Stator:
Sebopeho sa stator sa di-motor tsa squirrel-cage le di-motor tsa slip-ring se a tshwana. Phapang e kgolo ya di-motor tsa induction tsa slip-ring e hodima sebopeho sa rotor le mokgwa wa tshebetso. Ha di-motor tsa slip-ring di sebediswa ditsamaisong tsa cascade, diphetoho tse ding ho stator di ka etsahala hobane phepelo ya motlakase ya enjene e tswa taolong ya matla ya rotor ya enjene e nngwe ya slip-ring, moo di-resistor tsa kantle di kentsweng ho rotor ya yona.
Rotor:
Lesale la ho thellisa ke eng? Hangata enjene ea lesale la ho thellisa e na le rotor e nang le stator ea leqeba la mohato. Mofuta ona oa rotor o na le lebili la mekhahlelo e meraro le ajoang, le entsoeng ka likhoele tse sebelisoang jenereithara ea AC. Karolo ea rotor e entsoe ka li-lamination tsa tšepe 'me e na le likheo tse amohelang li-winding tsa mekhahlelo e meraro tse entsoeng ka mohato o le mong. Li-winding tsena li arotsoe ka motlakase ka likhato tse 120. Esita le haeba stator e leketlile ka mekhahlelo e 'meli, palo ea li-winding tsa stator tse leketlile rotor e tšoana le palo e ho stator 'me kamehla ke ea mekhahlelo e meraro. Li-winding tsena tse tharo li tsamaisoa ho tsoa pheletsong e 'ngoe ka hare 'me li hokahantsoe le mehele e meraro ea ho thellisa e kentsoeng shaft ea rotor ka boeona. Li-terminal tse tharo li ikopanya le mehele ena e meraro ea ho thellisa ka thuso ea li-brush tsa carbon, tse behiloeng meheleng ke likarolo tsa selemo. Li-brush tsena tse tharo tsa carbon li hokahantsoe ka ntle ho rheostat ea khokahano ea mekhahlelo e meraro ea ho qala. Lesale la ho thellisa le rheostat ea kantle li ka eketsa khanyetso ea kantle ea potoloho ea rotor, e etsang hore e be le khanyetso e phahameng nakong ea ho qala, ka hona e eketsa torque ea ho qala. Tlas'a maemo a tloaelehileng a ts'ebetso, lesale la ho thellisa le phethela potoloho ka bohona ka lesale la letsoho la tšepe. Lesale la letsoho la tšepe le sutumelletsoa ka har'a shaft, e leng se etsang hore mehele e meraro e kopane. Ho phaella moo, borashe bo phahama ka bohona ho tloha lesale la ho thellisa ho qoba tahlehelo le ho tsofala ha khohlano. Tlas'a maemo a tloaelehileng a ts'ebetso, ts'ebetso ea rotor ea lesale la ho thellisa e tšoana le ea rotor ea squirrel-cage.
Ho tla etsahala'ng haeba ho eketsoa resistor ea kantle? Tabeng ea li-motor tsa induction tsa squirrel-cage, khanyetso ea rotor e tlase haholo, kahoo hona joale ka har'a rotor e phahame haholo, e leng se etsang hore torque ea ho qala e mpefale. Leha ho le joalo, haeba resistor ea kantle e eketsoa tabeng ea li-motor tsa slip-ring, khanyetso ea rotor e eketseha ha ho qala, kahoo hona joale ea rotor e tlase 'me torque ea ho qala e phahame haholo. Ho feta moo, ho thella ho hlokahalang ho hlahisa torque e phahameng ho lekana le khanyetso ea rotor. Li-motor tsa slip-ring, ka ho eketsa resistor ea kantle ho eketsa khanyetso ea rotor, ho thella hoa eketseha. Ka lebaka la khanyetso e phahameng ea rotor, ho thella ho hoholo, kahoo esita le ka lebelo le tlase, torque ea "hula-ntle" e ka finyelloa. Ha enjene e fihla lebelong la eona la motheo (lebelo le felletseng), ha resistor ea kantle e tlosoa 'me tlas'a maemo a tloaelehileng a ts'ebetso, mokhoa oa eona oa ts'ebetso o tšoana le oa li-motor tsa induction tsa squirrel-cage. Ka hona, li-motor tsena li loketse haholo meroalo e phahameng haholo ea inertia, e hlokang hoo e batlang e le zero torque ea ho hula-ntle ka lebelo le tlase le ho potlakisa ho fihlela lebelo le felletseng, 'me e monya hona joale e fokolang ka nako e khuts'oane haholo.
Melemo ea li-motor tsa induction tsa slip-ring:
Molemo o moholo oa li-motor tsa induction tsa slip-ring ke hore li kaho laoloa habonolo ka lebelo.Esita le ka lebelo la lefela, "torque ea ho hula" e ka finyelloa. Ha e bapisoa le li-induction motors tsa squirrel-cage, e na le torque e phahameng ea ho qala. Torque ea mojaro o felletseng ke hoo e ka bang 200-250% ea torque ea mojaro o felletseng. Li-induction motors tsa squirrel-cage li etsa 600-700% ea current ea mojaro o felletseng, empa starting current ea li-induction motors tsa slip-ring e tlase haholo, hoo e ka bang 250-350% ea current ea mojaro o felletseng.
