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.Iimotor ezinomthunzi zijikeleza kuphela kwicala elinye, i-motor ayikwazi ukujikeleza kwelinye icala, ilahleko eveliswa zii-coil zepali ezinomthunzi, 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 njengomoya wesibini we-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.
