Q: Puas yog BLDC lub cev muaj zog stepper, AC lub cev muaj zog, lossis qee yam tshwj xeeb?

A: Brushless DC motors tig hauv cov kauj ruam nrawm nrawm, yog li nws tau ntxias kom muab cov khoom sib hloov no mus rau hauv pawg stepper motor. Raws li tau sau tseg ua ntej, qhov sib txawv ntawm qhov sib txawv yog tias BLDCs feem ntau yog tsim los rau kev ua haujlwm siab, thaum cov kauj ruam tau teeb tsa rau qhov tseeb. Yog tias koj xav tau lub cev muaj zog tig ntawm ntau txhiab RPM, BLDC yog qhov kev xaiv tsim nyog piv rau cov kauj ruam. Muab hais tias BLDC motors muab cov ntsiab lus ntawm kev ua haujlwm stepper thiab servo, ib tus tuaj yeem xav txog BLDCs los ua ib qho kev sib txawv kiag li. Nrog rau kev ua tau zoo thiab kev ua tau zoo, kev tawm tswv yim sib xyaw, thiab cov nqi kho mob qis, BLDC motors yog qhov kev xaiv zoo nkauj rau ntau yam kev ua haujlwm automation.

Q: Vim li cas BLDC motors tig?

A: Raws li lawv lub npe implies, brushless DC motors tsis siv txhuam. Nrog txhuam cov motors, cov txhuam hniav xa tawm tam sim no los ntawm commutator mus rau hauv cov coils ntawm lub rotor. Yog li yuav ua li cas lub cev tsis muaj zog hla tam sim no mus rau rotor coils? Nws tsis yog - vim hais tias cov coils tsis nyob ntawm lub rotor. Hloov chaw, lub rotor yog cov hlau nplaum ruaj khov; cov coils tsis tig, tab sis hloov kho nyob rau hauv qhov chaw ntawm stator. Vim tias cov coils tsis txav mus los, tsis tas yuav muaj cov txhuam hniav thiab cov commutator. Nrog BLDC lub cev muaj zog, nws yog cov hlau nplaum ruaj khov uas tig tau; Kev sib hloov yog ua tiav los ntawm kev hloov cov kev taw qhia ntawm cov magnetic teb generated los ntawm ib puag ncig nyob ruaj ruaj coils. Txhawm rau tswj qhov kev sib hloov, koj kho qhov loj thiab kev taw qhia ntawm tam sim no rau hauv cov coils.

Q: Cov ntaub ntawv dab tsi nyob hauv lub cev tsis muaj zog DC?

A: Cov hlau tsim muaj ze li ntawm tag nrho cov khoom uas muaj nyob rau hauv BLDC lub cev muaj zog, qee cov hlau no yog hlau, tooj liab, tin, thiab hlau tab sis kuj tseem muaj lwm yam khoom siv tsis yog hlau xws li silicon.

Q: Dab tsi yog qhov zoo sib xws ntawm BLDC thiab DC motors?

A: Ob hom motors muaj xws li stator nrog cov hlau nplaum ruaj khov lossis electromagnetic coils nyob rau sab nraud thiab lub rotor nrog coil windings uas tuaj yeem siv los ntawm cov hluav taws xob ncaj qha rau sab hauv. Thaum lub cev muaj zog los ntawm qhov ncaj qha tam sim no, ib qho chaw sib nqus yuav raug tsim nyob rau hauv lub stator, xws li attracting los yog repelling cov hlau nplaum nyob rau hauv lub rotor. Qhov no ua rau lub rotor pib spinning. Lub commutator yuav tsum tau ua kom lub rotor tig, vim hais tias lub rotor yuav nres thaum nws nyob rau hauv txoj kab nrog sib nqus rog nyob rau hauv lub stator. Lub commutator tsis tu ncua hloov DC tam sim no los ntawm windings, thiab yog li hloov cov hlau nplaum ib yam nkaus. Txoj kev no, lub rotor tuaj yeem ua kom tig tau ntev npaum li lub cev muaj zog.

Kev siv cov khoom siv NdFeB txhais tau hais tias lub rotor sib dhos tuaj yeem ua me dua thiab muab kev sib npaug zoo rau sab hauv kom muaj kev vibration tsawg.

Q: Vim li cas kuv lub cev tsis muaj zog tsis tig?

A: Lub cev muaj zog brushless yuav tsum tig ywj siab thaum tag nrho cov xov hlau sib cais vim tias tsis muaj qhov ua tiav. Yog tias lub cev muaj zog tiv thaiv koj qhov kev sib hloov tsis hais txog ntawm cov xov hlau sib txuas, nws yuav zoo li tias koj lub cev muaj qhov luv luv.

Q: Vim li cas BLDC lub cev muaj zog muaj peb Hall sensors?

