High Speed AC Motor
AC injinindi chipangizo chomwe chimasintha mphamvu yamagetsi yamagetsi osinthika kukhala mphamvu yamakina.Galimoto ya AC imakhala makamaka ndi ma elekitiroji okhotakhota kapena mafunde omwe amagwiritsidwa ntchito kuti apange mphamvu ya maginito ndi zida zozungulira kapena rotor.Galimotoyo imapangidwa pogwiritsa ntchito chodabwitsa cha kuzungulira koyilo yamphamvu mu mphamvu yamaginito.Pali mitundu iwiri yama motors a AC: ma synchronous AC motors ndi ma induction motors.
Mapiritsi a stator a gawo lachitatu la AC motor kwenikweni ndi makoyilo atatu olekanitsidwa ndi madigiri 120 kuchokera kwa wina ndi mnzake, omwe amalumikizidwa mu makona atatu kapena mawonekedwe a nyenyezi.Pamene magawo atatu amakono agwiritsidwa ntchito, mphamvu ya maginito imapangidwa mu koyilo iliyonse, ndipo magawo atatu a maginito amaphatikizidwa kuti apeze mphamvu yozungulira yozungulira.
AC injiniimakhala ndi stator ndi rotor, ndipo pali mitundu iwiri ya ma AC motors: ma synchronous AC motor ndi induction motor.Mitundu yonse iwiri yama motors imapanga mphamvu yamaginito yozungulira podutsa ma AC apano munjira yolowera stator, koma mafunde a rotor ya ma synchronous AC motor nthawi zambiri amafunika kuperekedwa ndi DC yapano (chisangalalo chapano) ndi exciter, pomwe mafunde a rotor a induction motor samatero. amafunika kudyetsedwa ndi madzi.
Mapiritsi a stator a gawo lachitatu la AC motor kwenikweni ndi ma coko atatu olekanitsidwa ndi madigiri 120 kuchokera kwa wina ndi mnzake ndikulumikizidwa mu makona atatu kapena mawonekedwe a nyenyezi.Pamene mphamvu ya magawo atatu ikugwiritsidwa ntchito, mphamvu ya maginito imapangidwa mu koyilo iliyonse, ndipo minda itatu imaphatikizidwa kuti ipeze malo ozungulira.Pakalipano akamaliza kugwedezeka kumodzi kwathunthu, mphamvu ya maginito yozungulira imazungulira ndendende sabata imodzi, motero, kusintha kwa mphindi imodzi ya mphamvu ya maginito yozungulira N=60f.Equation f ndi kuchuluka kwa magetsi.
Ma motors a AC amatha kugawidwa kukhala ma motors osinthika ndi ma asynchronous motors (kapena ma motors osalumikizana) malinga ndi kuchuluka kwa kasinthasintha.Kuthamanga kwa rotor kwa motor synchronous nthawi zonse kumakhala kofanana ndi kuthamanga kwa maginito ozungulira mosasamala kanthu za katundu, kotero liwiroli limatchedwa liwiro la synchronous, ndipo monga tafotokozera pamwambapa, limatsimikiziridwa ndi kuchuluka kwa magetsi.Kuthamanga kwa injini ya asynchronous sikukhazikika, koma kumadalira kukula kwa katundu ndi mphamvu yamagetsi.Pakati pa magawo atatu asynchronous motors, pali ma motors osakonzanso ndi ma motors okonzanso.Ma motors ambiri asynchronous mukuchita ndi ma induction motors opanda rectifier (koma ofananira ndi magawo atatu asynchronous rectifier motors ali ndi maubwino a liwiro losinthika mumitundu yosiyanasiyana komanso mphamvu yayikulu), ndipo liwiro lake nthawi zonse limakhala locheperako kuposa liwiro lolumikizana. .
Ntchito zazikulu
AC injiniili ndi magwiridwe antchito apamwamba, ndipo mulibe utsi, fumbi ndi fungo, palibe kuipitsa chilengedwe, komanso phokoso lochepa.Chifukwa cha maubwino angapo, amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana monga kupanga mafakitale ndi zaulimi, zoyendera, chitetezo cha dziko, zida zamalonda ndi zapakhomo, zida zamagetsi zamankhwala, ndi zina zambiri.
