Motlakase oa Squirrel Cage Induction ke eng?
Tlhaloso: Mochini oa lesaka la squirrel ke o mong oa mefuta ea lienjene tsa induction. E le ho hlahisa motsamao, o thatafatsa electromagnetism. Kaha shaft ea tlhahiso e hokahane le karolo ea ka hare ea rotor e shebahalang joaloka lesaka. Kahoo e bitsoa lesaka la squirrel. Li-cap tse peli ke hore, tse chitja ka sebopeho li kopantsoe ke li-rotor bars. Tsena li etsoa ho latela EMF ke hore, e hlahisoang ke stator. EMF ena e boetse e hlahisoa ka ntle ho ntlo e entsoeng ka maqephe a tšepe a laminated le terata e kobehileng. Likarolo tse peli tse ka sehloohong tsa mofuta ofe kapa ofe oa motor induction ke stator le rotor. Lesaka la squirrel ke mokhoa o bonolo oa ho hula phello ea induction ea electromagnetic. Mochini oa induction oa lesaka la squirrel oa lipalo tse 4 o bontšitsoe ka tlase.
Molao-motheo oa ho Sebetsa oa Motlakase oa Squirrel Cage
Mosebetsi oa enjene ea induction ea squirrel o ipapisitse le molao-motheo oa electromagnetism. Ha stator winding e fanoa ka thee-phase AC, e hlahisa matla a makenete a potolohang (RMF) a nang le lebelo le bitsoang synchronous speed. RMF ena e baka motlakase o hlahisoang ka har'a li-rotor bars. Kahoo, hona joale ho phalla ka har'a seo. Ka lebaka la maqhubu ana a rotor, matla a makenete a iketsang aa hlahisoa a sebelisanang le stator field. Joale, ho ea ka molao-motheo, tšimo ea rotor e qala ho hanyetsa sesosa sa eona. Ha RMF e tšoara motsotso oa rotor, hona joale ea rotor e theohela ho lefela. Ebe ho ke ke ha e-ba le motsotso o amanang pakeng tsa rotor le RMF.
Ka hona, matla a lefela a tangential a bonoa ke rotor mme a fokotseha ka motsotsoana. Kamora phokotso ena motsotsong wa rotor, motlakase wa rotor o hlohlelletswa hape ke ho tsosoloswa ha motsamao o amanang pakeng tsa RMF le rotor. Kahoo matla a tangential a rotor bakeng sa ho potoloha a tsosoloswa mme a qala ka ho latela RMF. Tabeng ena, rotor e boloka lebelo le sa fetoheng, le leng ka tlase ho lebelo la RMF le lebelo le tsamaellanang. Mona, phapang pakeng tsa lebelo la RMF le rotor e lekanngwa ka mokgwa wa ho thella. Maqhubu a ho qetela a rotor a ka fumanwa ka ho atisa ho thella le maqhubu a phepelo.
Kaho ea Enjene ea Induction ea Lebokose la Squirrel
Likarolo tse hlokahalang bakeng sa kaho ea enjene ea induction ea squirrel cage ke stator, rotor, fene, li-bearing. Stator e na le ho kobeha ha mekhahlelo e meraro ka mechine le ka motlakase, likhato tse 120 tse arohaneng ka nako ea likhato tse tharo tse nang le ntlo ea tšepe le khubu. E le ho fana ka tsela ea ho se rate ho phalla ho bakoang ke motlakase oa AC, ho kobeha ho kentsoe khubung ea tšepe e nang le laminated.
Rotor e fetola matla a motlakase a fuoeng hore e be tlhahiso ea mechini. Shaft, e leng core, e nang le li-current-circuit bars tsa koporo ke likarolo tsa rotor. E le ho qoba hysteresis le maqhubu a eddy a lebisang tahlehelong ea motlakase, rotor e laminated. 'Me ke laela ho thibela ho kobeha, li-conductor lia sotheha e leng se thusang ho fana ka karolelano e ntle ea phetoho.
Fene e hoketsweng ka morao ho rotor bakeng sa phapanyetsano ya mocheso e thusa ho boloka mocheso o le ka tlase ho moedi wa enjene. Bakeng sa ho potoloha ho boreleli, ho na le di-bering ka enjeneng.
