Dera atatu gawo

Waukulu dongosolo anatengera tsopano konsekonse ndi atatu gawo madera, omwe ndi zinthu zambiri pa umodzi-gawo.

Zitatu gawo dongosolo otchedwa atatu gawo mafunde kwaiye magulu atatu electromotive ndi matalikidwe chomwecho ndi pafupipafupi koma ankatembenukira ndi ulemu kwa wina ndi mnzake mu gawo ndi 120⁰ kapena pa nthawi kachitatu.

Dera lililonse palokha, chotero dongosolo atatu gawo Akuti kuchepetsa gawo.

Gawo panopa, yomwe ikuchitika atatu gawo dera akhoza zopezera ndi kaphatikizidwe atatu a jenereta chomwecho, kupereka lokhala ndi gawo alternating panopa, rotors, amene ali mu malo amodzi ndi sankalimbana nafe Ufumuyo mzake ndipo sasintha malo awo pa kasinthasintha. Mu jenereta ili windings stator ali zinachitika Chrixitu ndi 120⁰ pa mbali ozungulira. Izi zikachitika, n'zoonekeratu kwambiri kuti mphamvu electromotive a jenereta yachiwiri yaitali kusintha awo, poyerekezera ndi jenereta loyamba 120⁰, mwachitsanzo mtengo pazipita mphamvu electromotive a mbali imodzi mu jenereta wachiwiri kudza pambuyo onse jenereta ozungulira adzatembenukira 120⁰. Mphamvu electromotive a jenereta lachitatu adzamva anachedwa wachibale jenereta chachiwiri 120⁰.

Koma njira ngati yopangira panopa, ndiwo atatu gawo dera, si chuma yotheka ndi mwaukadaulo yovuta. Zimakhala zosavuta kuti atatu stator windings ogwirizana mu phukusi limodzi. Chotero jenereta ndi amatchedwa jenereta gawo panopa.

Choncho, stator alternator panopa ali windings atatu (otchedwa jenereta magawo), pa 120⁰ osamukira wachibale wina ndi mzake. The ozungulira ndi atatu gawo panopa jenereta ndi ozungulira amapanga zofanana osakwatiwa-gawo AC jenereta.

Pa kasinthasintha wa windings ozungulira onse analengedwa ofanana pafupipafupi ndi matalikidwe a mphamvu electromotive, koma sikuti imodzi kufika pazipita awo. Kungoganiza kuti pazipita electromotive mphamvu kwaiye pa nthawi ya ndime ya mzinda wa kumpoto kwa ozungulira pa chiyambi cha kumulowetsa, n'zosavuta kuona kuti pazipita electromotive mphamvu ya mbali imodzi mu koyilo yachiwiri itatha kasinthasintha wa ozungulira pa 120⁰, ndi wachitatu - pambuyo ponditembenukira pa 240⁰ wachibale woyamba.

Kulumikiza ku dera kunja lililonse jenereta gawo timapeza gawo atatu panopa dera opanda cholukanalukana palibe kugwirizana magetsi, mmene aliyense osiyana dera mafunde pa yomweyo kukana awo adzakhala ofanana matalikidwe koma ankatembenukira mu gawo wachibale wina ndi mnzake ku 120⁰.

Kulumikiza jenereta ngati kuti ndi dera kunja, muyenera mawaya asanu. Kuchepetsa chiwerengero cha mawaya amene amapita ku dera kunja, m'pofunika kugwirizana wolandila koyilo ndi jenereta cholukanalukana mawonekedwe electrically zolumukizidwa dongosolo atatu gawo. kugwirizana izi zikhoza kutheka m'njira ziwiri zosiyana: kansalu ndi nyenyezi.

Onse mankhwala n'zotheka kuti apulumutse nkhani za kufala kwa mphamvu yomweyo zitatu palokha magudumu atatu gawo.

Zitatu gawo madera kunapangitsa kuti kulenga losavuta ndi yabwino chipangizo ntchito injini ya magetsi, wotchedwa asynchronous. chipangizo potengera mmene tingagwiritsire ntchito onsewo maginito. Pankhani losavuta, ndi maginito akhoza akamagwira onsewo ndi horseshoe maginito.

Ngati munda aikidwa mu onsewo chatsekedwa wochititsa, yomatidwa olamulira, ndi maginito mu kasinthasintha ake intersecting mbali dera akuchititsa kupangira mphamvu electromotive m'menemo kupatsidwa ulemu kuti amapanga ndi panopa kupatsidwa ulemu mu khwekhweli chatsekedwa. Izi zimavuta panopa ndi maginito ya onsewo maginito koyilo adzakhala atembenuza. akutembenukira malangizo a kasinthasintha anatsimikiza pogwiritsa ntchito wamanzere ulamuliro.

Atatu gawo Motors ndi zigawo ziwiri: a onsewo mbali - ndi ozungulira ndi n'kupuma - ndi stator.

The onsewo maginito ndi kwaiye mu injini si ndi makina kasinthasintha zake maginito, ndi pa otaya alternating panopa atathana-gawo stator windings.

madera atatu gawo tinalengedwa ndi mmodzi mwa akatswiri wamkulu amagetsi a XIX ndi oyambirira XX atumwi. - Russian injiniya MO Dolivo-Dobrovolsky (1862-1919). dongosolo watsegula mwayi waukulu ntchito mafakitale magetsi. Chofunika kwambiri ndi:

• ndalama mu Kulumikizana mzere kulumikiza siteshoni kwa ogula;
• kuthekera kwa onsewo maginito ntchito Motors atatu gawo.
