Waa maxay sababta commutator looga shaqeeyaa mishiinnada DC?

A isu gudbiyewaxaa looga shaqeeyaa mishiinnada DC (sida tooska ah ee hadda jira), sida matoorada DC iyo koronto-dhaliyeyaasha DC, dhowr sababood oo muhiim ah dartood:

U Beddelka AC una Beddelka DC: Matoorayaasha DC-ga, commutator-ku waxa uu u adeegaa si uu u beddelo hadda beddelka ah (AC) ee ka dhasha dabaylaha hubka si uu u noqdo wax soo saarka hadda (DC). Sida qalabku u wareego gudaha sagxadda birlabeedka, gawaadhihu waxa uu rogaa jihada hadda ee gariiradda armature kasta wakhtiga ku habboon, isaga oo hubinaya in wax soo saarka hadda jira uu si joogto ah ugu socdo hal jiho.

Dayactirka Jihada Hadda: Matoorada DC-ga, wada-socduhu waxa uu hubinayaa in jihada hadda loo marayo dabaylaha armature-ku ay sii ahaato mid joogto ah marka rotorku uu ku wareego gudaha goobta birlabeedka. Qulqulka aan jiho lahayn ee hadda socda waxa uu soo saara qulqulo joogto ah kaas oo dhaqaajiya wareegga matoorka.

Jiilka Torque-ga: Adigoo mar mar dib u rogaya jihada hadda ee dabaylaha armature-ku, wada-socodku wuxuu abuuraa wareeg joogto ah matoorada DC. Wareeggani waxa uu awood u siinayaa matoorku in uu ka adkaado firfircooni la'aanta iyo culeysyada dibadda, taas oo keenta wareegyo siman oo joogto ah.

Ka-hortagga Suugaan-gaaban: Qaybaha isu-socodka, ee ka go'an midba midka kale, ayaa ka hortagaya wareegyada gaagaaban ee u dhexeeya gariiradaha suubban ee ku xiga. Marka uu wareeguhu wareego, waxa ay hubisaa in gariiradda armature kasta ay ilaaliso xidhiidhka korantada ee wareegga dibadda iyada oo loo marayo burushyada iyada oo laga fogaanayo xidhiidhka gariiradda deriska ah.

Xakamaynta Xawaaraha iyo Torque: Naqshadeynta commutator, oo ay weheliso tirada qaybaha iyo qaabeynta dabaysha, waxay u oggolaaneysaa xakamaynta xawaaraha iyo sifooyinka mashiinnada DC. Arrimo kala duwan sida korantada la dabaqay iyo xoogga goobta magnetic, hawl-wadeenadu waxay hagaajin karaan xawaaraha iyo wax soo saarka matoorka ama koronto-dhaliye si ay ugu habboonaadaan shuruudaha gaarka ah.

Guud ahaan, theisu gudbiyewuxuu door muhiim ah ka ciyaaraa shaqada mashiinada DC isagoo fududeynaya beddelka tamarta korantada ee tamarta farsamada (matoorada) ama lidka ku ah (matoorayaasha) iyadoo la ilaalinayo isku xirka korantada ee la isku halayn karo iyo xakameynta jihada iyo baaxadda socodka hadda.
