Nga ahuatanga me nga tikanga whakamatautau onekeneke DC.
1. i te ngaohiko whakatau, ko te tere tere, ko te iti rawa o te waa, i te mea ka piki te uta, ka heke te tere me te heke, ka nui haere te tere o te waa, tae noa ki te aukati i te motuka, ka 0 te tere o te motuka, ka nui ake te waa.
2. te teitei o te ngaohiko, ka tere ake te tere o te motuka
Nga paerewa tirotiro kaipuke whanui.
Te whakamatautau tere kore-uta: hei tauira, te mana tohu 12V, te tere kore-uta 16000RPM.
Ko te paerewa whakamatautau kore-uta me noho i waenga i te 14400~17600 RPM (10% hapa), mena he kino
Hei tauira: me noho te naianei kore-uta i roto i te 30mA, mena he kino
Tāpirihia te utaina kua tohua, me eke te tere ki runga ake i te tere kua tohua.
Hei tauira: N20 DC nekeneke ki 298:1 pouaka, uta 500g*cm, RPM kia runga ake 11500RPM. Ki te kore, he kino

Tikanga mahi o N20 DC nekeneke.
Ko te kaikawe hiko i roto i te papa autō ka tukuna ki tetahi tohanga i tetahi huarahi.
Te ture ringa maui a Fleming.
Ko te ahunga o te papa autō ko te maihao taupū, ko te ahunga o te au ko te maihao waenga, ko te ahunga o te kaha ko te ahunga o te koromatua.
Te hanganga o roto o te N20 DC motini.
Te tātaritanga o te ahunga e tukuna ai te rotor (coil) ki roto i te motuka DC1.
I runga i te ahunga o te kaha hiko, ka neke te porowhita ki te karaka, ko te ahunga o te hiko hiko e pa ana ki te waea i te taha maui (e anga ana ki runga) me te ahunga o te kaha hiko e pa ana ki tenei waea kei te taha matau (whakaaro ki raro).
Te tātaritanga o te ahunga e tukuna ai te rotor (coil) i roto i te motini2.
I te wa e tika ana te porowhita ki te papa autō, kaore te motuka e whiwhi i te kaha o te papa autō. Heoi, na te koretake, ka neke haere tonu te porowhita he iti te tawhiti. Mo tenei wa, karekau te commutator me nga paraihe i te whakapiri. Ka huri haere tonu te porowhita ki te karaka karaka, ka hono te commutator me nga paraihe.Ma tenei ka huri te ahunga o te ia.
Te tātaritanga o te ahunga e tukuna ai te rotor (coil) i roto i te motini 3.
Na te commutator me nga paraihe, ka huri te ahunga o naianei kia kotahi te haurua o te hurihanga o te motuka. Ma tenei ara, ka huri haere tonu te motini ki te karaka. Na te mea ko te commutator me te paraihe e tika ana mo te neke haere tonu o te motuka, ka kiia te motuka N20 DC: "Brushed motor"
Ko te ahunga o te kaha hiko e pa ana ki te waea kei te taha maui (e anga whakarunga) me te waea kei te taha matau.
Te anga o te kaha hiko (anga ki raro)
Painga o N20 DC nekeneke.
1. He iti
2. tere hurihuri tere
3. waea ngawari, e rua titi, kotahi hono ki te atamira pai, kotahi hono ki te atamira kino, mono me te purei
4. Ko te kaha o te motika he teitei ake i te motika stepper
