Kutheni le nto uninzi lweenjini zezixhobo zendlu zisebenzisa iimotor ezifakwe umthunzi, kwaye zeziphi iingenelo?

I-shaded pole motor yinto elula yokuqalisa i-AC yesigaba esisodwa se-motor induction, eyimoto encinci ye-squirrel cage, enye ejikelezwe ngumsesane wobhedu, obizwa ngokuba ngumsesane wepali enomthunzi okanye umsesane wepali.Iringi yobhedu isetyenziswa njengomoya wesibini wenjini.Iimpawu eziphawulekayo zemoto ene-shaded-pole kukuba ubume bulula kakhulu, akukho switshi ye-centrifugal, ukulahleka kwamandla emoto enomthunzi kukhulu, amandla emoto aphantsi, kwaye i-torque yokuqala nayo iphantsi kakhulu. .Ziyilelwe ukuba zihlale zincinci kwaye zinemilinganiselo yamandla aphantsi.Isantya seenjini sichanekile njengokuphindaphindwa kwamandla asetyenziswa kwiimotor, ezihlala zisetyenziselwa ukuqhuba iiwotshi.Iinjini ezineepali ezinomthunzi zijikeleza kuphela kwicala elinye, i-motor ayikwazi ukujikeleza kwelinye icala, ilahleko eyenziwe ziikhoyili ezifakwe umthunzi, ukusebenza kakuhle kwemoto kuphantsi, kwaye ubume bayo bulula, ezi motor zisetyenziswa kakhulu kubalandeli basekhaya. kunye nezinye izixhobo zombane ezincinci.

Isebenza njani iMoto yePole eneShaded

Imoto ene-Shaded-pole motor yi-AC enenqanaba elinye lokungenisa.I-winding encedisayo yenziwe ngamakhonkco obhedu, abizwa ngokuba yi-shaded-pole coil.I-current in the coil ilibazisa isigaba se-magnetic flux kwi-pole pole ye-magnetic part ukwenzela ukubonelela ngentsimi yamagnetic ejikelezayo.Isalathiso sokujikeleza sisuka kwipali engenamthunzi.kwikhonkco lepali elinomthunzi.

Iikhoyili zeepali ezinomthunzi (amakhonkco) ziyilwe ukuze i-axis yesibonda sozibuthe isuswe kwi-axis yepali yepali ephambili, kwaye i-coil yomhlaba wemagnethi kunye neekhoyili zeepali ezinomthunzi ezongezelelweyo zisetyenziselwa ukuvelisa umhlaba obuthathaka ojikelezayo.Xa i-stator inikwe amandla, i-magnetic flux yemizimba yesibonda idala i-voltage kwiikhoyili zepali ezinomthunzi, ezisebenza njenge-second winding ye-transformer.I-current in the second winding of the transformer is not synced with current in the primary winding, kunye ne-magnetic flux ye-pole shaded ayihambelani ne-magnetic flux ye-pole main.

Kwi-motor-pole motor, i-rotor ifakwe kwi-c-core elula, kwaye isiqingatha sepali ngasinye sigqunywe yi-coil ene-shaded-pole eyenza i-pulsating flux xa i-alternating current idlula kwi-coil yokubonelela.Xa i-magnetic flux ngokusebenzisa i-coil ye-shading itshintsha, i-voltage kunye ne-current ifakwe kwi-coil yesibonda esinomthunzi, ehambelana nokutshintsha kwe-magnetic flux ukusuka kwikhoyili yamandla.Ke ngoko, ukuqukuqela kazibuthe phantsi kwekhoyili yepali enomthunzi ibeka i-magnetic flux kuyo yonke ikhoyili.Ukujikeleza okuncinci kuveliswa kwi-flux magnetic yi-rotor, ukwenzela ukuba i-rotor ijikeleze.Lo mzobo ulandelayo ubonisa imigca eguquguqukayo yamagnetic efunyenwe luhlalutyo lwento elinganiselweyo.

ISakhiwo seMoto esinoMthunzi

I-rotor kunye nololiwe ohambelana nawo wokunciphisa izixhobo zifakwe kwi-aluminium, ubhedu okanye indlu yeplastiki.I-rotor evaliweyo iqhutywe ngemagnethi kwizindlu.Iimoto zegiya ezinjalo zihlala zine-shaft yokugqibela ephumayo okanye igiya ejikeleza ukusuka kwi-600 rpm ukuya kwi-1 ngeyure./168 revolutions (1 revolution ngeveki).Ekubeni ngokuqhelekileyo akukho ndlela icacileyo yokuqalisa, i-rotor yemoto enikwe amandla okunikezelwa rhoqo kufuneka ibe lula kakhulu ukuze ikwazi ukufikelela kwisantya sokusebenza ngaphakathi komjikelo omnye we-frequency yonikezelo, i-rotor inokuxhotyiswa nge-squirrel cage, ngoko ke. ukuba i-motor iqala njenge-motor induction, xa i-rotor itsalwa ukuba ihambelane nemagnethi yayo, akukho nto ikhoyo ngoku kwikheji ye-squirrel kwaye ngenxa yoko ayisadlali indima ekusebenzeni, ukusetyenziswa kokulawula okuguquguqukayo okuguquguqukayo kwenza ukuba i-pole motor ibe nomthunzi. ukuqala kancinci kwaye uhambise itorque eyongezelelweyo.

Imoto yepali enomthunziisantya

Isantya semoto esinomthunzi sixhomekeke kuyilo lwemoto, isantya esilungelelanisiweyo (isantya apho i-stator magnetic field ijikelezayo) simiselwa ngokuphindaphindiweyo kwegalelo le-AC amandla kunye nenani leepali kwi-stator.Iipali ezininzi zekhoyili, isantya esicothayo se-synchronous, ukuphakama kwe-voltage esetyenziswayo ephezulu, isantya esiphezulu se-synchronous, i-frequency kunye nenani leepali aziguquki, isantya esiqhelekileyo se-synchronous ye-60HZ motor yi-3600, i-1800, i-1200 kunye ne-900 rpm.Kuxhomekeke kwinani leepali kuyilo lokuqala.

ukuququmbela

Ekubeni i-torque yokuqala iphantsi kwaye ayikwazi ukuvelisa i-torque eyaneleyo yokuguqula izixhobo ezinkulu, ii-motor poles ezinomthunzi zingenziwa kuphela ngobukhulu obuncinci, ngaphantsi kwe-50 watts, ixabiso eliphantsi kunye nelula kubalandeli abancinci, ukujikeleza komoya kunye nezinye izicelo eziphantsi ze-torque.Isantya semoto sinokuncitshiswa ngokusabela kothotho ukukhawulela okwangoku kunye netorque, okanye ngokutshintsha inani leekhoyili zeemoto ezijikayo.
