Shigar da mota, aiki ka'idojin - ba zai iya zama sauki ...

The kalmar "engine" ko da yaushe ya haifar da wani misali na wani abu mirgina, har ma fiye da akai-akai - juyawa. A fili yake - da kuma saboda engine. Jigon kowane engine - maida wani irin makamashi a motsi. Kada ka san abin da irin engine shi ne na farko? An yi imani da cewa shi ne mai ze tashi. Shi ba zai zama daidai ba ne a ce ya fi kowa engine - lantarki. Daga cikin iri-iri na lantarki inji a cikin wannan aji ne mafi girma aikace-aikace samu asynchronous mota, da manufa na aiki dogara ne a kan yin amfani da muhimman abubuwa biyu bayyananen lantarki da makamashi - wutar lantarki da kuma electromagnetic shigar da.

Don gane da manufa na shigar da mota, tuna da sauki abubuwan da makaranta kimiyyar lissafi shakka:

• idan halin yanzu gudãna ta hanyar da shugaba, shi ya auku a kusa da Magnetic filin gwargwado ga halin yanzu.
• idan ka dauki biyu yanzu-dauke shugaba, tsakanin su akwai wani karfi filin - su tare ko jawo hankalin juna, a daidai wannan hanya kamar yadda shi ne yake aikata dukan guda na maganadiso.
• idan daya halin yanzu-dauke shugaba motsa zumunta zuwa wani, cewa ba a haɗa Madogararsa, amma kewaye da aka rufe, akwai wani halin yanzu a cikinta.

Jiki, ko, mafi daidai, da tabbas, da aiwatar da tsarin hada da manufar Magnetic filin Lines, wanda muka nuna a fakaice gaban Magnetic Properties. Ga su ne, sa'annan su yada "tentacles" a duk inda, kuma idan ka zo a fadin a cikin hanyar wani ferromagnetic abu, watau, waɗanda a cikin abin da Magnetic Lines sun mayar da hankali, shi abubuwa a kan shi da kuma tuki da karfi. Kuma idan abu kanta tana da maganadisu, da karfi hulda da Magnetic filayen da aka fi alama. Kara da Magnetic filin da shugaba za a iya rauni a manyan yawan windings a kan wani core na ferromagnetic abu - a cikin sauki hali, wannan shi ne saba karfe Silinda na ferrous karfe. Quite sauki yin kofaton fil, da kuma sa a kan wani Tuddan shi. A iyakar da "kofaton" zama sandunan da wani maganadisu, wanda shi ne lokacin da na yanzu ta hanyar da nada Halicci karfi iyakar a cibiyar sandunan, Magnetic filin. Yadda aka saba, muna ganin shi a kan wani itace adadi.

Idan da rata tsakanin sanduna sanya wani karfe sanda, sa'an nan za a fara kafin a juya mu Magnetic "kofaton", za mu lura cewa bar ma za a juya su. Me mu na'urar kira wani shigar da mota? Ka'idar aiki na lantarki inji, kamar yadda aka ce, da aka dogara ne a kan sabon abu daga electromagnetic shigar da, watau, Magnetic Lines na rarrabawa inductor mu sanda jiki. A "mahada" mai yiwuwa ne kawai idan Magnetic filin rotational gudun da inductor - "kofaton" - more yanar gizo gudun. Wannan engine siga - asynchronous gudu - kira "zamewa" da kuma na iya zama har zuwa 7% na rated gudun da stator Magnetic filin.

Matsakaicin Magnetic filin a cikin rata "kofaton", ta sauya sarari matsayi idan aka juya su. A daidai da dokar electromagnetic shigar da, sandan da lantarki tare da "rayuwa da abokin tarayya" - Magnetic filin. Magnetic filayen ne zaman masu alaƙa, hul] a, da kuma ... juya cikin na'ura mai juyi. Real asynchronous motor aiki manufa mayar da daidai kamar yadda aka bayyana a cikin wannan jawabi. All cikakken da'ira - muna da biyu abubuwa ba tare da wani inji connection, amma da juyawa daga daya daga cikinsu, wanda ya karbi na'urar samar da makamashi, rotates wani. An ganuwa "igiya" aiki da Magnetic filin da kofaton maganadisu da sanda.

Don ƙirƙirar engine aka bar kusan kome ba - babu "kofaton" kafin a juya da kuma tilasta wa juyawa Magnetic filin da kansa. A wasu kalmomin, asynchronous motor aiki manufa ya nuna cewa shi Magnetic filin ganiya batu motsa a cikin stator a cikin da'irar, kamar dai shi ne mu juyawa maganadisu. Ya zauna haka al'amarin ga kananan - to "ƙunci" Magnetic filin.

Matsalar da juyawa Magnetic filin da aka warware kamar haka:

• a kan wani fanni na uku nau'i-nau'i daga sandunan - nada - 120 darajõji;
• kowane nada ake kawota ba tare da kalaman daga wani raba Madogararsa. An yi imani da cewa jimlar lokacin zagayowar sinusoid (lokaci) - shi ne 360 digiri. M iyakar ƙarfin lantarki auku a 90 digiri bayan sifili - duk yadda ya koyar a makaranta.
• haskaka ne cewa irin ƙarfin lantarki Maxima faruwa tare da wani na uku lokaci motsa lokaci (electricians ce "uku lokaci-canja 120 digiri") - wannan shi ne mataki na wani shigar da mota manufa. Matsakaicin Magnetic filin ƙarfi ne koma daga na farko zuwa na biyu biyu daga sandunan, sa'an nan da na uku. Sa'an nan ya mayar da aiwatar, wanda yake daidai da motsi, mafi daidai, "juyawa" na Magnetic filin.

Haka ne, kawai, kuma ba tare da fuss, da stator lantarki da makamashi yana tuba zuwa inji motsi na na'ura mai juyi. Don ƙirƙirar wannan mu'ujiza engine, Adam ya dauki 'yan shekarun da suka gabata, mun gani da isasshen minti 15 zuwa ce amincewa: shigar da mota? -No kome sauki.
