Aug 01, 2023

1, Cov qauv ntawm peb-theem asynchronous lub cev muaj zog muaj stator, rotor, thiab lwm yam khoom siv.
(1) Stator (qhov chaw nres tsheb)
1. Stator tub ntxhais
Muaj nuj nqi: Ib feem ntawm lub tshuab hluav taws xob sib nqus ntawm lub cev muaj zog, uas muab tso rau stator winding.
Kev tsim kho: Cov tub ntxhais stator feem ntau yog ua los ntawm 0.35-0.5 hli tuab silicon steel nplooj ntawv nrog cov txheej rwb thaiv tsev ntawm qhov chaw, xuas nrig ntaus thiab laminated, nrog cov qhov sib npaug sib npaug punched hauv lub voj voog sab hauv ntawm cov tub ntxhais. mus embed lub stator winding.
Muaj ntau ntau hom stator core groove hom:
Ib nrab kaw qhov: Qhov ua tau zoo thiab lub zog ntawm lub cev muaj zog yog qhov siab, tab sis cov winding embedding thiab rwb thaiv tsev yog qhov nyuaj. Feem ntau siv nyob rau hauv me me low-voltage motors. Ib nrab qhib qhov: Nws tuaj yeem kos nrog tsim windings thiab feem ntau yog siv rau cov motors loj thiab nruab nrab-tsawg-voltage motors. Lub thiaj li hu ua winding yog hais txog lub winding uas yuav tsum tau insulated ua ntej muab tso rau hauv lub qhov.
Qhib qhov: siv rau embedding tsim windings, nrog yooj yim rwb thaiv tsev txoj kev, mas siv nyob rau hauv high-voltage motors.
2. Stator winding
Function: Nws yog ib feem ntawm lub tshuab hluav taws xob uas siv peb-theem alternating tam sim no los ua kom muaj qhov sib nqus sib nqus.
Kev tsim kho: Nws yog tsim los ntawm peb qhov zoo tib yam windings teem nyob rau hauv ib tug symmetrical array nrog ib tug hluav taws xob lub kaum sab xis ntawm 120 degree sib nrug nyob rau hauv qhov chaw, thiab txhua kauj ntawm cov windings yog embedded nyob rau hauv txhua lub qhov ntawm lub stator raws li ib tug tej yam qauv.
Muaj peb yam tseem ceeb rwb thaiv tsev rau lub stator winding: (kom ntseeg tau tias muaj kev ruaj ntseg rwb thaiv tsev ntawm cov conductive qhov chaw ntawm lub winding thiab cov tub ntxhais hlau, nrog rau ntawm lub winding nws tus kheej).
1) Kev rwb thaiv tsev hauv av: Kev rwb thaiv tsev ntawm tag nrho stator winding thiab stator core.
2) Interphase rwb thaiv tsev: Qhov rwb thaiv tsev ntawm stator windings ntawm txhua theem.
3) Tig kom tig rwb thaiv tsev: Lub rwb thaiv tsev ntawm qhov lem ntawm txhua stator winding nyob rau hauv txhua theem.
Cov kab mob hauv lub cev muaj zog junction box:
Muaj ib lub rooj tsav xwm thaiv hauv lub thawv sib txuas lub cev muaj zog, qhov twg rau lub xaim terminals ntawm peb-theem winding yog teem rau hauv ob kab. Cov kab sab saud ntawm peb pawg kab txuas ntawm sab laug mus rau sab xis yog suav nrog 1 (U1), 2 (V1), 3 (W1), thiab cov kab qis ntawm peb kab thaiv kab teeb tsa los ntawm sab laug mus rau sab xis yog suav nrog 6 (W2), 4 (U2), thiab 5 (V2). Peb-theem winding txuas nrog lub hnub qub lossis daim duab peb sab. Txhua qhov kev tsim khoom thiab kev saib xyuas yuav tsum tau teem caij raws li tus lej xov tooj no.
3. Base
Muaj nuj nqi: Txhim kho lub stator core thiab pem hauv ntej thiab nram qab kawg npog los txhawb lub rotor, thiab muab kev tiv thaiv, tshav kub dissipation, thiab lwm yam dej num.
Kev tsim kho: Lub thav duab feem ntau yog ua los ntawm cov hlau cam, cov ncej ntawm cov asynchronous motors loj yog feem ntau welded nrog steel daim hlau, thiab cov ncej ntawm micro motors yog ua los ntawm cam khwb cia txhuas. Muaj cov cua kub dissipation ribs nyob rau sab nraud ntawm lub hauv paus lub cev muaj zog los ua kom lub tshav kub dissipation cheeb tsam, thiab lub qhov cua tau qhib rau ntawm qhov kawg npog ntawm kev tiv thaiv lub cev muaj zog ntawm ob hnub, tso cai ncaj qha convection ntawm huab cua sab hauv thiab sab nraud lub cev muaj zog los pab txhawb. kub dissipation.
