog
Cia peb xaiv lub ncov tam sim no ntawm tus tsav, txoj hauv kev xaiv lub ncov tam sim no twb yog qhov ntsuas tam sim no ntawm lub cev muaj zog Ir (A), tom qab ntawd lub ncov tam sim no Ip (A)=2xIr, txwv tsis pub siv tsav Nyob rau hauv tus txheej txheem ntawm cov zis tam sim no tsis muaj ib tug npaum li cas ntawm engineering margins, yog hais tias lub cev muaj zog yog paub tias yog lub rated tso zis zog (los yog lub siab tshaj plaws tso zis hwj chim) Pr (W) thiab tsav voltage Vr (V), ces lub ncov tam sim no Ip (A) Ntau dua los yog sib npaug rau 4xPr/Vr. 4 x Pr/Vr.
3. Ua tib zoo saib xyuas qhov kub thiab txias ntawm lub cev tsis muaj zog DC.
Peb kuj tuaj yeem teeb tsa lub cev muaj zog raws li qhov tsis muaj, tab sis peb yuav tsum tau teeb tsa raws li cov motors sib txawv los teeb tsa qhov tsim nyog tsis tau, tau kawg, qhov kub ntawm kev siv ntau yam peb kuj yuav tsum tau coj mus rau hauv tus account, qhov dav ntawm qhov kub thiab txias. tus nqi siab dua.
4. Ua tib zoo saib xyuas qhov tsis kam ntawm lub cev muaj zog DC brushless
Raws li cov kev xav tau ntawm lub zog rwb thaiv tsev, txhawm rau ua kom lub cev ua haujlwm ntawm lub cev muaj zog, lub cev muaj zog nrog kab hauv av thiab lub cev muaj zog winding kab, nrog rau hauv av winding kab thiab chassis rwb thaiv tsev tsis kam ntawm cov kab yog ntau dua 100 megohm 500VDC, tuaj yeem tiv taus 600VAC. / 50Hz / 1mA / 1 thib ob withstand voltage tsis tawg.
Cov Lus Cim Tshwj Xeeb: Lub braking ntawm DC brushless lub cev muaj zog siv lub voj voog luv luv ntawm lub cev muaj zog kawg, muaj lub zog nres thaum lub cev muaj zog khiav, thiab tsis muaj lub zog nres thaum nws tsis khiav, thiab qhov siab dua qhov kev sib hloov yog, ntau dua lub braking quab yuam. Txij li thaum lub nres tam sim no tsis dhau los ntawm qhov tam sim no sensing resistor, lub nres tam sim no tswj tsis tau. Yog li ntawd, lub braking ceev tsis tuaj yeem tshaj qhov kev ruaj ntseg braking ceev, txwv tsis pub nws yuav kub hnyiab tau lub hwj chim raj, thov siv lub luag haujlwm no nrog ceev faj.
