Qhov sib txawv ntawm Armature thiab Commutator

Kev sib xyaw ua ke ntawm commutator, pob bearings, winding & txhuam yog hu ua armature. Nws yog ib qho tseem ceeb uas tag nrho cov khoom no suav nrog ntawm no los ua cov haujlwm sib txawv. Nws yog lub luag hauj lwm rau lub flux tiam ib zaug cov khoom tam sim no thoob plaws hauv lub winding yog txuas los ntawm lub teb flux.

Lub koom haum flux no tsim cov tshuaj tiv thaiv uas nrhiav tau qee qhov cuam tshuam ntawm cov flux tshwm sim. Cov flux tau txais yuav raug txo los yog distorted vim yog armature cov tshuaj tiv thaiv. Txawm li cas los xij, lub luag haujlwm commutator yog qhov sib txawv ntawm qhov armature vim nws yog siv rau kev tsim hluav taws xob unidirectional.

Armature yog dab tsi?
Hauv cov tshuab hluav taws xob zoo li lub cev muaj zog thiab lub tshuab hluav taws xob, lub armature yog ib qho tseem ceeb uas tuav AC lossis hloov tam sim no. Nyob rau hauv ib lub tshuab, nws yog ib feem nyob ruaj ruaj los yog rotating ib feem. Kev sib cuam tshuam ntawm armature los ntawm kev sib nqus flux tuaj yeem ua tiav hauv qhov sib txawv ntawm huab cua.
Raws li tus neeg xyuas pib, lub armature ua haujlwm & feem ntau sloping nyob rau hauv ob qho tib si cov lus qhia thiab cov kev taw qhia ntawm torque, txav, los yog quab yuam. Cov khoom tseem ceeb ntawm lub armature feem ntau muaj xws li cov tub ntxhais, ncej, lub commutator, thiab winding.

Armature Cheebtsam. Lub armature tuaj yeem tsim nrog ntau yam khoom xws li cov tub ntxhais, qhov cua, lub commutator, & ncej.

Lub armature yog siv rau ntau lub hom phiaj. Lub luag haujlwm tseem ceeb ntawm qhov no yog xa mus rau tam sim no thoob plaws hauv thaj teb & tsim cov ncej torque hauv lub tshuab ua haujlwm lossis lub tshuab linear. Lub luag haujlwm thib ob ntawm qhov no yog tsim kom muaj lub zog hluav taws xob (EMF).

Hauv qhov no, ob qho tib si kev txheeb ze ntawm armature & lub teb tuaj yeem yog lub zog hluav taws xob. Thaum lub tshuab siv zoo li lub cev muaj zog, ces EMF yuav tawm tsam qhov tam sim no ntawm armature & nws hloov lub zog los ntawm hluav taws xob mus rau txhua yam hauv daim ntawv torque. Thaum kawg, nws kis nws thoob plaws hauv lub ncej.

Thaum lub tshuab siv los ua lub tshuab hluav taws xob, ces EMF ntawm armature yuav tsav tam sim no ntawm armature & cov lus tsa suab hloov mus rau hluav taws xob fais fab. Hauv lub tshuab hluav taws xob, lub zog tsim hluav taws xob yuav raug rub los ntawm qhov chaw nres tsheb zoo li stator.

Commutator yog dab tsi?
Lub rotating hluav taws xob hloov zoo li lub commutator ib ntus overturned cov ntws ntawm tam sim no ntawm lub rotor & sab nrauv Circuit Court. Lub commutator suav nrog cov txheej tooj liab uas tau teeb tsa kwv yees li ntawm ib feem ntawm lub tshuab tig lwm yam tsis yog lub rotor & ib txheej txhuam ntawm lub caij nplooj ntoos hlav tuaj yeem txuas rau lub cev tsis muaj zog ntawm lub tshuab DC.In DC cov cav tov xws li DC motors thiab generators. , commutators yog siv. Lub commutator muab cov khoom siv tam sim no rau lub cev muaj zog windings. Lub zog rotary ruaj khov tuaj yeem tsim los ntawm kev hloov pauv cov kev taw qhia ntawm tam sim no nyob rau hauv lub teb windings txhua ib nrab tig.

Lub commutator nyob rau hauv lub tshuab hluav taws xob yuav thim rov qab qhov ntws ntawm cov kev taw qhia tam sim no los ntawm txhua qhov tig los ua ib lub tshuab rectifier hloov AC los ntawm lub tshuab hluav taws xob windings mus rau unidirectional DC nyob rau sab nrauv load Circuit Court.

Cov kev siv ntawm armature muaj xws li hauv qab no.

Lub armature nyob rau hauv ib qho hluav taws xob system yog siv los tsim lub zog.
Nws tuaj yeem siv tau zoo li stator lossis rotor.
Hauv daim ntawv thov DC lub cev muaj zog, nws yog siv los saib xyuas qhov ntws ntawm tam sim no



Cov kev siv ntawm commutator muaj xws li hauv qab no.

Hauv cov tshuab hluav taws xob, nws yog qhov txav mus los thiab lub luag haujlwm tseem ceeb ntawm qhov no yog thim rov qab cov kev taw qhia ntawm tam sim no nyob nruab nrab ntawm lub rotor & sab nrauv Circuit Court.
Raws li lub tshuab DC, nws txoj haujlwm yuav raug hloov
It is used in different AC and DC machines which include motors and generators
