Advanced system tsim thiab qhov chaw raug npaum thiab zog-saving lub cev muaj zog
Tsav muab ntau tshaj 60% ntawm muaj fais fab, ua hauj lwm zoo yog ib tug tseem ceeb tsim parameter, thiab cov efficiency ntawm lub cev muaj zog tsim yog tseem ceeb dua puas tau. Efficiency yog txhais raws li tus piv ntawm tus neeg kho tshuab hwj chim tauj mus rau lub hwj chim muab. Ib tug lub cev muaj zog nrog ib tug ua hauj lwm zoo ntawm 85% converts 85% ntawm hluav taws xob mus rau hauv cov neeg kho tshuab zog, thiab tshuav 15% yog siv raws li thaum tshav kub kub dissipation.
Lub zog-saving lub cev muaj zog koom tes nrog high-zoo cov ntaub ntawv thiab optimized tsim mus cuag dua efficiency. Piv txwv li, lub siab lub txhuas cov ntsiab lus nyob rau hauv lub rotor, ntau dua qhov lub qhov filling coefficient nyob rau hauv lub stator thiab tus me tus kuj tsis tau. Optimized rotor qauv thiab rotor stator cua kis txo stray load tsis tau. Cov paub tsim ntawm kiv cua txias ua rau koj tsis tau kev cua kuj tsav txias yam tsawg kawg nkaus. Lub rotor thiab stator tub ntxhais txais yuav dua zoo thiab thinner steel laminations,
uas yuav zoo heev txo lub magnetization tsis tau. Thaum kawg, tus yuav txo tau ntawm kev sib txhuam tsis yog tshwm sim los ntawm ntau dua zoo bearings. Cov nram qab no daim duab qhia tau hais tias cov tawg daim duab ntawm AC induction lub cev muaj zog, cim tias seb thaum lub plhaub thiab kabmob Cheebtsam.
- Optimization ntawm rotor / stator lamination loj thiab zoo ntawm steel siv
1.1 hysteresis poob thiab eddy tam sim no tsis yog hu ua cov tub ntxhais tsis ua ke. Hais txog 20% ntawm tag nrho cov tsis yog tshwm sim los ntawm eddy tam sim no thiab cov tub ntxhais saturation. Lub eddy tam sim no generated nyob rau hauv lub lamination tsiv txheeb ze rau cov kev hloov magnetic teb, uas yuav ua rau kuv haj hwj chim tsis tau. Laminated stator cores txo eddy tam sim no losses, uas yuav tsum tau tsis tshua los ntawm ntau laminations raws li nyob rau hauv hlau loj, resistivity, ceev, thickness, zaus, thiab flux ceev.
1.2 lub hysteresis tsis yog ua thaum lub flux ntawm lub magnetic Circuit Court pheej hloov. Feem ntau ntawm cov load ntaub ntawv siv nyob rau hauv lub cev muaj zog yog steel siv rau lub stator thiab rotor cores. Los ntawm kev txo lub lamination thickness, cov flux ceev thiab cov tub ntxhais tsis muaj nyoog. Cov zoo dua qib lamination steel yuav tau xaiv los ntawm Annealing hloov lub grain qauv rau magnetization thiab txo lub hysteresis tsis tau. Lub eddy tam sim no tsis yog txo los ntawm nce lub resistivity ntawm lub steel muaj pob zeb ntais, tab sis lub pob zeb ntais cov ntsiab lus tsub kom tus tuag coj thaum lub sij hawm stamping vim hais tias nws yuav tsub kom lub hardness ntawm lub hlau. Lub puas steel siv lead ua nyob rau hauv lub stamping txheej txheem tiag thiaj li sib nqus zoo tshaj ntawm cov cov ntim. Annealing flattens lub lamination thiab recrystallizes lub puas muaju thaum lub sij hawm stamping, yog li txuas rau ib daim ntawv thickness rau hauv lub lamination.
