Alternator na-abụkarị akụkụ anọ mejupụtara: rotor, stator, rectifier na okpu ngwụcha.
(1) rotor
Ọrụ nke rotor bụ ịmepụta oghere magnetik na-atụgharị.
Rotor nwere ogwe aka, yok, ikuku magnetik, mgbanaka onye na-anakọta na rotor aro.
A na-apịnye okporo osisi rotor abụọ, na nke ọ bụla n'ime okporo osisi abụọ ahụ nwere ogwe ndọta nnụnụ isii. A na-ahazi ikuku ndọta (rotor coil) na yok magnetik n'ime oghere nke ogwe osisi.
Mgbanaka onye na-anakọta ihe nwere mgbanaka ọla kọpa abụọ nke edobere na ibe ya. A na-agbanye mgbanaka onye na-anakọta ihe na rotor shaft ma kpuchie ya na ogwe osisi. Ejikọtara mgbanaka ndị na-anakọta ihe abụọ na nsọtụ abụọ nke ikuku ndọta.
Mgbe a na-agafe mgbanaka ndị na-anakọta ihe abụọ ahụ n'ime ugbu a kpọmkwem (site na ahịhịa), enwere ugbu a site na ikuku magnetik, na-eme ka ikuku magnetik axial na-emepụta, nke mere na otu ogwe aka na-agbanye n'osisi N na nke ọzọ bụ magnetized. ruo n'osisi S, si otú a na-akpụ okporo ụzọ magnetik isii ụzọ abụọ. Ka rotor na-agbagharị, a na-emepụta oghere magnetik na-atụgharị [1].
Ihe ndọta ndọta nke ihe ntụgharị bụ: yoke →N pole → ọdịiche ikuku n'etiti rotor na stator → stator → oghere ikuku n'etiti stator na rotor → S pole → yoke.
(2) The stator
Ọrụ nke stator bụ ịmepụta alternating current.
The stator mejupụtara stator isi na a stator eriri igwe.
The stator isi mejupụtara silicon ígwè Ibé akwụkwọ na grooves na n'ime mgbanaka, na onye nduzi nke stator winding na-agbakwunyere na uzo nke isi.
The stator winding nwere atọ n'usoro, na atọ nkebi winding nakweere kpakpando njikọ ma ọ bụ triangle (elu ike) njikọ, nke nwere ike igba atọ na-adọ alternating ugbu a.
A ga-emerụ ikuku nke akụkụ atọ dị ka ụfọdụ ihe achọrọ iji nweta otu ugboro, nha nha nha nha, ọdịiche nke 120° ike electromotive nkeji atọ.
1. Ebe dị anya n'etiti akụkụ abụọ dị irè nke eriri igwe ọ bụla kwesịrị ịdị nhata na oghere nke ogwe magnetik nwere.
2. Ebe dị anya n'etiti nsọtụ mmalite nke eriri dị n'akụkụ nke ikuku nke ọ bụla kwesịrị ịdị nhata ma ọ bụ ọtụtụ ebe dị anya nke otu ụzọ ndọta nwere.
3. The mmalite nsọtụ nke atọ-adọ winding kwesịrị ikewapụ site 2π + 120o eletriki Angle (ohere nke nwere otu ụzọ magnetik okporo osisi bụ 360o eletriki Angle).
Na anụ ụlọ JF13 usoro alternator, a ụzọ magnetik okporo osisi akaụntụ maka oghere ọnọdụ nke 6 ohere mpere (60o eletriki Angle kwa oghere), a magnetik okporo osisi akaụntụ maka oghere ọnọdụ nke 3 ohere mpere, otú ọnọdụ etiti oge nke abụọ dị irè n'akụkụ nke. Igwe mmiri ọ bụla bụ oghere 3, ebe dị anya n'etiti mmalite mmalite nke akụkụ ọ bụla na-efegharị n'akụkụ eriri igwe 6 oghere, enwere ike kewaa nsọtụ mmalite nke ikuku nke usoro atọ site na oghere 2, oghere 8, oghere 3. 14 oghere, wdg.
(3) Ndozi
Ọrụ nke onye na-emegharị ihe na-agbanwe agbanwe bụ ịgbanwe ihe ngbanwe nke akụkụ atọ nke ikuku stator n'ime ugbu a kpọmkwem. Onye na-emegharị ihe nke 6-tube alternator bụ sekit na-emezigharị akwa mmiri nke nwere akụkụ atọ nke nwere 6 silicon rectifier diodes, na tubes rectifier 6 na-agbanye (ma ọ bụ welded) na efere abụọ.
1. Njirimara nke diodes silicon rectifier automotive
(1) Nnukwu na-arụ ọrụ ugbu a, na-aga n'ihu nkezi 50A ugbu a, 600A dị ugbu a;
(2) High reverse voltaji, laa azụ ikwughachi elu voltaji 270V, tụgharịa na-abụghị ugboro ugboro elu voltaji 300V;
(3) Enwere naanị otu ụzọ. Ufodu ndu ndu diode na-adikwa mma, ufodu ndu diode adighi nma, a na-akpo tube nke nwere ahịrị ndu di nma, nke a na-akpokwa ahihia ndu ojoo na-adighi mma, ya mere diode ndozi nwere diode na a. diode adịghị mma.
(4) Mkpuchi njedebe
A na-ekekarị ihe mkpuchi nke njedebe n'ime akụkụ abụọ (mkpuchi ihu na azụ azụ), nke na-arụ ọrụ nke idozi rotor, stator, rectifier na mgbakọ brush. A na-ejikarị ihe mkpuchi aluminom na-atụba ihe mkpuchi njedebe nke ọma, nke nwere ike igbochi nkwụsị magnet nke ọma ma nwee ezigbo ọkụ ọkụ.
A na-enye ihe mkpuchi azụ azụ na mgbakọ ahịhịa nke mejupụtara ahịhịa, ihe njide na ahịhịa ahịhịa. Ọrụ nke ahịhịa bụ ịmebata ọkụ eletrik site na mgbanaka onye na-anakọta n'ime ikuku ubi.
Njikọ dị n'etiti ikuku magnetik (brọsh abụọ) na generator dị iche iche, nke mere na e kewara generator n'ime ime na nke dị n'èzí.
1. Internal lap iron generator: A generator na magnetik field winding negative brush ozugbo n'apata ígwè (kpọmkwem jikọọ na ụlọ).
2. Igwe ọkụ na-ekpuchi mpụga: Igwe ọkụ na-eme ka brushes abụọ nke ikuku na-efegharị n'ọhịa na-echekwa ụlọ.
A na-ejikọta electrode na-adịghị mma (ahịhịa na-adịghị mma) nke ikuku magnetik nke ụdị ígwè dị n'èzí na-ejikọta ya na onye na-ahụ maka nhazi, mgbe ahụ, a na-ejikọta ígwè ahụ mgbe ọ gafesịrị.
