Kev txo qis ntawm hydrocarbon fuels, kev puas tsuaj ntawm ib puag ncig thiab lwm yam laj thawj yuav sai lossis tom qab yuam cov tuam txhab tsim cov qauv ntawm cov tsheb fais fab uas yuav dhau los ua rau cov pej xeem. Lub sijhawm no, nws tsuas yog tos lossis tsim cov kev xaiv rau ib puag ncig tus phooj ywg thev naus laus zis nrog koj tus kheej tes.

Yog koj tseem xav nrhiav kev daws koj tus kheej, tsis yog tos lawv los ntawm sab nraud, ces koj yuav tsum paub tias lub tshuab hluav taws xob twg twb tau tsim lawm, lawv txawv li cas thiab qhov twg yog qhov zoo tshaj plaws.

Traction motor

Yog tias koj txiav txim siab tso lub tshuab hluav taws xob zoo tib yam hauv qab lub hood ntawm koj lub tsheb, feem ntau yuav tsis muaj dab tsi los ntawm nws. Thiab tag nrho vim tias koj xav tau lub tshuab hluav taws xob traction (TED). Nws txawv ntawm cov pa hluav taws xob lub cev muaj zog ntau dua, muaj peev xwm xa tau ntau lub zog, qhov me me thiab qhov hnyav tsawg.

rauCov roj teeb yog siv los txhawb lub zog traction motor. Lawv tuaj yeem raug them rov qab los ntawm cov chaw sab nraud ("los ntawm lub qhov (socket)"), los ntawm cov hnub ci vaj huam sib luag, los ntawm lub tshuab hluav taws xob tau teeb tsa hauv lub tsheb, lossis hauv hom rov qab (tus kheej rov qab them nqi).

Lub cev muaj zog rau lub tsheb fais fab feem ntau yog siv los ntawm lithium-ion roj teeb. TED feem ntau ua haujlwm hauv ob hom - lub cev muaj zog thiab lub tshuab hluav taws xob. Nyob rau hauv rooj plaub tom kawg, nws ntxiv cov khoom siv hluav taws xob thaum hloov mus rau nruab nrab ceev.

Txoj Cai Ua Haujlwm

Ib tus qauv hluav taws xob muaj ob lub ntsiab lus - stator thiab rotor. Thawj cov khoom yog nyob ruaj ruaj, muaj ob peb coils, thiab qhov thib ob ua rau kev sib hloov thiab hloov lub zog mus rau lub ncej. Ib qho kev hloov hluav taws xob tam sim no yog siv rau cov stator coils nrog qee lub sijhawm, uas ua rau pom qhov sib nqus, uas pib tig lub rotor.

Qhov ntau zaus cov coils tig rau thiab tawm, qhov nrawm nrawm dua. Ob hom rotor tuaj yeem ntsia tau rau hauv lub cev muaj zog rau lub tsheb fais fab:

• luv-circuited, nyob rau hauv uas ib tug magnetic teb tshwm sim opposite rau stator teb, vim hais tias kev sib hloov tshwm sim;
• phase - siv los txo qhov pib tam sim no thiab tswj qhov nrawm ntawm kev sib hloov ntawm cov ncej, yog qhov feem ntau.

Ntxiv rau, nyob ntawm qhov ceev ntawm kev sib hloov ntawm cov hlau nplaum thiab lub rotor, cov motors tuaj yeem ua asynchronous thiab synchronous. Ib lossis lwm hom yuav tsum raug xaiv los ntawm cov peev txheej thiab cov haujlwm.

Synchronousengine

Lub tshuab synchronous yog TED, nyob rau hauv uas lub rotor kev sib hloov ceev coincides nrog lub magnetic teb kev sib hloov ceev. Nws raug nquahu kom siv cov motors no rau cov tsheb hluav taws xob nkaus xwb thaum muaj qhov muaj zog ntxiv - los ntawm 100 kW.

Ib qho ntawm ntau yam ntawm synchronous electric motors yog lub cev muaj zog stepper. Lub stator winding ntawm xws li ib tug installation yog muab faib ua ob peb seem. Nyob rau hauv ib lub sij hawm, tam sim no yog nkag mus rau ib tug tej seem, ib tug magnetic teb tshwm sim uas tig lub rotor ntawm ib tug tej lub kaum sab xis. Tom qab ntawd qhov tam sim no siv rau ntu txuas ntxiv, thiab cov txheej txheem rov ua dua, cov ncej pib tig.

