Imashini ihindura ingufu z'amashanyarazi mo ingufu za mekanike yitwa moteri y'amashanyarazi. Izi ni moteri zoroshye mu miterere, zikoreshwa byoroshye, zihendutse, zikora neza cyane, zidakorerwa isuku nke, kandi zizewe. Moteri z'amashanyarazi zifite ibice bitatu ni zimwe muri zo kandi zitandukanye n'izindi moteri z'amashanyarazi. Itandukaniro rikomeye ni uko nta miyoboro y'amashanyarazi ihuza rotor n'isoko iyo ari yo yose itanga. Umuriro n'amashanyarazi bikenewe muri rotor circuit bitangwa na induction iva kuri stator winding. Iyi niyo mpamvu twayita moteri y'amashanyarazi. Iyi nkuru ivuga kuri moteri y'amashanyarazi ya Squirrel cage, imwe mu moko ya moteri z'amashanyarazi zifite ibice bitatu.
Moteri yo Gutwara Imodoka ya Squirrel Cage ni iki?
Ibisobanuro: Moteri y'akazu k'umushongi ni imwe mu moko ya moteri zitwara imizigo. Kugira ngo ikore ingendo, ikomeza ingufu za electromagnetism. Kubera ko umugozi usohoka uhujwe n'igice cy'imbere cya rotor gisa n'akazu. Bityo yitwa akazu k'umushongi. Udupfundikizo tw'impande ebyiri ni ukuvuga uruziga mu ishusho y'uruziga duhujwe n'imirongo ya rotor. Ibi bikorwa hashingiwe kuri EMF ni ukuvuga, ikorwa na stator. Iyi EMF kandi ikorwa n'inyuma ikozwe mu mpapuro z'icyuma za laminated hamwe n'insinga zizunguruka. Ibice bibiri by'ingenzi by'ubwoko bwose bwa moteri zitwara imizigo ni stator na rotor. Akazu k'umushongi ni uburyo bworoshye bwo gukurura ingaruka za electromagnetic induction. Moteri y'akazu k'umushongi ka 4-pole igaragara hano hepfo.
Ihame ry'imikorere ya moteri ya Squirrel Cage Induction
Imikorere ya moteri ya Squirrel induction ishingiye ku ihame rya electromagnetism. Iyo stator winding ihawe AC ya thee-phase, ikora magnetic field izenguruka (RMF) ifite umuvuduko witwa synchronous speed. Iyi RMF itera voltage iterwa na rotor bars. Rero, iyo power inyura muri iyo. Bitewe n'iyi rotor currents, self magnetic field irakorwa ikorana na stator field. Noneho, nk'uko ihame ribivuga, rotor field itangira guhangana n'impamvu yayo. Iyo RMF ifashe rotor moment, rotor current iragabanuka ikagera kuri zeru. Icyo gihe nta gihe cyaba kiri hagati ya rotor na RMF.
Bityo, imbaraga za zeru tangential zigerwaho na rotor hanyuma zikagabanuka akanya gato. Nyuma y'uku kugabanuka mu kanya ka rotor, umuyoboro wa rotor wongera guterwa no kongera kubaka ingendo hagati ya RMF na rotor. Bityo imbaraga za tangential za rotor zo kuzenguruka zirasubizwa hanyuma zigatangira gukurikira RMF. Muri iki gihe, rotor igumana umuvuduko uhoraho, uri munsi y'umuvuduko wa RMF n'umuvuduko uhuza. Aha, itandukaniro riri hagati y'umuvuduko wa RMF na rotor ripimwa mu buryo bwo kunyerera. Inshuro ya nyuma ya rotor ishobora kuboneka binyuze mu gukuba inshuro zo kunyerera n'inshuro zo gutanga.
Kubaka Moteri Itwara Induction mu Kigega cya Squirrel
Ibice bikenewe mu kubaka moteri itwara amashanyarazi ni stator, rotor, fan, bearing. Stator igizwe n'imizunguruko y'amashanyarazi n'iy'amashanyarazi ya dogere 120 hagati yayo, ifite aho ikorera icyuma n'iy'imbere. Kugira ngo hatangwe inzira yo kudashaka guhindagurika kw'amashanyarazi aturuka ku muyoboro wa AC, imizunguruko ishyirwa ku cyuma gifite laminated.
Rotor ihindura ingufu z'amashanyarazi zitangwa mu buryo bwa mekanike. Umugozi, igice cy'imbere, imigozi y'umuringa ifite umurongo mugufi ni ibice bya rotor. Kugira ngo hirindwe hysteresis n'imigezi ishyushye ituma umuriro ubura, rotor irapfundikirwa. Kandi ndategeka ko wirinde ko amazi agwa, ibyuma biragoramye, binafasha gutanga igipimo cyiza cyo guhindura.
Umufana ufatanye inyuma ya rotor kugira ngo ubushyuhe buhinduke bufasha mu kuguma munsi y'ubushyuhe ntarengwa bwa moteri. Kugira ngo izunguruke neza, moteri irakoresha uburyo bwo gufunga.
Itandukaniro riri hagati ya Squirrel Cage Induction Motors na Slip Ring Induction Motors.
Ibyiza
Ibyiza bya moteri ikoresha squirrel cage birimo ibi bikurikira:
Imiterere yoroshye kandi ikomeye.
Igiciro gito cy'ibanze ndetse n'ikiguzi cyo kubungabunga.
Igumana umuvuduko uhoraho.
Ubushobozi bwo gusimbuza ibintu byinshi ni bwinshi.
Gutangira byoroshye.
Ingufu nyinshi.
Umuringa wa rotor ugabanuka cyane.
Ubushobozi buhanitse.
Imbogamizi
Ingaruka mbi za moteri y’ikiraro cy’inkoko zirimo ibi bikurikira.
Moteri
Umuvuduko wo gutangira ufite imbaraga nyinshi
Ifite ingaruka zikomeye ku ihindagurika ry'amashanyarazi atangwa
Ingufu nke ku mutwaro woroheje.
Kugenzura umuvuduko biragoye cyane
Umuvuduko muke wo gutangira bitewe n'uko rotasiyo yayo idakora neza.
