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

I-pole motor ene-shaded 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. kwendandatho yesigxobo enomthunzi.

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.