(2) Rotor (rotating ib feem)
1. Lub rotor tub ntxhais ntawm peb-theem asynchronous lub cev muaj zog:
Muaj nuj nqi: Raws li ib feem ntawm lub cev muaj zog magnetic Circuit Court thiab tso lub rotor winding nyob rau hauv lub hlau core qhov.
Kev tsim kho: Cov khoom siv yog tib yam li cov stator, ua los ntawm 0.5 hli tuab silicon steel ntawv xuas nrig ntaus thiab laminated, nrog cov qhov sib npaug sib npaug punched rau ntawm lub voj voog sab nrauv ntawm silicon steel los xij kom haum rau rotor winding. Feem ntau, stator core yog siv los xuas nrig ntaus lub voj voog sab hauv ntawm cov ntawv lag luam silicon steel los ua cov rotor core. Feem ntau, lub rotor tub ntxhais ntawm me me asynchronous motors yog ncaj qha mus rau lub ncej, thaum lub rotor cores ntawm loj thiab nruab nrab asynchronous motors (nrog ib tug rotor txoj kab uas hla ntawm tshaj 300-400 millimeters) yog nias rau ntawm ncej nrog kev pab. ntawm lub rotor bracket.
2. Lub rotor winding ntawm peb-theem asynchronous lub cev muaj zog
Muaj nuj nqi: Txiav lub rotating magnetic teb ntawm lub stator generates induced electromotive quab yuam thiab tam sim no, thiab tsim electromagnetic torque ua rau lub cev muaj zog tig.
Kev tsim kho: muab faib ua squirrel tawb rotor thiab lub qhov txhab rotor.
1) Squirrel tawb rotor: Lub rotor winding yog tsim los ntawm ntau cov lus qhia tuav tso rau hauv lub rotor qhov thiab ob lub voj voog kawg. Yog hais tias lub rotor core raug tshem tawm, tag nrho cov winding yuav zoo li ib tug squirrel tawb, li no nws yog hu ua lub tawb winding. Lub tawb me me siv cov cam khwb cia txhuas rotor windings, thiab rau cov motors siab tshaj 100KW, lawv tau welded nrog tooj liab tuav thiab tooj liab kawg rings.
2) Qhov txhab rotor: Lub qhov txhab rotor winding zoo ib yam li stator winding thiab kuj yog ib qho kev sib tw peb-theem winding. Nws yog feem ntau txuas nrog lub hnub qub, thiab peb lub qhov hluav taws xob lub taub hau txuas nrog peb lub nplhaib sib sau ua ke ntawm cov ncej, thiab tom qab ntawd txuas rau sab nraud los ntawm kev txhuam hluav taws xob.
Cov yam ntxwv: Vim nws txoj kev ua qauv, daim ntawv thov ntawm lub qhov txhab hlau motors tsis yog qhov dav li ntawm squirrel tawb motors. Txawm li cas los xij, ntxiv cov resistors thiab lwm yam khoom siv txuas nrog hauv series los ntawm lub nplhaib sib sau thiab txhuam hauv rotor winding circuit los txhim kho qhov pib, braking, thiab kev tswj ceev ntawm asynchronous motors. Yog li ntawd, cov khoom siv uas yuav tsum tau muaj kev tswj hwm kev ceev ceev hauv ib qho chaw, xws li cranes, elevator, cua compressors, thiab lwm yam, yog siv.
(3) Lwm yam khoom siv rau peb-theem asynchronous motors
1. Xaus npog: txhawb kev ua haujlwm.
2. Bearings: Txuas cov rotating thiab chaw nres tsheb.
3. Bearing kawg npog: tiv thaiv cov kabmob.

2, DC lub cev muaj zog txais cov qauv octagonal tag nrho laminated, uas tsis tsuas yog muaj qhov chaw siv siab, tab sis kuj tuaj yeem tiv taus lub zog tam sim no thiab kev hloov pauv ceev ceev thaum siv los ntawm lub tshuab hluav taws xob zoo li qub. DC motors feem ntau tsis muaj series excitation windings thiab tsim nyog rau kev tswj tsis siv neeg thev naus laus zis uas yuav tsum tau tig rov qab thiab rov qab lub cev muaj zog. Raws li cov neeg siv xav tau, nws kuj tuaj yeem ua rau hauv kev ua kom muaj zog winding. Cov motors nrog qhov nruab nrab qhov siab ntawm 100-280mm tsis muaj qhov them nyiaj windings, tab sis cov motors nrog qhov siab nruab nrab ntawm 250mm lossis 280mm tuaj yeem ua nrog cov nyiaj them rov qab raws li cov xwm txheej tshwj xeeb thiab xav tau. Cov motors nrog qhov nruab nrab qhov siab ntawm 315-450mm muaj cov nyiaj them poob haujlwm. Tag nrho cov installation qhov ntev thiab cov kev xav tau ntawm lub cev muaj zog nrog qhov nruab nrab qhov siab ntawm 500-710mm ua raws li IEC thoob ntiaj teb cov qauv, thiab cov neeg kho tshuab qhov ntev ntawm lub cev muaj zog ua raws li ISO thoob ntiaj teb cov qauv.
