Kusanthula Kwakukulu Kwa Phindu Losintha Ma Asynchronous Motors ndi Permanent Magnet Synchronous Motors.
Timayambira pamakhalidwe a maginito okhazikika a synchronous motor, ophatikizidwa ndikugwiritsa ntchito kuti tifotokozere phindu lonse la kulimbikitsa injini yokhazikika ya maginito synchronous.
Synchronous motor yokhudzana ndi mota ya asynchronous, zabwino zamphamvu kwambiri, kuchita bwino kwambiri, magawo a rotor amatha kuyeza, kusiyana kwakukulu kwa mpweya wa stator-rotor, kuwongolera bwino, kukula kochepa, kulemera kopepuka, kapangidwe kosavuta, torque / inertia ratio, etc. ., mu petroleum, makampani opanga mankhwala, nsalu zopepuka, migodi, zida zamakina a CNC, maloboti ndi madera ena zakhala zikugwiritsidwa ntchito kwambiri, komanso kumphamvu kwambiri (kuthamanga kwambiri, torque yayikulu), yogwira ntchito kwambiri komanso Miniaturization.
Maginito okhazikika a synchronous motor amakhala ndi stator ndi rotor. Stator ndi yofanana ndi injini ya asynchronous ndipo imakhala ndi ma windings atatu ndi stator core. Stator ndi yofanana ndi injini ya asynchronous, yomwe ili ndi ma windings atatu ndi stator core. Rotor ili ndi maginito okhazikika (maginito) okhazikika, omwe amatha kukhazikitsa maginito pamalo ozungulira popanda mphamvu zakunja, kupangitsa kuti injiniyo ikhale yosavuta komanso kupulumutsa mphamvu.
Ubwino wodziwika bwino wa maginito okhazikika a synchronous motor
(1) Popeza kuti rotor imapangidwa ndi maginito okhazikika, mphamvu ya maginito yothamanga kwambiri ndipo palibe kusangalatsa komwe kumafunikira, motero kuthetsa kutayika kwachisangalalo. Poyerekeza ndi injini ya asynchronous, imachepetsa chisangalalo cha mafunde a stator mbali ndi kutayika kwa mkuwa ndi chitsulo cha mbali yozungulira, ndipo imachepetsa kwambiri mphamvu yogwira ntchito. Chifukwa cha kulunzanitsa kwa mphamvu ya stator ndi rotor, palibe kutayika kwachitsulo koyambira pakatikati pa rotor, kotero kuti magwiridwe antchito (mogwirizana ndi mphamvu yogwira) ndi mphamvu (mogwirizana ndi mphamvu yogwira) ndizokwera kuposa za injini ya asynchronous. Maginito osatha a ma synchronous motors nthawi zambiri amapangidwa kuti azikhala ndi mphamvu zapamwamba komanso kuchita bwino ngakhale pakugwira ntchito mopepuka.
(2) Maginito osatha a ma synchronous motors ali ndi mawonekedwe olimba amakina komanso kukana mwamphamvu kusokonezeka kwa torque yamoto chifukwa cha kusintha kwa katundu. Pakatikati pa rotor ya maginito okhazikika a synchronous motor imatha kupangidwa kukhala yopanda kanthu kuti muchepetse inertia ya rotor, ndipo nthawi yoyambira ndi yoyimitsa imathamanga kwambiri kuposa ma asynchronous motors. Kuchuluka kwa torque / inertia kumapangitsa maginito okhazikika a ma synchronous motors kukhala oyenera kugwira ntchito poyankha mwachangu kuposa ma asynchronous motors.
(3) Kukula kwa maginito okhazikika a ma synchronous motors kumachepetsedwa kwambiri poyerekeza ndi ma asynchronous motors, ndipo kulemera kwawo kumachepetsedwanso. Kuchulukana kwamphamvu kwa maginito okhazikika a ma synchronous motors okhala ndi kutentha komweko komanso zida zotchinjiriza zimaposa kuwirikiza kawiri kwa ma motors atatu asynchronous motors.