A: Rau BLDC lub cev muaj zog tig, qhov sib nqus ntawm lub stator coil thiab cov hlau nplaum ntawm lub rotor lub hlau nplaum ruaj khov yuav tsum yog qee lub kaum ntse ntse. Lub rotor tus txheej txheem kis tau tus mob yog ib tug txheej txheem nyob rau hauv uas cov kev taw qhia ntawm lub rotor lub magnetic teb hloov. Txhawm rau kom ntseeg tau qee lub kaum sab xis ntawm qhov sib nqus ntawm ob, thaum lub kaum sab xis nce mus txog qee tus nqi, cov kev taw qhia magnetic teb ntawm stator coil yuav tsum hloov. Tom qab ntawd, yuav ua li cas ib tug txiav txim qhov tsim nyog ntawm kev hloov cov kev taw qhia ntawm lub stator magnetic teb? Peb lub Hall sensors tuaj yeem pab tau. Peb lub Hall sensors yog lub luag haujlwm qhia tus tswj xyuas thaum hloov cov kev taw qhia tam sim no.

Q: Vim li cas brushless DC lub cev muaj zog siv nrog ceev reducer?

A: Feem ntau, qhov txo qis ntawm qhov txo qis tuaj yeem qis li 3: 1 lossis me dua, nws kuj tseem yuav loj li 170: 1 lossis loj dua. Piv txwv li, thaum lub ceev ntawm lub brushless lub cev muaj zog yog 1300 rpm, qhov tso zis ceev ntawm reducer yuav siab li 450 rpm los yog ntau dua, los yog tsawg li 7.5 rpm los yog txawm me me. Common brushless DC motors tsis muaj xws li qhov loj ceev ntau. Txawm hais tias lub cev muaj zog sib txawv ntawm ntau theem, ob-theem lub cev muaj zog uas muaj qhov ceev tshaj plaws yog kwv yees li 2800-2900 rpm thiab 12-theem lub cev muaj zog uas muaj qhov qis tshaj yog li ntawm 450-500 rpm. Tab sis yog hais tias tsuas yog kaum xyoo ntawm kev ceev yuav tsum tau, cov brushless DC tsis tuaj yeem ua haujlwm. Cov khoom siv thauj khoom uas xav tau kev ua haujlwm qis qis feem ntau xav tau lub sijhawm loj dua (xws li tus ntaiv zoo, up-coiler). Txawm tias qhov ceev ntawm brushless DC ua tau raws li qhov yuav tsum tau ua, nws lub sijhawm tsis tuaj yeem ntsib.

Q: Yuav ua li cas tswj lub BLDC lub cev muaj zog?

A: Qhov kev sib tw loj tshaj plaws ntawm BLDC lub cev muaj zog tswj tsis yog txoj haujlwm nrhiav pom thiab hloov theem tab sis pib hom. Txij li thaum lub zog hluav taws xob rov qab thiab qhov kev sib hloov ceev ntawm lub cev muaj zog winding muaj kev sib raug zoo, BEMF yuav tsawg dhau kom tau txais kev kuaj pom tseeb thaum lub sijhawm tig qeeb. Li no, thaum lub tshuab hluav taws xob pib los ntawm kev sib hloov ceev ntawm xoom, rov qab electromotive quab yuam txoj kev feem ntau siv tsis tau. Lwm txoj hauv kev yuav tsum tau txais kev pom zoo los ua ntej lub cev muaj zog rau qee qhov ceev, uas tuaj yeem pab BEMF mus txog qib uas xav tau los ntawm kev kuaj pom thiab hloov mus rau sab nraub qaum electromotive quab yuam txoj kev rau BLDC lub cev muaj zog tswj.

Q: Puas yog brushless DC lub cev muaj zog siv los ua lub tshuab hluav taws xob?

A: Cov khoom siv tuaj yeem khiav ntawm qhov ceev thiab lub zog siab, uas tuaj yeem txuag tau qhov ceev reducer los ntawm kev tsav tsheb loj. Ntau tus neeg muaj kev tsis ntseeg txog seb lub tshuab hluav taws xob tsis muaj DC tuaj yeem siv los ua lub tshuab hluav taws xob hauv qee qhov xwm txheej. Ob leeg tuaj yeem hloov tau ib leeg? Cov hlau nplaum ntawm brushless DC lub cev muaj zog yog qhov sib txawv ntawm lub tshuab hluav taws xob, uas tau muab faib ua kev zoo siab thiab nws tus kheej excitation. Muaj ib qho excitation coil los kho qhov loj thiab kev taw qhia ntawm tam sim no. Lub rotating excitation coil muaj nyob rau hauv daim ntawv ntawm cov tam sim no ncaj qha, circulating nyob ib ncig ntawm ib kab tsis kam, thiab reversible tam sim no hloov nws tam sim no kev taw qhia nyob rau hauv tib txoj kev.

Q: Yuav ua li cas tswj BLDC lub cev muaj zog siv PWM?
