O le a le tulaga galue o le DC afi?

Faʻafefea e le DC afi taʻavale?

O le DC afi o se masini e liua ai le eletise eletise i totonu o le masini malosi i foliga o rotation. O lona gaoioi e gaosia e le faʻamalositino amioga o electromagagism.DC afi i ai o loʻo aʻafia i totonu, o loʻo maua ai le maneta fanua faʻaaogaina e fausia ai gaioiga. Ae o le a le suiga o lenei maneta tulaga pe a fai o le DC o loʻo faʻaaogaina?  

O le electromagnet, o le fasi uʻamea o loʻo afifiina ma se uaea le faʻaaogaina o loʻo faʻaaoga i luga o le vofatia. Afai o le lua maneta maneta ua faʻaopopoina i itu uma e lua o lenei electromagnet, o le faʻatauga ma aulelei ma matagofie faʻamalosi o le a maua ai se toega.  

Then, there are two problems to solve: feeding the current to the rotating electromagnet without the wires getting twisted, and changing the direction of the current at the appropriate time. O nei faʻafitauli uma o loʻo foia e faʻaaoga ai masini e lua: o se vaeluaina-mama-mama, ma se paga o pulumu.

As it can be seen, the commutator has two segments which are connected to each terminal of the electromagnet, besides the two arrows are the brushes which apply electric current to the rotary electromagnet. I mea moniValu afiDC motors e mafai ona maua e tolu slots nai lo le lua ma lua pulumu.

O lenei auala, e pei ona o le electromognet o loʻo suia lona polatitu ua suia ma o le shaft e ono tumau ai le sasa. Tusa lava pe faigofie ma foliga mai o le a aoga tele i nisi mataupu e fai ai nei motome e le aoga ma masini le mafai ona tumau i le va o le proving i le taimi o le malosi lautele. Talu ai o le polarity i le electromagnet ua suia masini, i nisi o le poletisi o le suia vave, e iʻu i le suia o nisi taimi, ma o nisi taimi o le "taofi" i taimi o loʻo tupu ai le taimi nei. Po o le a lava le mea na tupu, o mataupu ia e aumaia i luga o tumutumu ma le le malamalama i masini.

Faʻatupuina i le 2007, Taʻitaʻi Microeperperconocs (Huizhou) Co., Ltd. o se atunuʻu faʻavaomalo tuʻufaʻatasia R & D, gaosiga. E masani ona tatou gaosiaafi mumu, laina afi,Bldc afi, valevale afi, SMD afi, vaalele-ea-faʻataʻitaʻiga afi, faʻauiga afi ma isi, faʻapea foi ma le micro afi i le tele o le fanua.