- Stator lamination los ntawm immersion txheej txheem
Impregnated stator txhawb qhov hluav taws xob rwb thaiv tsev ntawm stator winding, tiv thaiv tus ntawm cov tshuaj los yog hnyav ib puag ncig, thiab tej thaum tshav kub kub dissipation. Thermosetting yas nrog rau epoxy cob, phenolic cob thiab polyester yog siv los impregnate lub stator. Lub da dej txoj kev yog mus raus stator nyob rau hauv lub cob rau ib ntev lub sij hawm los xyuas kom meej qhov zoo tshaj plaws allergic thiab kev tiv thaiv. Lwm txoj kev impregnation, hu ua lub tshuab nqus tsev siab, siv ib tug tank uas yog thawj emptied thiab ces pa mus cuag allergic ntawm lub stator. Thaum kawg, cov cavitation yog muab rho tawm los ntawm cov hluav taws xob winding, uas pab txoj kev thermal conductivity ntawm lub winding.
Qhov zoo ntawm cov ntau yam slots yog los txo to reactance, txo hniav mem poob thiab txhim kho overload muaj peev xwm. Qhov tsis zoo ntawm ntau stator slots yog nce nqi, qhov hnyav, magnetization tam sim no, hlau poob, cov neeg pluag cua txias, kub sawv thiab efficiency yuav txo tau.
3.High zoo ntshiab txhuas rau rotor tuag casting
Lub Mekas rotor yuav maximize lub pib torque, txo tus neeg xyuas pib kuj thiab txhim kho lub efficiency. Feem ntau cov induction lub cev muaj zog rotors yog nas tawb tsim. Lawv yog cov yuav kav ntev, yooj yim nyob rau hauv cov qauv thiab cov uas tsis muaj nyob rau hauv nqe, tab sis lawv muaj tsis muaj starting torque. Tooj rotor pab txoj kev ua hauj lwm zoo, tiam sis nws yog ib qhov nyuaj thiab kim siv thiab ua.
4.the cua kis ntawm tus rotor thiab cov stator yog optimized
Cua kis yog lub radial kev ncua deb ntawm lub rotor thiab cov stator ntawm tus txheej txheem radial lub cev muaj zog. Nyob rau hauv thiaj li yuav txhim kho cov kev tsim efficiency, nws yog tsim nyog los tswj cov pom cua kis. Cov huab cua kis loj koom cov qauv siv los ntawm stator, rotor, lub cev muaj zog tsev nyob thiab cov kabmob. Tag nrho cov ntawm no yuav muaj feem xyuam rau lub meej kawm tuab si lug ntawm lub stator thiab rotor ncej.
5. enameled hlau
Ib tug magnet los yog enameled hlau yog ib tug electrolytic refined tooj liab los yog txhuas hlau uas tau raug siab annealed thiab coated nrog ib tug los yog ntau tshaj khaubncaws sab nraud povtseg ntawm rwb thaiv tsev. Piv txwv li, siv tej nrog ib tug tag nrho ntawm 12 khaubncaws sab nraud povtseg ntawm rwb thaiv tsev. Raug insulating films, nrog rau kev nce ntawm ntau yam kub, yog polyethylene, polyurethane, polyester thiab polyimide, nrog lub siab tshaj plaws kub ntawm 250 ° C. thicker lub los yog square magnet nyob ntawm tej yog qhwv nrog kub polyimide los yog iav fiber daim kab xev, ntau tooj liab yog siv , loj neeg xyuas pib tuav thiab conductors kom tus ntoo khaub lig-sectional cheeb tsam ntawm stator thiab rotor windings. Qhov no thiaj li tsis kam ntawm cov winding thiab tsis tshwm sim los ntawm qhov tam sim no. Tooj liab nyob rau hauv lub stator winding ntawm lub npaum lub cev muaj zog yog feem ntau 20% ntxiv.
