Kusiyana pakati pa Armature ndi Commutator

2022-05-26

Kuphatikizika kwa commutator, mayendedwe a mpira, mapindikidwe & maburashi amatchedwa armature. Ndi gawo lofunikira pomwe magawo onsewa akuphatikiza apa kuti agwire ntchito zosiyanasiyana. Ili ndi udindo pakupanga kusinthasintha kamodzi komwe kumapezeka pakalipano panthawi yonseyi kumalumikizidwa kudzera mumayendedwe am'munda.

Mgwirizano wa flux uwu umapanga zomwe zimapangitsa kuti pakhale chikoka pakuyenda komwe kumachitika. Kuthamanga komwe kumapezeka kumachepetsedwa kapena kupotozedwa chifukwa cha zomwe zidachitika. Komabe, gawo la commutator ndi losiyana ndi zida zankhondo chifukwa limagwiritsidwa ntchito kupanga mphamvu zopanda malire.

Kodi Armature ndi chiyani?
M'makina amagetsi monga ma mota ndi ma jenereta, zida ndi gawo lofunikira lomwe limagwira AC kapena ma alternating current. Mu makina, ndi gawo loyima kapena gawo lozungulira. Kulumikizana kwa armature kudzera mu maginito flux kumatha kupezeka mkati mwa kusiyana kwa mpweya.
Monga kondakitala, chida chimagwira ntchito & nthawi zambiri chimatsetsereka mkati mwa mbali zonse zamunda & komwe kumayendera, kusuntha, kapena mphamvu. Zofunikira za armature makamaka zimaphatikizapo pachimake, shaft, commutator, ndi mapindikidwe.

Zida za Armature. Chombochi chikhoza kupangidwa ndi zigawo zingapo monga pachimake, mapiringidzo, commutator, & shaft.

Chombocho chimagwiritsidwa ntchito pazinthu zosiyanasiyana. Ntchito yayikulu ya izi ndikufalitsa zomwe zikuchitika m'mundamo & kupanga torque ya shaft mumakina omwe akugwira ntchito kapena makina amzere. Ntchito yachiwiri ya izi ndi kupanga mphamvu ya electromotive (EMF).

Mwa izi, kusuntha kwapang'onopang'ono kwa zida ndi gawolo kumatha kukhala mphamvu yamagetsi. Makinawo akagwiritsidwa ntchito ngati mota, ndiye kuti EMF imatsutsana ndi zida zankhondo & imatembenuza mphamvu kuchokera kumagetsi kupita kumakina mu mawonekedwe a torque. Pomaliza, imafalikira pamtunda wonse.

Makinawo akagwiritsidwa ntchito ngati jenereta, ndiye kuti EMF ya zidazo imayendetsa zida zankhondo & kuyenda kumasinthidwa kukhala mphamvu yamagetsi. Mu jenereta, mphamvu yopangidwa idzatengedwa kuchokera ku gawo loyima monga stator.

Kodi Commutator ndi chiyani?
Kusintha kwamagetsi kozungulira ngati chosinthira nthawi ndi nthawi kumatembenuza mayendedwe apano pakati pa rotor & dera lakunja. Woyendetsa amaphatikiza magawo amkuwa omwe amakonzedwa pafupifupi mpaka gawo la makina otembenuza apo ayi, rotor & maburashi odzaza ndi masika amatha kumangirizidwa ku chimango chosagwira cha makina a DC. , oyendetsa ntchito amagwiritsidwa ntchito. A commutator amapereka chithandizo chapano ku ma windings a injini. Makokedwe ozungulira okhazikika amatha kupangidwa mwa kugubuduza komwe akulowera komweko mkati mwa makhoma ozungulira theka lililonse.

Woyendetsa mu jenereta amatembenuza mayendedwe apano kudzera munjira iliyonse yomwe imagwira ntchito ngati makina owongolera kuti asinthe ma AC kuchokera pamamphepo a jenereta kupita ku unidirectional DC mkati mwa dera lakunja la katundu.


Kugwiritsa ntchito zida kumaphatikizapo izi.

Zida zomwe zili mkati mwamagetsi zimagwiritsidwa ntchito kupanga mphamvu.
Itha kugwiritsidwa ntchito ngati stator kapena rotor.
M'mapulogalamu amagetsi a DC, amagwiritsidwa ntchito kuyang'anira kayendedwe kamakono



Ntchito za commutator zikuphatikiza izi.

M'makina amagetsi, ndi gawo losuntha ndipo ntchito yayikulu ya izi ndikutembenuza njira yapano pakati pa rotor & dera lakunja.
Malinga ndi makina a DC, ntchito yake idzasinthidwa
Amagwiritsidwa ntchito pamakina osiyanasiyana a AC ndi DC omwe amaphatikiza ma mota ndi ma jenereta
