Cov qauv ntawm DC Tsav

Cov qauv ntawm DC lub cev muaj zog yuav tsum muaj ob ntu: stator thiab rotor. Qhov chaw nres tsheb ntawm DC lub cev muaj zog yog hu ua stator. Lub luag haujlwm tseem ceeb ntawm stator yog tsim kom muaj ib qho chaw sib nqus. Ib feem uas tig thaum lub sijhawm ua haujlwm yog hu ua rotor. Nws lub luag haujlwm tseem ceeb yog tsim hluav taws xob hluav taws xob torque thiab induced electromotive quab yuam. Nws yog lub hub rau lub zog hloov dua siab tshiab ntawm DC lub cev muaj zog, yog li nws feem ntau hu ua armature. Constructor thiab kiv cua, thiab lwm yam.

Stator

(1) Main magnetic ncej

Lub luag haujlwm ntawm tus ncej tseem ceeb yog los tsim kom muaj huab cua sib nqus sib nqus. Lub ntsiab sib nqus ncej yog tsim los ntawm lub ntsiab magnetic ncej hlau core thiab excitation winding. Cov tub ntxhais hlau feem ntau yog ua los ntawm 0.5mm ~ 1.5mm tuab silicon steel phaj xuas nrig ntaus thiab riveting. Nws muab faib ua ob ntu: lub cev ncej thiab ncej khau. Lub sab sauv ntawm excitation winding yog hu ua ncej lub cev, thiab sab qis yog hu ua ncej lub cev. Cov khau ncej yog dav dua li tus ncej lub cev, uas tuaj yeem tsis tsuas yog kho qhov kev faib tawm ntawm cov hlau nplaum hauv qhov sib txawv ntawm cov huab cua, tab sis kuj pab txhawb kev kho ntawm excitation winding. Lub excitation winding yog ua los ntawm insulated tooj liab hlau thiab yog lub tes tsho ntawm lub hauv paus ntawm lub ntsiab sib nqus ncej. Tag nrho lub ntsiab sib nqus ncej yog tsau rau ntawm lub hauv paus nrog screws.

(2) Kev sib hloov ncej

Lub luag haujlwm ntawm tus ncej commutation yog txhawm rau txhim kho kev sib hloov thiab txo qhov kev sib hloov ntawm cov hluav taws xob uas yuav raug tsim los ntawm cov txhuam hniav thiab cov commutator thaum lub cev muaj zog khiav. Nws yog feem ntau ntsia nruab nrab ntawm ob lub ntsiab sib nqus ncej. tsim los ntawm ncej windings. Lub commutating ncej winding yog ua los ntawm insulated hlau thiab yog lub tes tsho ntawm commutating ncej hlau core. Tus naj npawb ntawm commutating ncej yog sib npaug ntawm lub ntsiab sib nqus ncej.

(3) Tshuab puag

Lub tsev ntawm lub cev muaj zog stator hu ua thav duab. Lub hauv paus muaj ob txoj haujlwm:

Ua ntej, nws yog siv los kho lub ntsiab sib nqus ncej, commutation ncej thiab kawg npog, thiab txhawb thiab kho tag nrho lub cev muaj zog;

Qhov thib ob yog hais tias lub hauv paus nws tus kheej kuj yog ib feem ntawm lub magnetic Circuit Court, uas yog ib tug sib nqus txoj kev ntawm lub magnetic ncej, thiab ib feem ntawm lub magnetic flux kis tau los yog hu ua tus quab. Txhawm rau kom ntseeg tau tias lub hauv paus tshuab muaj lub zog muaj zog txaus thiab zoo sib nqus permeability, nws feem ntau yog ua los ntawm steel castings lossis welded steel daim hlau.

