Kungani izinjini eziningi zemishini yasendlini zisebenzisa ama-pole motors anemithunzi, futhi yiziphi izinzuzo?

I-shaded pole motor iyi-self-starting AC single-phase induction motor elula, okuyimoto encane ye-squirrel cage, enye yayo ezungezwe indandatho yethusi, ebizwa nangokuthi indandatho yesigxobo esinomthunzi noma indandatho yesigxobo esinomthunzi.Indandatho yethusi isetshenziswa njengokuvunguza kwesibili kwenjini.Izici eziphawulekayo ze-shaded-pole motor ukuthi isakhiwo silula kakhulu, akukho ukushintsha kwe-centrifugal, ukulahlekelwa kwamandla e-shaded-pole motor kukhulu, into yamandla emoto iphansi, kanye ne-torque yokuqala nayo iphansi kakhulu. .Zenzelwe ukuthi zihlale zizincane futhi zibe nezilinganiso zamandla aphansi.Ijubane lama-motor linembe njengemvamisa yamandla asetshenziswa ezinjinini, ezivame ukusetshenziselwa ukushayela amawashi.Ama-motor ane-shaded pole azungeza kuphela ohlangothini olulodwa, injini ayikwazi ukujikeleza ibheke kolunye uhlangothi, ukulahleka okukhiqizwa amakhoyili e-shaded-pole, ukusebenza kahle kwemoto kuphansi, futhi ukwakheka kwawo kulula, lawa ma-motor asetshenziswa kakhulu kubalandeli basekhaya. nezinye izinto ezisetshenziswayo ezinamandla amancane.

Isebenza kanjani i-Pole Motor ene-Shaded

I-Shaded-pole motor iyinjini yokungenisa isigaba esisodwa se-AC.I-axiliary winding yakhiwe izindandatho zethusi, ezibizwa ngokuthi ikhoyili ye-shaded-pole.I-current in the coil ibambezela isigaba sokuguquguquka kazibuthe engxenyeni yesigxobo sikazibuthe ukuze kuhlinzekwe inkambu yakazibuthe ezungezayo.Isiqondiso sokuzungezisa sisuka esigxotsheni esinganomthunzi.eringini yesigxobo esinomthunzi.

Amakhoyili ezigxobo ezinomthunzi (amasongo) aklanywe ngendlela yokuthi i-eksisi yesigxobo sikazibuthe isuswe e-axis yesigxobo esikhulu, futhi ikhoyili yamagnetic field kanye namakhoyili epali anomthunzi engeziwe asetshenziselwa ukukhiqiza inkambu kazibuthe ejikelezayo ebuthaka.Lapho i-stator inikwa amandla, ukuguquguquka kazibuthe kwemizimba yesigxobo kudala i-voltage kumakhoyili esigxobo esinomthunzi, okusebenza njengokuphenduka kwesibili kwe-transformer.I-current in the second winding of the transformer ayivumelaniswa ne-current in the primary winding, futhi ukugeleza kazibuthe kwesigxobo esinomthunzi akuvumelaniswa nokuguquguquka kazibuthe kwesigxobo esikhulu.

Enjinini ene-shaded pole, i-rotor ifakwa ku-c-core elula, futhi ingxenye yesigxobo ngasinye imbozwa ikhoyili ene-shaded-pole ekhiqiza i-pulsating flux lapho i-alternating current idlula ikhoyili yokuhlinzeka.Lapho ukuguquguquka kukazibuthe kukhoyili ye-shading kushintsha, i-voltage kanye namanje kudonswa kukhoyili yesigxobo esinomthunzi, okuhambisana noshintsho ku-flux kazibuthe kusuka kukhoyili yamandla.Ngakho-ke, ukugeleza kazibuthe ngaphansi kwekhoyili yesigxobo esinomthunzi kubambezela ukugeleza kazibuthe kuyo yonke ikhoyili.Ukujikeleza okuncane kukhiqizwa ku-flux magnetic yi-rotor, ukuze i-rotor ijikeleze.Isibalo esilandelayo sibonisa imigqa ye-magnetic flux etholwe ukuhlaziywa kwesici esilinganiselwe.

Isakhiwo SeMoto Esinomthunzi

I-rotor kanye nesitimela sayo segiya lokunciphisa elihlobene kufakwe ku-aluminium, ithusi noma izindlu zepulasitiki.I-rotor evaliwe iqhutshwa ngozibuthe endlini.Amagiya anjalo amagiya ngokuvamile ane-shaft yokugcina ephumayo noma igiya elizungeza ukusuka ku-600 rpm kuye ku-1 ngehora./168 ukuvukela (inguquko eyodwa ngesonto).Njengoba ngokuvamile kungekho indlela ecacile yokuqala, i-rotor ye-motor enikwe amandla yi-frequency supply njalo kufanele ibe lula kakhulu ukuze ikwazi ukufinyelela isivinini sokusebenza ngaphakathi komjikelezo owodwa we-frequency supply, i-rotor ingahlonyiswa ngekheji ye-squirrel, ukuthi i-motor iqala njenge-induction motor, uma i-rotor Idonswa ukuze ivumelanise nozibuthe wayo, akukho okwamanje okubangelwa i-squirrel cage ngakho-ke ayisadlala indima ekusebenzeni, ukusetshenziswa kokulawula imvamisa okuguquguqukayo kwenza i-pole motor emthunzini. ukuqala kancane futhi ulethe i-torque eyengeziwe.

Injini yesigxobo esinomthunziisivinini

Isivinini se-pole motor esinomthunzi sincike ekwakhiweni kwenjini, isivinini esivumelanayo (isivinini lapho insimu kazibuthe ye-stator izungeza) sinqunywa imvamisa yamandla we-AC wokufaka kanye nenani lezigxobo ku-stator.Izigxobo ezengeziwe zekhoyili, isivinini esivumelanayo sihamba kancane, imvamisa ye-voltage esetshenziswayo iyanda, isivinini esivumelanayo siphezulu, imvamisa kanye nenani lezigxobo akuzona izinto eziguquguqukayo, isivinini esivamile sokuvumelanisa se-60HZ motor ngu-3600, 1800, 1200. futhi 900 rpm.Kuncike enanini lezigxobo ekwakhiweni kwasekuqaleni.

Ekuphetheni

Njengoba i-torque yokuqala iphansi futhi ayikwazi ukukhiqiza i-torque eyanele ukuvula imishini emikhulu, ama-pole motors ane-shaded angenziwa kuphela ngamasayizi amancane, ngaphansi kwama-watts angu-50, izindleko eziphansi futhi ezilula kubalandeli abancane, ukujikeleza komoya nezinye izinhlelo zokusebenza ze-torque eziphansi.Isivinini se-motor singancishiswa ngokusabela kochungechunge ukuze kubekwe umkhawulo wamanje ne-torque, noma ngokushintsha inombolo yokuphenduka kwekhoyili yemoto.
