The uku-lokaci kewaye

Babban halin yanzu tsarin soma yanzu a duniya ne uku-lokaci haihuwarka, wanda da dama abũbuwan amfãni a kan guda-lokaci.

Uku-lokaci yanzu tsarin kira uku-lokaci igiyoyin generated da uku electromotive sojojin da ciwon guda amplitude da mita amma canja game da juna a lokaci da 120⁰ ko a lokacin wani uku lokaci lokaci.

Kowane raba kewaye, irin wannan uku-lokaci tsarin da aka ce za a rage lokaci.

Phase halin yanzu, wanda yana da za'ayi uku-lokaci kewaye za a iya samu ta hanyar hada uku na wannan janareta, bada guda-lokaci alternating halin yanzu, rotors, abin da suke a wani ajali matsayi, an rigidly a haɗe da juna da kuma ba su canja wuri a lokacin juyawa. A wannan janareta stator windings ake fãta shimfiɗaɗɗa daga juna da 120⁰ a na'ura mai juyi gefe. A karkashin irin wannan yanayi, shi ne quite shakka cewa electromotive karfi na biyu janareta zai tsaya a cikin canje-canje a dangane da farko janareta a kan 120⁰, watau matsakaicin darajar da electromotive karfi na wannan shugabanci a karo na biyu janareta zai zo bayan duk da janareta na'ura mai juyi zai kunna 120⁰. A electromotive karfi na uku janareta ma za a jinkirta dangi zuwa na biyu janareta 120⁰.

Amma irin wannan hanya domin samar halin yanzu, wanda su uku-lokaci kewaye ne uneconomical kuma a zahiri rikitarwa. Sauƙin uku stator windings suna da alaka a guda kunshin. Irin wannan janareta da ake kira da janareta lokaci yanzu.

Saboda haka, stator alternator halin yanzu yana da uku windings (kira janareta bulan), a 120⁰ gudun hijira zumunta da juna. A na'ura mai juyi ne wani uku-lokaci yanzu janareta tare da na'ura mai juyi da fasali m single-lokaci AC janareta.

A lokacin da juyawa daga cikin na'ura mai juyi windings a duk an halitta su daidaita a mita da kuma mawadãta daga cikin electromotive karfi, amma suka ba su lokaci guda isa su kalla. Feminism lafazin faransanci matsakaicin electromotive karfi ne generated a lokacin da nassi na cibiyar arewa iyakacin duniya na na'ura mai juyi a farkon Tuddan, shi ne mai sauki ga cewa matsakaicin electromotive karfi na wannan shugabanci a karo na biyu nada zo bayan nuna na na'ura mai juyi a kan 120⁰, da kuma na uku - bayan juya a kan 240⁰ dangi zuwa na farko.

Haɗa zuwa wani waje kewaye kowane lokaci janareta, mu sami uku lokaci yanzu kewaye da ciwon babu juna ba lantarki sadarwa, a cikinsa kowane raba kewaye igiyoyin a wannan da juriya zai zama daidai a mawadãta amma canja a lokaci dangi zuwa juna ma a 120⁰.

Don haɗa da irin wannan janareta zuwa wani waje kewaye, bukatar shida wayoyi. Don rage yawan wayoyi da zuwa waje kewaye, shi wajibi ne to connect da mai karɓar nada da kuma janareta juna ta samar da electrically guda biyu zuwa uku-lokaci tsarin. Wannan dangane za a iya yi a cikin biyu hanyoyi daban-daban: alwatika da wani star.

Dukansu mahadi sa shi yiwuwa a ajiye abu a cikin watsa daga wannan damar daga uku m uku-lokaci janareto.

Uku-lokaci haihuwarka sanya shi yiwuwa a ƙirƙirar sauki da kuma dace domin na'urar ta yi aiki da lantarki motor, da ake kira asynchronous. Ya na'urar dogara ne a kan aikace-aikace na juyawa Magnetic filin. A cikin sauki hali, wani Magnetic filin za a iya samu ta hanyar juyawa da kofaton maganadisu.

Idan filin da aka sanya a cikin wani juyawa rufaffiyar shugaba, lazimta zuwa axis, Magnetic filin a cikin juyawa intersecting gefen kewaye shugaba zai sa wani electromotive karfi a cikinta shigar da cewa ya haifar da wani shigar da yanzu a cikin wannan rufaffiyar madauki. Wannan halin yanzu hulda tare da Magnetic filin na juyawa maganadisu nada za a juya. ya jũya shugabanci na juyawa ne m da yin amfani da hagu mulki.

Uku lokaci Motors an hada da sassa biyu: a juyawa part - na'ura mai juyi da tukwãne - da stator.

The juyawa Magnetic filin da aka generated a cikin engine ne ba ta hanyar inji juyawa daga cikin Magnetic sandunan, kuma a kwarara daga alternating halin yanzu na gyarawa-lokaci stator windings.

Uku-lokaci haihuwarka aka tsara da daya daga cikin mafi girma da lantarki injiniyoyi na XIX da farkon XX karni. - Rasha m MO Dolivo-Dobrovolsky (1862-1919). Wannan tsarin ya bude gagarumin dama ga masana'antu amfani da wutar lantarki. A mafi muhimmanci su ne:

• tanadi a cikin wayoyi line haɗa da tashar ga mabukaci.
• yiwuwar juyawa Magnetic filin amfani a uku-lokaci Motors.
