A na-agbakọta isi ya site na mgbanaka mgbanaka ígwè nwere oghere dị n'ime.A na-emepụta ngwugwu site na efere, a na-enye ihe siri ike na nke siri ike nke ihe owuwu ahụ site na ịgbado ọkụ ma ọ bụ riveting.N'ime isi, a na-eme oghere maka ịtọba windings, na protrusion ọ bụla bụ yok (isi) maka ntụgharị ntụgharị.A na-agbakọta isi ahụ site na efere nwere ọkpụrụkpụ nke 0.8-1 mm, nke ejiri akara pụrụ iche nke ígwè ma ọ bụ ferroalloys nwere ụfọdụ ikike magnetik.Enwere ike ịnwe ntù n'èzí nke stator iji meziwanye ikpo ọkụ ọkụ, yana oghere dị iche iche ma ọ bụ nkwụsịtụ iji dochie na ụlọ generator.
Ndị na-emepụta ihe nke atọ na-eji windings atọ, otu n'otu oge.Onye ọ bụla winding na-mere nke ọla kọpa ikpuchi waya waya nke nnukwu cross-ngalaba (na a dayameta nke 0,9 ka 2 mm ma ọ bụ karịa), nke enịm ke a ụfọdụ iji na grooves nke isi.The windings nwere ọnụ site na nke alternating ugbu a na-ewepụ, na-emekarị ọnụ ọgụgụ nke pin bụ atọ ma ọ bụ anọ, ma e nwere stators na isii ọnụ (nke ọ bụla n'ime atọ windings nwere ya ọnụ maka ime njikọ nke otu ụdị ma ọ bụ ọzọ).
N'ime oghere nke isi enwere ihe mkpuchi nke na-echebe mkpuchi nke waya site na mmebi.Ọzọkwa, n'ụdị ụfọdụ nke stators, insulating wedges nwere ike ịtinye n'ime grooves, nke ọzọ na-eme dị ka ihe ndozi maka winding ntụgharị.Mgbakọ stator nwekwara ike tinye ya na epoxy resins ma ọ bụ varnishes, nke na-eme ka o doo anya n'ihe owuwu ahụ (na-egbochi ngbanwe nke ntụgharị) ma na-emezi ihe mkpuchi ọkụ eletrik ya.
The stator na-rigidly n'ịnyịnya na generator ụlọ, na taa ihe a na-ejikarị emewe bụ nke stator isi na-eme dị ka akụkụ ahụ.A na-emejuputa nke a n'ụzọ dị mfe: a na-ejikọta stator n'etiti mkpuchi abụọ nke ụlọ generator, nke a na-ejikọta ya na studs - "Sanwichi" dị otú ahụ na-enye gị ohere ịmepụta kọmpat na-eme ka ọ dị jụụ na ịdị mfe nke mmezi.Nhazi ahụ na-ewu ewu, nke a na-ejikọta stator na mkpuchi ihu nke generator, na mkpuchi azụ na-ewepụ ma na-enye ohere ịnweta rotor, stator na akụkụ ndị ọzọ.
Ụdị na njirimara nke stators
Ndị na-emepụta ihe na-emepụta ihe dị iche na ọnụ ọgụgụ na ọdịdị nke grooves, atụmatụ nke ịtọba windings na grooves, ihe osise wiring nke windings na àgwà eletriki.
Dị ka ọnụ ọgụgụ nke grooves maka ntụgharị nke windings, stators bụ nke abụọ ụdị:
• Na oghere 18;
• Na oghere 36.
Taa, imewe oghere 36 bụ nke a na-ejikarị eme ihe, ebe ọ na-enye arụmọrụ eletrik ka mma.Generators na stators na 18 grooves taa nwere ike ịhụ na ụfọdụ ụgbọ ala nke mbụ ntọhapụ.
