4. Raws li lub hom phiaj, lub cev muaj zog tuaj yeem muab faib ua: lub cev muaj zog rau kev tsav tsheb thiab lub cev muaj zog rau kev tswj.

 

5. Raws li cov qauv ntawm lub rotor: tawb induction lub cev muaj zog (qub qauv hu ua squirrel tawb induction motor) thiab lub qhov txhab rotor induction lub cev muaj zog (qub qauv hu ua lub qhov txhab asynchronous lub cev muaj zog).

 
6. Raws li kev ua haujlwm ceev, lawv tuaj yeem muab faib ua: cov motors siab ceev, cov motors qis, cov motors tsis tu ncua thiab ceev tswj cov motors. Tsawg-ceev motors tau muab faib ua iav motors, electromagnetic txo motors, torque motors thiab claw-pole synchronous motors.
 

二. Dab tsi yog lub tshuab hluav taws xob

 

Lub cev muaj zog hluav taws xob (Motor) yog ib qho khoom siv uas hloov hluav taws xob rau hauv lub zog siv tshuab. Nws yog kev siv cov energized coils (tseem hu ua stator windings) los tsim kom muaj qhov sib nqus sib nqus thiab ua haujlwm ntawm lub rotor (xws li squirrel tawb kaw aluminium thav duab) los tsim lub zog magnetoelectric rotating torque. Fais motors muab faib uaDC motorsthiab AC motors raws li lub zog siv. Feem ntau cov tshuab hluav taws xob hauv lub tshuab hluav taws xob yog AC motors, uas tuaj yeem ua synchronous lossis asynchronous (lub cev muaj zog stator magnetic teb ceev thiab rotor kev sib hloov ceev tsis tuav synchronous ceev). Lub tshuab hluav taws xob muaj feem ntau ntawm stator thiab rotor. Cov kev taw qhia ntawm kev txav ntawm ib qho hluav taws xob xaim hauv qhov chaw sib nqus yog cuam tshuam nrog cov kev taw qhia ntawm cov tam sim no thiab cov kev taw qhia ntawm cov kab sib nqus induction (magnetic field direction). Lub hauv paus ntsiab lus ua haujlwm ntawm lub cev muaj zog yog qhov sib nqus ua haujlwm raws li lub zog ntawm qhov tam sim no, ua rau lub cev muaj zog tig.

 

三 、 Cov qauv yooj yim ntawm hluav taws xob lub cev muaj zog

 

1. Cov qauv ntawm peb-theem asynchronous lub cev muaj zog muaj stator, rotor thiab lwm yam khoom siv.

 

2. DC lub cev muaj zog muaj octagonal, tag nrho cov qauv laminated nrog series excitation winding, uas yog tsim rau kev tswj tsis siv neeg thev naus laus zis qhov twg yuav tsum tau tig mus rau pem hauv ntej thiab rov qab. Lawv kuj tuaj yeem ua nrog series-zoo siab windings raws li cov neeg siv khoom xav tau. Lub cev muaj zog nrog qhov siab ntawm 100 txog 280 hli tsis muaj qhov nyiaj them rov qab, tab sis lub cev muaj zog nrog qhov siab ntawm 250 hli thiab 280 hli tuaj yeem ua nrog cov nyiaj them rov qab raws li cov xwm txheej tshwj xeeb thiab kev xav tau, thiab cov motors nrog qhov siab ntawm 315 txog 450 mm muaj kev them nyiaj winding. Qhov ntev thiab kev xav tau ntawm lub cev muaj zog nrog qhov nruab nrab qhov siab ntawm 500-710mm yog raws li IEC thoob ntiaj teb cov qauv, thiab cov neeg kho tshuab qhov ntev ntawm lub cev muaj zog yog ua raws li ISO thoob ntiaj teb cov qauv.

 

 

Puas muaj qhov sib txawv ntawm lub cev muaj zog thiab lub tshuab hluav taws xob?

 

Electric motors muaj xws li motors thiab generators. Nws yog ib lub ntsiab lus dav dav rau cov tshuab hluav taws xob thiab cov motors, thiab ob qho tib si yog qhov txawv ntawm qhov sib txawv. Lub tshuab hluav taws xob tsuas yog ib qho ntawm cov qauv kev ua haujlwm ntawm lub cev muaj zog, tab sis nws ua haujlwm hauv hom hluav taws xob, uas txhais tau hais tias lub zog hluav taws xob hloov mus rau lwm hom hluav taws xob; lwm hom kev ua haujlwm ntawm lub cev muaj zog yog lub tshuab hluav taws xob, uas ua haujlwm hauv lub zog tsim hluav taws xob, hloov lwm hom hluav taws xob rau hauv hluav taws xob hluav taws xob. Txawm li cas los xij, qee cov motors xws li synchronous motors feem ntau yog siv los ua cov tshuab hluav taws xob, tab sis kuj tuaj yeem siv ncaj qha li hluav taws xob motors. Asynchronous motors feem ntau yog siv los ua lub tshuab hluav taws xob, tab sis, nrog rau qhov sib ntxiv ntawm cov khoom siv hluav taws xob yooj yim, kuj tuaj yeem siv los ua cov tshuab hluav taws xob.