Asynchronous electric motor

Nyob rau hauv lub asynchronous lub cev muaj zog, qhov ceev ntawm kev sib hloov ntawm lub magnetic teb tsis phim qhov ceev ntawm kev sib hloov ntawm lub rotor. Qhov zoo ntawm cov khoom siv no yog kev ruaj ntseg - cov khoom seem rau cov tsheb fais fab uas muaj cov kev teeb tsa no yooj yim heev los nrhiav. Lwm cov txiaj ntsig suav nrog:

1. Simple design.
2. Kev kho yooj yim thiab ua haujlwm.
3. Tus nqi qis.
4. Kev ntseeg siab.

Txawm li cas los xij, nyob ntawm qhov muaj cov txhuam txhuam-cov khoom siv, cov motors tuaj yeem hloov pauv thiab tsis muaj kev sib hloov. Lub collector yog ib qho khoom siv uas hloov AC rau DC. Cov txhuam hniav yog siv los hloov hluav taws xob rau lub rotor.

Brushless motors rau lub tsheb fais fab yog sib dua, compact thiab ntau dua. Lawv tsis tshua muajoverheat thiab siv hluav taws xob tsawg. Qhov tsuas yog qhov tsis zoo ntawm xws li lub cav yog tus nqi siab ntawm cov khoom siv hluav taws xob, uas ua raws li cov khoom siv. Tsis tas li ntawd, cov khoom seem rau cov tsheb fais fab uas nruab nrog lub cev tsis muaj zog yog qhov nyuaj nrhiav.

Electric Motor Manufacturers

Txhua lub tsheb hluav taws xob hauv tsev yog tsim los siv lub tshuab hluav taws xob sib txuas. Qhov no yog vim muaj, tus nqi qis thiab kev saib xyuas yooj yim.

Lub chaw tsim khoom tseem ceeb ntawm cov motors yog German tuam txhab Perm-Motor. Nws cov khoom muaj peev xwm ntawm regenerative braking nyob rau hauv generator hom. Nws yog nquag siv los nruab scooters, lub nkoj tsav, tsheb, hluav taws xob nqa khoom. Yog tias Perm-Motor xyaw tau teeb tsa hauv txhua lub tsheb hluav taws xob, lawv tus nqi yuav qis dua. Tam sim no lawv raug nqi ntawm 5-7 txhiab euros.

Ib lub chaw tsim khoom nrov yog Etek, uas tau koom nrog hauv kev tsim cov tshuab tsis siv neeg txhuam thiab txhuam commutator. Raws li txoj cai, cov no yog peb-theem motors ua haujlwm ntawm cov hlau nplaum ruaj khov. Cov txiaj ntsig tseem ceeb ntawm kev teeb tsa:

• control raug;
• yooj yim ntawm lub koom haum rov qab;
• kev ntseeg siab vim kev tsim qauv yooj yim.

Cov npe ntawm cov tuam txhab ua tiav los ntawm Advanced DC Motors cog los ntawm Asmeskas, uas tsim cov khoom siv hluav taws xob. Qee cov qauv muaj qhov tshwj xeeb tshwj xeeb - lawv muaj lub ntxaiv thib ob, uas tuaj yeem siv los txuas rau lub tsheb fais fabkhoom siv hluav taws xob ntxiv.

Lub cav xaiv qhov twg

Yog li kev yuav khoom tsis ua rau koj poob siab, koj yuav tsum sib piv cov yam ntxwv ntawm tus qauv yuav khoom nrog cov kev xav tau ntawm lub tsheb. Thaum xaiv lub tshuab hluav taws xob, lawv feem ntau yog coj los ntawm nws hom:

• Synchronous installations yog qhov nyuaj thiab kim, tab sis lawv muaj peev xwm dhau, lawv tswj tau yooj yim dua, lawv tsis ntshai ntawm qhov poob qis, lawv siv cov khoom siv siab. Lawv tau nruab rau ntawm lub tsheb hluav taws xob Mercedes.
• Asynchronous qauv yog tus nqi qis, khoom siv yooj yim. Lawv yooj yim los tswj thiab khiav lag luam, tab sis lawv cov zis hluav taws xob tsawg dua li ntawm cov nroj tsuag synchronous.

Tus nqi ntawm lub tsheb hluav taws xob yuav qis dua yog tias lub tshuab hluav taws xob txuas nrog lub tshuab hluav taws xob sab hauv. Nyob rau hauv kev ua lag luam, xws li cov nroj tsuag ua ke yog nrov dua, txij li lawv cov nqi yog li ntawm 4-4.5 txhiab euros.
