Linear Induction Motor

Linear Induction Motor ndi mtundu wa injini yomwe imasintha mwachindunji mphamvu yamagetsi kukhala mphamvu yamakina oyenda, popanda kufunikira kwa zida zotumizira makina monga magiya ndi malamba omwe amafunikira m'ma motor ozungulira achikhalidwe. Mfundo yake yogwirira ntchito imakhazikitsidwa ndi ma elekitiromagineti induction, yomwe imagwirizana kwambiri ndi ma motor rotary induction motors (monga ma asynchronous motors), koma mawonekedwe oyenda amasintha kuchoka ku kasinthasintha kupita ku mzere wowongoka.

Mfundo yogwira ntchito ya Linear Induction Motor ndi mtundu wa injini yomwe imasintha mwachindunji mphamvu yamagetsi kukhala mphamvu yamakina oyenda, popanda kufunikira kwa zida zamakina monga magiya ndi malamba omwe amafunikira pamakina ozungulira achikhalidwe. Mfundo yake yogwirira ntchito imakhazikitsidwa ndi ma elekitiromagineti induction, yomwe imagwirizana kwambiri ndi ma motor rotary induction motors (monga ma asynchronous motors), koma mawonekedwe oyenda amasintha kuchoka ku kasinthasintha kupita ku mzere wowongoka.

Mfundo yake yogwirira ntchito ndi yofanana ndi mota yozungulira yozungulira (motor asynchronous), koma imawululidwa mwanjira yowongoka kuti ikwaniritse njira yowongoka.

Mfundo yaikuluzaLinear Induction Motor

Mfundo yogwirira ntchito ya injini yolumikizira mzere imatha kufananizidwa ndi "motor induction induction motor":

1) .Mumagalimoto amtundu wa rotary induction motors, maginito ozungulira omwe amapangidwa ndi stator amayendetsa rotor (squirrel khola, etc.) kuti azizungulira;

2) .Linear induction motor imavumbulutsa stator kukhala gawo loyamba, ndikupanga maginito oyendayenda omwe amayenda molunjika; Rotor imagwirizana ndi Sekondale, yomwe imapangitsa kuti pakhale mphamvu ya maginito yomwe imagwira ntchito ndi mphamvu yamagetsi (Ampere force), imayenda molunjika motsatira njira ya maginito.

3) .Chachikulu chimadyetsedwa ndi ma alternating current kuti chipangitse mphamvu ya maginito yosuntha, pamene yachiwiri imapangitsa kuti mafunde a eddy apite ku magnetic field. Kulumikizana pakati pa mafunde a eddy ndi mphamvu ya maginito kumapanga mphamvu yoyendetsa, yomwe imayendetsa yachiwiri kuyenda molunjika.

Mapangidwe oyambirazaLinear Induction Motor

Kapangidwe ka liniya induction motor itha kugawidwa m'magawo awiri:

Mwachidule, ma motor induction motors, omwe ali ndi ubwino wake woyendetsa molunjika komanso mawonekedwe osinthika, pang'onopang'ono alowa m'malo mwa njira zotumizira zamakina pamachitidwe omwe amafunikira kusuntha kwa mzere, kukhala gawo lofunikira pakuphatikiza kwamakono kwa mechatronics.

Apa, tikuyambitsa Linear motor, Model TML135-CR ya chilengedwe choyera, yokhala ndi pepala motere:

Linear induction motor imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga mayendedwe, makina opangira mafakitale, ndi zomangamanga chifukwa cha mawonekedwe ake osavuta, otsika mtengo, komanso oyenerera kuyenda kwautali. Nawa mawu oyamba achindunji:

Pankhani ya mayendedwe, masitima apamtunda a maglev ndi amodzi mwa njira zomwe zimagwiritsidwa ntchito paukadaulo wamakina oyendetsa magalimoto. Poika linear motor rotor m'munsi mwa sitimayo komanso stator panjanjiyo, sitimayi imatha kuyimitsidwa ndikuyenda molunjika m'njanjiyo pogwira ntchito yamphamvu ya maginito, kuti ifike{1}}liwiro, -phokoso lochepa,{3}}pogwira ntchito yamphamvu{3}. Kuphatikiza apo, ma linear induction motors atha kugwiritsidwanso ntchito pamakina owongolera okha pamaulendo apanjanji akutawuni, kupereka yankho logwira mtima komanso losinthika pamaulendo akumatauni.

M'malo opangira ma automation a mafakitale, makina opangira ma linear induction motor atha kugwiritsidwa ntchito potumiza zinthu pamizere yopangira makina, kukwaniritsa kuwongolera zinthu mwachangu komanso molondola, kukonza magwiridwe antchito komanso mtundu wazinthu. Nthawi yomweyo, atha kugwiritsidwanso ntchito poyendetsa maloboti, ngati chida cholumikizira maloboti, kuti azitha kuyendetsa bwino kwambiri-zowongolera bwino komanso zosunthika kwambiri, kukonza magwiridwe antchito komanso kusinthasintha kwa maloboti.

Pankhani ya zomangamanga, makina opangira ma linear amatha kugwiritsidwa ntchito kuyendetsa ma elevator. Elevator yakale kwambiri padziko lonse lapansi yogwiritsira ntchito linear motor drive inali ija yoikidwa mu Wanshi Building ku Guam, Tokyo, Japan mu April 1990. Chifukwa cha kusowa kwa mayunitsi okokera m’zikepe zoyendetsedwa ndi ma injini a mzere, chipinda cha makina chomwe chili pamwamba pa nyumbayo chikhoza kuchotsedwa. Kwa nyumba zokhala ndi utali wokwera, chikepe cha waya chaulere choyendetsedwa ndi liniya induction motor ndiye chisankho chabwinoko.

Pankhani ya mayendedwe ndi kusungirako katundu, injini ya linear induction motor ingagwiritsidwe ntchito kukweza mashelefu ndi kunyamula katundu m'malo osungiramo zinthu zitatu-zowoneka bwino kwambiri, kusungirako mwachangu komanso molondola komanso kulanda katundu. M'makina osankha katundu, malamba oyendetsedwa ndi ma linear induction motors amatha kukhala okwera-kuthamanga komanso kusanja kolondola kwa katundu, kuwongolera magwiridwe antchito. Kuphatikiza apo, ma linear induction motors amathanso kugwiritsidwa ntchito pazida monga maloboti opangira zinthu komanso magalimoto owongolera okha.

M'munda wamlengalenga, ma injini opangira ma linear induction motors atha kugwiritsidwa ntchito ngati ma electromagnetic catapult system pa zonyamulira ndege. The electromagnetic ndege ejection dongosolo anayesedwa ndi US Navy, ndi mtima wake kukhala 103 mamita yaitali liniya cholumikizira galimoto, akhoza imathandizira kulemera kwa ndege pafupifupi 4.5-45 matani ndi eject pa liwiro pakati pa 100-370 makilomita pa ola, ndi kusinthasintha ulamuliro tilinazo kuti catapults nthunzi sangathe kukwaniritsa.

Zachipatala: Pazida zojambulira zachipatala, linear induction motor ingagwiritsidwe ntchito kuyendetsa bwino kayendedwe ka zozindikira, ndikumajambula bwino kwambiri-. Mwachitsanzo, mu CT scanner, ma linear induction motors amatha kuyendetsa tebulo kuti liziyenda bwino ndikupeza-zithunzi zamtundu wapamwamba.zofanana ndi mota ya rotary induction motor (asynchronous motor), koma imafutukulidwa mumzere wowongoka kuti ikwaniritse njira yowongoka.
