Drive inta jeer: description iyo dib u eegis

Xeerarkii drive inta jeer ee u ogolaanaya isticmaalaya Converter gaar ah si furfurmi beddelo hababka qalliinka ee motor ah: dhigi billaabin, joojin, dardargelinta, Fariin, beddelo xawaaraha wareeg.

Beddelidda inta jeer ee danab sahayda keenaysaa in isbeddel ku xawaare ku angular duurka magnetic of stator ah. Marka inta jeer ee hoos, xawaaraha engine hoos u, iyo warqada uu kordho.

Mabda'a hawlgalka of drive inta jeer Converter ah

khasaare ugu muhiimsan waa kakanaanta of matoorrada asynchronous xeerka xawaaraha hababka caadiga ah: beddelo danab sahayda iyo hordhaca ah ee windings dheeraad ah resistances Bannaanka. More casri ah waa inta jeer ee drive ee motor ah. Ilaa dhawaan, converters ay SLT, laakiin muuqaalka kore ee IGBT-transistors iyo Hab kontaroolo microprocessor ayaa loo ogol yahay saarayaasha shisheeye si ay u abuuraan qiime la awoodi karo ee qalabka. The maanta sarreeya ee la heli waa converters inta jeer ma guurto ah.

xawaare The angular of ω stator field magnetic ₀ isbeddel ah ee saamiga ƒ noqnoqoshada ₁ sida caanaha,

ω ₀ = 2π × ƒ ₁ / p,

halkaas oo p - tirada laba laba tiir.

Habka uu ogol yahay gacanta ku macaan yahay xawaaraha. At xawaaraha this warqada motor la sii kordhisay.

Si aad u hesho waxqabadka sare awoodda engine ku - oolnimada, factor xoog iyo waqti awood dollar, oo ay la socdaan inta jeer ee la beddelo go'aan ku tiirsanaanta danab:

• Xuddunta load joogto ah - U ₁ / ƒ ₁ = const;
• Fan load qof Xuddunta - U ₁ / ƒ _{February ¹} = const;
• Xuddunta load waa dhigmayn in xawaaraha - U ₁ / √ ƒ ₁ = const.

hawlahaas la fuliyo via transducer halka beddelo inta jeer iyo danab si stator motor ah. Dhawrida xoog by gacanta ku via soo koobin habka loo baahan yahay: bamka cadaadis, awoodda taageere, heerka feed of mishiinka ah, iwm oo xuduudaheedu The habsami kala duwan ..

Hababka for gacanta ku noqnoqoshada induction iyo synchronous matoorrada ah

drives The inta jeer ee ay gacanta ku saleysan matoorrada Dabagaale-qafis asynchronous jira laba siyaabood oo si aad u dalbato maamulka - scalar iyo dulinka. Xaaladda hore, isku mar la beddelo Ilodanimada inayan iyo inta jeer ee danab sahayda.

Tani waa lagama maarmaan si ay u ilaaliyaan waxqabadka engine, ugu of dhan - ratio joogta ah ay Xuddunta ugu badnaan in Xuddunta ah resistive. Sidaas darteed sii hufnaan isku mid ah iyo factor awoodda kala duwan ee wareeg oo dhan.

control dulinka waa isbedel isku mar ee Ilodanimada inayan iyo wajiga ah ee hadda ku stator ah.
