DC hom
Lub ntsiab cai ua haujlwm ntawm DC lub tshuab hluav taws xob yog los hloov cov hluav taws xob hloov hluav taws xob uas tsim los ntawm qhov sib txuas ntawm lub ntsej muag armature rau hauv DC electromotive lub zog thaum nws tau kos los ntawm tus txhuam xaus los ntawm commutator thiab qhov kev txiav txim siab ntawm lub txhuam.
Cov kev taw qhia ntawm kev siv lub zog hluav taws xob tau txiav txim siab raws li txoj cai ntawm txoj cai (txoj kab sib nqus ntawm cov ntsiab lus nkag mus rau lub xib teg ntawm tes, tus ntiv tes xoo taw qhia rau kev taw qhia ntawm kev txav ntawm tus neeg xyuas pib, thiab lwm plaub tus ntiv tes taw qhia rau kev taw qhia ntawm qhov induced electromotive force hauv tus neeg xyuas pib).
txoj haujlwm ua haujlwm
Cov kev taw qhia ntawm tus neeg xyuas pib lub zog yog txiav txim siab los ntawm txoj cai sab laug. Qhov khub ntawm cov xaim hluav taws xob tsim ib pliag uas ua rau ntawm qhov armature. Lub sijhawm no yog hu ua electromagnetic torque hauv kev siv lub tshuab tig hluav taws xob. Cov kev taw qhia ntawm lub ntsej muag lub zog yog counterclockwise hauv kev sim ua kom lub armature tig counterclockwise. Yog tias lub tshuab hluav taws xob muaj zog tuaj yeem tiv dhau lub zog tiv thaiv lub zog ntawm lub armature (xws li lub zog tiv thaiv torque los ntawm kev sib txhuam thiab lwm qhov teeb meem torque), lub armature tuaj yeem tig rau hauv qhov kev taw qhia counterclockwise.
DC lub cev muaj zog yog lub cev muaj zog ua haujlwm ntawm DC lub zog ua haujlwm thiab siv dav hauv cov kab xev, tshuab kaw lus, DVD tshuab, tshuab ntsuas hluav taws xob, tshuab ziab plaub hau, saib hauv hluav taws xob, khoom ua si, thiab lwm yam.

electromagnetic
Electromagnetic DC lub cev muaj li ntawm tus qauv stator, rotor (armature), commutator (feem ntau hu ua commutator), txhuam, casing, bearings, thiab lwm yam.
Tus stator sib nqus ncej (lub ntsiab sib nqus ncej) ntawm hluav taws xob DC lub tshuab hluav taws xob yog tsim los ntawm cov tub ntxhais hlau thiab ib qho kev lom zem tsis zoo. Raws li cov txheej txheem sib txawv (hu ua kev zam nyob hauv tus txheej txheem qub), nws tuaj yeem muab faib ua DC-motors zoo siab, txhawb lub cev muaj zog DC motors, cais-muaj DC lub cev muaj zog thiab qhov sib xyaw ua ke DC motors. Vim tias txoj hauv kev sib txawv, txoj cai ntawm stator sib nqus ncej flux (tsim los ntawm qhov zoo siab lub kauj ntawm stator ncej yog energized) kuj tseem muaj qhov sib txawv.
Cov cua tshuab thiab lub rotor winding ntawm koob-zoo siab DC lub cev muaj zog txuas nrog ua ke los ntawm tus txhuam thiab tus hloov pauv. Cov teb tam sim no yog sib piv rau cov khoom siv tam sim no. Qhov sib nqus flux ntawm tus stator nce nrog qhov nce ntawm qhov chaw tam sim no, thiab lub zog zoo ib yam li hluav taws xob tam sim no. Lub armature tam sim no yog sib npaug rau cov xwm txheej ntawm qhov tam sim no, thiab qhov nrawm nrawm nrawm raws li lub zog lossis tam sim no nce. Qhov pib lub zog tuaj yeem ncav ntau dua 5 npaug ntawm qhov ntsuas lub zog, thiab lub zog luv luv lub zog tuaj yeem ncav ntau dua 4 npaug ntawm qhov ntsuas qhov ntsuas. Kev hloov pauv nrawm yog qhov loj, thiab tsis muaj qhov nrawm nrawm yog siab heev (feem ntau tsis tso cai khiav hauv qab tsis thauj khoom). Kev tswj kom nrawm tuaj yeem ua tiav los ntawm kev siv sab nraud tiv thaiv thiab cov cua sib txuas ua ke (lossis sib luag), lossis los ntawm kev hloov pauv cov kab sib txuas ua ke.


Qhov kev sib tw winding ntawm shunt-zoo siab DC lub cev muaj zog txuas nrog lub rotor winding, qhov tam sim no kev hloov pauv yog qhov sib luag, qhov pib lub zog yog qhov sib npaug ntawm cov armature tam sim no, thiab qhov pib tam sim no yog li 2.5 zaug ntawm qhov ntsuas tam sim no. Qhov ceev tau txo qis me ntsis nrog qhov nce ntawm qhov tam sim no thiab lub zog, thiab lub sijhawm luv-over torque yog 1.5 npaug ntawm qhov ntsuas lub zog. Qhov ntsuas kev hloov ceev tau me me, li ntawm 5% mus rau 15%. Lub nrawm tuaj yeem hloov kho los ntawm kev ua kom tsis muaj zog txuas ntawm lub zog tsis tu ncua ntawm cov hlau nplaum.
Lub caij nplooj zeeg cua ntawm qhov cais cov hluav taws xob DC lub cev muaj zog txuas nrog lub zog ywj siab rau kev xa hluav taws xob, thiab nws qhov tam sim no zoo li qub tas mus li, thiab qhov pib qhov pib sib piv yog qhov sib npaug ntawm lub armature tam sim no.