Dị ka ọdịdị nke grooves si dị, stators bụ nke atọ ụdị:
• Na oghere na-emeghe - oghere nke akụkụ akụkụ akụkụ anọ, ha chọrọ nhazi ọzọ nke ntụgharị ikuku;
• Na nkedo nke mechiri emechi (wedge-shaped) - a na-eme ka ọkpụkpụ ahụ dị elu, ya mere a na-edozi ikuku ikuku site na ịtinye wedges mkpuchi ma ọ bụ cambrics (PVC tubes);

Dị ka atụmatụ winding si kwuo, stators nwere ụdị atọ:
• N'iji loop (loop na-ekesa) sekit - a na-etinye waya nke ikuku nke ọ bụla n'ime oghere nke isi ya na loops (na-emekarị otu ntụgharị na ntinye nke okpukpu abụọ, a na-etinye ntụgharị nke abụọ na nke atọ n'ime oghere ndị a. - ya mere, windings na-enweta ngbanwe dị mkpa iji mepụta ihe ọzọ na-agbanwe agbanwe nke atọ;
• Site na sekit gbadoro ụkwụ na ebili mmiri - a na-etinye waya nke ikuku ọ bụla n'ime oghere na ebili mmiri, na-agafe ha site n'otu akụkụ gaa n'akụkụ nke ọzọ, na n'akụkụ nke ọ bụla enwere ntụgharị abụọ nke otu winding na-eduzi n'otu ụzọ;
• Na sekit na-ekesa ebili mmiri - a na-etinyekwa waya na ebili mmiri, ma ntụgharị nke otu winding na grooves na-eduzi n'akụkụ dị iche iche.
Maka ụdị stacking ọ bụla, winding ọ bụla nwere ntụgharị isii ekesara n'elu isi.
N'agbanyeghị usoro nke ịtọ waya, e nwere atụmatụ abụọ maka ijikọ windings:
• "Star" - na nke a, a na-ejikọta windings n'otu n'otu (njedebe nke ikuku atọ niile na-ejikọta na otu (efu), na njedebe mbụ ha bụ n'efu);
• "Triangle" - na nke a, a na-ejikọta windings na usoro (mmalite nke otu ikuku na njedebe nke ọzọ).
Mgbe ị na-ejikọta windings na "kpakpando", a na-ahụ elu dị elu, a na-eji sekit a na-emepụta ihe na-emepụta ihe na-enweghị ike karịa 1000 watts, nke na-arụ ọrụ nke ọma na obere ọsọ.Mgbe ị na-ejikọta windings na "triangle", nke ugbu a na-ebelata (1.7 ugboro n'ihe metụtara "kpakpando"), Otú ọ dị, generators na ndị dị otú ahụ a njikọ atụmatụ na-arụ ọrụ nke ọma na ike dị elu, na onye nduzi nke obere cross-ngalaba nwere ike ịbụ. eji maka windings ha.
Ọtụtụ mgbe, kama "triangle", a na-eji sekit "kpakpando abụọ" na-eme ihe, na nke a, stator ekwesịghị inwe atọ, ma isii windings - atọ windings na-ejikọta ya na "kpakpando", na abụọ "kpakpando" jikọtara. ibu n'otu n'otu.
N'ihe gbasara arụmọrụ, maka stators, ihe kachasị mkpa bụ voltaji a kwadoro, ike na akara ugbu a na windings.Dị ka voltaji nominal, stators (na generators) kewara ụzọ abụọ:
• Na voltaji ikuku nke 14 V - maka ụgbọ ala nwere voltaji netwọk on-board nke 12 V;
• Na voltaji na windings nke 28 V - maka akụrụngwa na-na-board netwọk voltaji nke 24 V.
Onye na-emepụta ọkụ na-emepụta voltaji dị elu, ebe ọ bụ na voltaji na-adaba na-apụta na rectifier na stabilizer, na n'ọnụ ụzọ grid ike na-abanye, a hụlarị voltaji nkịtị nke 12 ma ọ bụ 24 V.