(4) Txhuam cov cuab yeej

Txhuam cov cuab yeej siv los qhia lossis rho tawm DC voltage thiab DC tam sim no. Cov khoom siv txhuam hniav muaj cov txhuam hniav, txhuam hniav, txhuam txhuam thiab txhuam txhuam txhuam. Cov txhuam hniav yog muab tso rau hauv tus txhuam hniav thiab nias nrog lub caij nplooj ntoos hlav, kom muaj kev sib cuag zoo ntawm tus txhuam hniav thiab cov commutator. Cov txhuam hniav yog tsau rau ntawm txhuam txhuam, thiab txhuam txhuam yog ntsia rau ntawm lub rooj txhuam txhuam txhuam. yuav tsum tau insulated. Lub rooj zaum txhuam txhuam yog ntsia rau ntawm lub hau kawg lossis lub hau npog sab hauv ntawm cov kabmob, txoj haujlwm ncig tuaj yeem hloov kho, thiab nws raug kho tom qab hloov kho.

Rotor

(1) Armature tub ntxhais

Cov tub ntxhais armature yog qhov tseem ceeb ntawm lub ntsiab sib nqus Circuit Court, thiab kuj yog siv los embed lub armature winding. Feem ntau, cov tub ntxhais hlau armature yog ua los ntawm cov ntawv xuas nrig ua los ntawm 0.5mm tuab silicon steel los xij thiab laminated kom txo tau qhov poob tam sim no thiab hysteresis poob tsim nyob rau hauv armature hlau tub ntxhais thaum lub cev muaj zog khiav. Cov tub ntxhais hlau stacked yog tsau rau ntawm lub rotating ncej los yog rotor bracket. Lub voj voog sab nraud ntawm cov tub ntxhais hlau yog muab nrog ib qho armature, thiab armature winding yog embedded rau hauv lub qhov.

(2) Armature winding

Lub luag haujlwm ntawm armature winding yog los tsim hluav taws xob torque thiab induced electromotive quab yuam, thiab nws yog qhov tseem ceeb ntawm lub zog hloov dua siab tshiab ntawm DC lub cev muaj zog, yog li nws yog hu ua armature. Nws yog tsim los ntawm ntau lub coils (tom qab no hu ua Cheebtsam) txuas nrog raws li qee txoj cai. Cov coils raug mob nrog lub zog muaj zog enameled xov hlau lossis iav-coated ca tooj liab xov hlau. Lub coil sab ntawm txawv coils yog embedded nyob rau hauv lub armature qhov nyob rau hauv ob txheej. Yuav tsum muaj kev rwb thaiv tsev zoo ntawm cov hlau cores thiab nruab nrab ntawm sab sauv thiab sab qis. Txhawm rau tiv thaiv kom tsis txhob muaj lub zog centrifugal los ntawm kev cuam tshuam lub coil ntug tawm ntawm lub qhov, lub qhov yog tsau nrog ib lub qhov wedge. Qhov kev txiav tawm ntawm lub kauj txuas tawm ntawm qhov txuas yog khi nrog lub thermosetting weft-free iav daim kab xev.

(3) Commutator

Nyob rau hauv DC lub cev muaj zog, lub commutator yog nruab nrog txhuam, uas tuaj yeem hloov lub zog DC sab nraud mus rau qhov hloov tam sim no hauv armature coil, kom cov kev taw qhia ntawm electromagnetic torque yog tas li; Nyob rau hauv lub DC generator, lub commutator yog nruab nrog Cov txhuam hniav tuaj yeem hloov pauv cov hluav taws xob hluav taws xob hloov hluav taws xob cuam tshuam rau hauv lub armature coil mus rau qhov ncaj qha tam sim no electromotive quab yuam los ntawm cov txhuam zoo thiab tsis zoo. Lub commutator yog ib lub tog raj kheej tsim los ntawm ntau ntu commutator, thiab cov commutator ntu yog insulated nrog cov nplooj ntawv mica.

(4) Rotary ncej

Lub rotating ncej plays lub luag hauj lwm ntawm kev txhawb kev sib hloov ntawm lub rotor, thiab yuav tsum muaj ib tug tej yam txhua yam muaj zog thiab rigidity, thiab feem ntau yog ua los ntawm cov hlau puag ncig.
