Enjene ea karolo e le 'ngoe ea asynchronous ke enjene e hlokang feela motlakase oa karolo e le' ngoe ea AC. Mohato o le mong oa asynchronous motor o na le stator, rotor, bearing, casing, end cover, joalo-joalo Stator e na le foreimi le mokokotlo oa tšepe o nang le mapheo. Mokotla oa tšepe o entsoe ka lishiti tsa tšepe tsa silicon tse phunyeletsoeng le tse entsoeng ka laminated ka li-grooves. Lihlopha tse peli tsa mapheo a maholo (a boetseng a bitsoa runings windings) le matsoelintsoeke a thusang (hape a bitsoa matsoelintsoeke a qalang a etsang matsoelintsoeke a thusang) a arohaneng ka 90° a kentsoe ka har'a li-grooves. The matsoelintsoeke ka sehloohong e amana le phepelo ea motlakase AC, 'me matsoelintsoeke thusang e amana letoto la lihlooho tse ho centrifugal switjha S kapa ho qala capacitor, matha capacitor, joalo-joalo, 'me joale e amanang le phepelo ea matla. Rotor ke rotor ea aluminium ea mofuta oa cage. Mokotla oa tšepe o entsoe ka laminated ebe aluminiamo e lahleloa ka har'a sekotjana sa mokokotlo oa tšepe. Mehele ea ho qetela e boetse e lahleloa hammoho ho khutsufatsa mekoallo ea tataiso ea rotor hore e be mofuta oa squirrel-cage.
Mohato o le mong oa li-asynchronous motors li arotsoe hape ka li-motor tse nang le mohato o le mong oa ho hanyetsa-ho qala li-asynchronous motors, li-motor tse nang le karolo e le 'ngoe ea capacitor-start asynchronous motors, li-motor asynchronous motors tse nang le karolo e le' ngoe le mekhahlelo e le 'ngoe ea likarolo tse peli tsa boleng ba capacitor asynchronous motors.
2.Mohaho oa motheo oa motlakase oa asynchronous oa mekhahlelo e meraro
Enjene ea asynchronous ea mekhahlelo e meraro e na le stator, rotor le libering. The stator e haholo-holo entsoe ka tšepe core, tse tharo-mohato matsoelintsoeke, foreime le qetellong sekoahelo. Mokotla oa stator ka kakaretso o phunyeletsoa le ho etsoa laminated ho tloha ho 0.35 ~ 0.5 limilimithara tse teteaneng tsa silicon tse nang le lesela le sireletsang holim'a metsi. Ho na le li-slots tse arotsoeng ka mokhoa o lekanang tse phunyeletsoeng ka har'a selikalikoe se ka hare sa mantlha ho kenya li-winding tsa stator. Mohaho oa mekhahlelo e meraro o entsoe ka mapheo a mararo a nang le sebopeho se tšoanang se arohaneng ka 120 ° ho tloha ho tse ling 'me li hlophisitsoe ka ho lekana. Coil e 'ngoe le e' ngoe ea li-winding tsena e kenngoa ka har'a slot e 'ngoe le e' ngoe ea stator ho latela melao e itseng. Mosebetsi oa eona ke ho feta ka mekhahlelo e meraro e fapanyetsanang hona joale le ho hlahisa matla a khoheli a potolohang. Hangata setsi se entsoe ka tšepe e entsoeng ka tšepe. Motheo oa li-motor tse kholo tsa asynchronous hangata li cheselitsoe ka lipoleiti tsa tšepe. Motheo oa li-motors tse nyane o entsoe ka aluminium e entsoeng ka tšepe. Mosebetsi oa eona ke ho lokisa mokokotlo oa stator le likoahelo tse ka pele le tse ka morao ho tšehetsa rotor, le ho phetha karolo ea ho sireletsa le ho senya mocheso. Ho na le likhopo tse senyang mocheso ka ntle ho motheo oa motlakase o kentsoeng ho eketsa sebaka sa ho senya mocheso. Likhurumetso tsa ho qetela lipheletsong tse peli tsa motheo oa enjene e sirelelitsoeng li na le masoba a moea ho lumella phepelo e tobileng ea moea kahare le kantle ho enjene ho tsamaisa phepelo ea mocheso. Sekoahelo sa ho qetela se phetha karolo ea ho lokisa rotor, ho e tšehetsa le ho e sireletsa. The rotor haholo-holo e entsoe ka tšepe core le windings.
Motsoako oa rotor o entsoe ka thepa e tšoanang le ea stator. E hlajoa ka litebele le laminated ho tloha 0.5 mm thick silicon sheet sheets. Selika-likoe se ka ntle sa lishiti tsa tšepe tsa silicon se phunyeletsoa ka likoti tse arotsoeng ka ho lekana bakeng sa ho beha li-rotor windings. Hangata, selikalikoe se ka hare sa letlapa la tšepe la silicon le phunyeletsoeng ho tloha setsing sa stator se sebelisetsoa ho otla mokokotlo oa rotor. Ka kakaretso, mokokotlo oa rotor oa li-asynchronous motors o hatelloa ka ho toba mokokotlong o potolohang, ha mokokotlo oa rotor oa li-asynchronous motors tse kholo le tse mahareng (bophara ba rotor bo fetang 300 ~ 400 mm) o hatelloa holim'a shaft e potolohang ka thuso ea bracket ea rotor.