Ntxiv nrog rau qhov kev sib tw ntawm cov stator ncej ntawm qhov sib koom ua ke zoo siab DC lub cev muaj zog, kuj tseem muaj cov kiv cua uas muaj kev sib txuas ua ke nrog cov rotor windings (cov lej tig tsawg dua). Cov kev taw qhia ntawm cov hluav taws xob sib nqus tsim los ntawm cov kab hluav taws xob yog tib yam li ntawm lub ntsiab cua. Lub zog pib pib yog kwv yees li 4 npaug ntawm qhov ntsuas lub zog, thiab lub sijhawm luv luv lub zog ntau dua yog kwv yees li 3.5 npaug ntawm qhov ntsuas lub zog. Kev hloov pauv nrawm yog 25% ~ 30% (cuam tshuam nrog kev sib tw ua ke). Qhov nrawm tuaj yeem hloov kho los ntawm kev ua kom tsis muaj zog ntawm cov hlau nplaum.
Kev sib hloov ntawm cov neeg sib tw tau ua los ntawm cov khoom siv hlau xws li nyiaj-tooj ​​liab, cadmium-tooj ​​liab, thiab lwm yam, thiab puab nrog cov yas muaj zog. Cov txhuam yog nyob rau hauv kev sib cuag nrog tus neeg hloov pauv kom muab cov khoom siv tam sim no rau lub rotor windings. Electromagnetic DC txhuam txhuam txhuam feem ntau siv txhuam txhuam cov hlau lossis cov txhuam hluav taws xob hluav taws xob. Cov tub ntxhais hlau ntawm lub rotor yog ua los ntawm laminated silicon steel nplooj ntawv, feem ntau 12 qhov qhib, nrog 12 teeb tsa ntawm armature windings tso rau hauv nws, thiab tom qab txhua qhov winding txuas nrog ua ke, tom qab ntawd nws txuas nrog rau 12 daim phiaj sib pauv.

Synchronous lub cev muaj zog yog nquag AC lub cev muaj zog zoo li induction lub cev muaj zog. Tus yam ntxwv yog: thaum lub sijhawm ua haujlwm tsis tu ncua, muaj kev sib txuas tas li ntawm qhov ceev rotor thiab daim phiaj zaus n = ns = 60f / p, thiab ns dhau los ua tus ceev synchronous. Yog tias qhov zaus ntawm daim phiaj hluav taws xob tsis hloov, qhov ceev ntawm lub tshuab hluav taws xob synchronous lub cev tsis tu ncua yog tas mus li tsis hais qhov loj ntawm lub nra. Synchronous lub cev muaj zog tau muab faib ua cov hluav taws xob ua ke thiab lub tshuab hluav taws xob sib xyaw. Cov tshuab AC nyob hauv cov chaw tsim hluav taws xob niaj hnub yog tsuas yog ua kom tau cov cav hluav taws xob zoo ib yam.
txoj haujlwm ua haujlwm
Kev tsim ntawm lub teb chaw sib nqus loj: qhov tsis txaus siab winding yog dhau los nrog DC excitation tam sim no los tsim qhov chaw uas tsis muaj kev sib nqus ntawm cov nplai, uas yog, lub ntsiab qhov chaw sib nqus tau tsim.
Tus neeg nqa khoom nqa tam sim no: Peb-theem sib koom ua ke armature winding ua raws li lub zog winding thiab dhau los ua tus nqa khoom ntawm cov hluav taws xob muaj peev xwm lossis vim tam sim no.
Txiav cov lus tsa suab: Thawj tus neeg tsav tsheb tsav lub rotor kom tig mus (nkag lub zog rau lub tshuab), qhov kev sib nqus ntawm qhov sib nqus ntawm qhov ncov qaumteb qab teb tig nrog lub taub hau thiab txiav ua ntu ntu stator theem windings (sib npaug rau tus neeg xyuas pib winding thim rov qab txiav qhov kev txhawb zog) teb).
Kev hloov pauv ntawm lub peev xwm hluav taws xob: Vim yog qhov kev txiav txim siab txheeb ze ntawm lub tshuab hluav taws xob thiab lub zog sib nqus tseem ceeb, peb-theem sib npaug sib hloov ua hluav taws xob muaj peev xwm uas nws qhov loj thiab kev hloov pauv ib ntus yuav ua rau hauv qhov cua tshuab. Los ntawm cov hlau lead, AC tuaj yeem muab tau.


Kev sib hloov thiab kev sib luag: Vim yog qhov hloov pauv ntawm qhov sib nqus ntawm qhov sib nqus sib nqus, qhov tsis sib xws ntawm cov hluav taws xob muaj peev xwm hloov pauv; vim yog qhov sib npaug ntawm qhov sib nqus ntawm qhov sib tw, peb-theem sib npaug ntawm cov hluav taws xob muaj peev xwm raug lees paub.
