Ama-motor endandatho yokushelela, ezaziwa nangokuthi ama-wold rotor motors, ziyisisekelo samaningiizinhlelo zokusebenza zokudlulisa amandla aphezulu.Zisetshenziswa kabanzi ezimbonini zezinto zokusetshenziswa ezifanaukumbiwa kwezimayini, izimboni zezinto zokusetshenziswa kwezimbiwa or izimboni zokunamathiselanjengesamente, i-limestone, ne-gypsum ezinqubweni ezahlukahlukene zokuchoboza, ukucindezela ama-roller, kanye nokugaya. Zisetshenziswa futhi kumafeni amakhulu, amaphampu, kanye nama-conveyor.
I-stator:
Isakhiwo se-stator sama-motor e-squirrel-cage kanye nama-motor e-slip-ring siyafana. Umehluko omkhulu wama-motor e-slip-ring induction usesimeni se-rotor kanye nemodi yokusebenza. Uma ama-motor e-slip-ring esetshenziswa ezinhlelweni ze-cascade, ezinye izinguquko ku-stator zingase zihlangatshezwe ngoba ukunikezwa kwamandla kwemoto kuvela ekulawulweni kwamandla kwe-rotor yenye imoto e-slip-ring, lapho kufakwa khona ama-resistors angaphandle ku-rotor yayo.
I-Rotor:
Iyini indandatho yokushelela? Injini yendandatho yokushelela ivame ukuba ne-rotor ene-stator ye-phase-wound. Lolu hlobo lwe-rotor lune-wiring ephindwe kabili enezigaba ezintathu, eyakhiwa ama-coil asetshenziswa ku-AC generator. I-rotor core yenziwe ngama-lamination ensimbi futhi inezikhala zokwamukela ama-windings esigaba esisodwa esigaba ezintathu. La ma-windings ahlukaniswe ngogesi ngama-degrees angu-120. Ngisho noma i-stator iboshwe ngezigaba ezimbili, inani lama-windings e-stator eliboshwe ku-rotor lifana nenombolo eku-stator futhi lihlala liyizigaba ezintathu. La ma-windings amathathu aholwa ngaphandle komunye umkhawulo ngaphakathi futhi axhunywe kuma-slip rings amathathu afakwe ku-rotor shaft uqobo. Ama-terminals amathathu axhumana nala ma-slip rings amathathu ngosizo lwamabhulashi e-carbon, aqiniswe emasongweni yizingxenye zasentwasahlobo. Lawa mabhulashi e-carbon amathathu axhunywe ngaphandle ku-rheostat yokuxhumanisa yesigaba ezintathu. Indandatho yokushelela kanye ne-rheostat yangaphandle kungandisa ukumelana kwangaphandle kwesekethe ye-rotor, okwenza ibe nokumelana okuphezulu ngesikhathi sokuqalisa, ngaleyo ndlela kwandiswe i-torque yokuqala. Ngaphansi kwezimo zokusebenza ezijwayelekile, indandatho yokushelela iqedela ngokuzenzakalelayo isekethe ngendandatho yesikhafu sensimbi. Indandatho yesikhafu sensimbi isunduzwa eceleni kweshafti, okwenza amasongo amathathu athintane. Ngaphezu kwalokho, amabhulashi aphakama ngokuzenzakalelayo kusuka endandatho yokushelela ukuze agweme ukulahlekelwa ukungqubuzana nokuguguleka. Ngaphansi kwezimo zokusebenza ezijwayelekile, umsebenzi we-rotor yendandatho yokushelela ufana nowe-rotor ye-squirrel-cage.
Kuzokwenzekani uma kufakwa i-resistor yangaphandle? Endabeni yama-motor okungenisa i-squirrel-cage, ukumelana kwe-rotor kuphansi kakhulu, ngakho-ke ugesi ku-rotor uphakeme kakhulu, okwenza i-torque yokuqala ibe yimbi kakhulu. Kodwa-ke, uma i-resistor yangaphandle ingeziwe endabeni yama-motor okungena, ukumelana kwe-rotor kuyanda ekuqaleni, ngakho-ke ugesi we-rotor uphansi futhi ugesi wokuqala uphezulu. Ngaphezu kwalokho, ukushelela okudingekayo ukuze kukhiqizwe i-torque ephezulu kuhambelana nokumelana kwe-rotor. Kuma-motor okungena, ngokwandisa i-resistor yangaphandle ukuze kwandiswe ukumelana kwe-rotor, ukushelela kuyanda. Ngenxa yokumelana okuphezulu kwe-rotor, ukushelela kukhulu, ngakho-ke ngisho nangejubane eliphansi, i-torque "yokudonsa" ingatholakala. Lapho imoto ifinyelela ijubane layo eliyisisekelo (ijubane eligcwele), lapho i-resistor yangaphandle isuswa futhi ngaphansi kwezimo zokusebenza ezijwayelekile, imodi yayo yokusebenza ifana neye-motor okungenisa i-squirrel-cage. Ngakho-ke, lawa ma-motor afaneleka kakhulu emithwalweni ephezulu kakhulu ye-inertia, edinga cishe i-torque yokudonsa engenalutho ngesivinini esiphansi kanye nokusheshisa ijubane eligcwele, futhi imunce ugesi omncane ngesikhathi esifushane kakhulu.
Izinzuzo zama-induction motors anezindandatho ezishelelayo:
Inzuzo eyinhloko yama-induction motors e-slip-ring ukuthi angakwaziilawulwa kalula ngesivinini.Ngisho noma ijubane lingekho, “i-torque yokudonsa” ingafinyelelwa. Uma kuqhathaniswa nama-induction motors e-squirrel-cage, ine-torque yokuqala ephezulu. I-torque egcwele umthwalo cishe ingu-200-250% we-torque egcwele umthwalo. Ama-induction motors e-squirrel-cage aqukethe u-600-700% wamandla omthwalo ogcwele, kodwa amandla okuqala ama-induction motors e-slip-ring aphansi kakhulu, cishe angu-250-350% wamandla omthwalo ogcwele.