(4) Dongosolo la rotor ndi losavuta kwambiri, losavuta kusamalira, ndikuwongolera kukhazikika kwa ntchito.
(5) Chifukwa cha mphamvu yayikulu yofunikira pakupanga ma motors asynchronous magawo atatu, ndikofunikira kusunga kusiyana kwa mpweya pakati pa stator ndi rotor yaying'ono kwambiri. Panthawi imodzimodziyo, kufanana kwa kusiyana kwa mpweya kulinso kofunika kwambiri pa ntchito yotetezeka komanso phokoso la kugwedezeka kwa injini. Chifukwa chake, ma asynchronous motors ali ndi zofunika kwambiri pa mawonekedwe ndi kulolerana kwa magawo ndi kukhazikika kwa msonkhano, ndipo pali ufulu wocheperako pakusankha chilolezo. Large chimango asynchronous motors nthawi zambiri amagwiritsa ntchito zitsulo zokongoletsedwa ndi mafuta osambira, M'pofunika kuwonjezera mafuta opaka mkati mwa maola ogwirira ntchito. Kutaya kwamafuta kapena kudzaza mwadzidzidzi m'chipinda chamafuta kumatha kufulumizitsa kulephera. Pokonza ma motors atatu asynchronous motors, kusungirako kumatengera gawo lalikulu. Kuonjezera apo, chifukwa cha kukhalapo kwa kupangitsidwa kwamakono mu rotor ya magawo atatu asynchronous motors, nkhani ya kuwonongeka kwa magetsi ya mayendedwe yakhala yodetsa nkhawa kwa ofufuza ambiri m'zaka zaposachedwa.
(6) Permanent maginito synchronous motors alibe mavuto ngati amenewa. Mavuto omwe amabwera chifukwa cha kusiyana kwakukulu kwa mpweya wa maginito osatha a maginito synchronous motors ndi mpweya waung'ono wa ma asynchronous motors omwe ali pamwambawa sakuwonekera pa ma synchronous motors. Nthawi yomweyo, mayendedwe a maginito okhazikika a synchronous motors amagwiritsa ntchito mayendedwe opaka mafuta okhala ndi zokutira fumbi. Ma bearings amasindikizidwa ndi kuchuluka koyenera kwamafuta opaka mafuta apamwamba kwambiri pafakitale, omwe amatha kusamalidwa kwa moyo wonse.
Epilogue
Pakuwona phindu lazachuma, maginito okhazikika a synchronous motors ndioyenera kwambiri poyambira kwambiri komanso zochitika zopepuka. Kulimbikitsa kugwiritsa ntchito maginito okhazikika a ma synchronous motors kuli ndi phindu pazachuma komanso pagulu, ndipo ndikofunikira kwambiri pakusunga mphamvu ndi kuchepetsa utsi. Pankhani yodalirika komanso kukhazikika, maginito okhazikika a synchronous motors alinso ndi zabwino zambiri. Kusankha maginito okhazikika okhazikika a maginito synchronous motors ndi ndalama zanthawi imodzi komanso zopindulitsa zanthawi yayitali.
Pambuyo pazaka 16 zaukadaulo, Anhui Mingteng Permanent-Magnetic Machinery & Electrical Equipment Co., Ltd ali ndi R&D kuthekera kwamitundu yonse yamagetsi okhazikika a maginito, kuphimba mafakitale osiyanasiyana monga chitsulo, simenti, ndi migodi ya malasha, ndipo imatha kukwaniritsa zosowa za zosiyanasiyana ntchito ndi zipangizo. Poyerekeza ndi ma asynchronous motors amtundu womwewo, zogulitsa zamakampani zimakhala ndi magwiridwe antchito apamwamba, magwiridwe antchito achuma ambiri, komanso zotsatira zopulumutsa mphamvu. Tikuyembekezera mabizinesi ochulukirachulukira omwe amagwiritsa ntchito maginito okhazikika amagetsi posachedwa kuti achepetse kugwiritsa ntchito ndikuwonjezera kupanga!
