Nrog rau kev ua haujlwm tas mus li ntawm lub cev muaj zog, kaw-qhov rotors maj mam lees paub los ntawm cov tuam txhab tsav tsheb. Raupeb-theem asynchronous motors, vim muaj cov stator thiab rotor grooves, qhov kev sib hloov yuav ua rau cov pulsation poob. Yog hais tias lub rotor txais yuav kaw qhov, qhov zoo ntawm huab cua sib txawv yog luv, thiab lub pulsation ntawm cov pa sib nqus magnetic teb tsis muaj zog, yog li txo qhov excitation muaj peev xwm thiab harmonic magnetic teb poob, uas yuav pab txhim kho kev ua tau zoo ntawm lub cev muaj zog.
Arch kev taw qhia yog ib qho tseem ceeb parameter ntawm lub kaw qhov rotor, nyob rau hauv cov ntaub ntawv ntawm tib rotor slot hom, kev xaiv ntawm txawv choj koov qhov siab yuav muaj ntau yam kev cuam tshuam rau lub cev muaj zog kev ua tau zoo. Kaw qhov rotor stacking vim tsis muaj qhov tsis pom, kev kuaj xyuas kom zoo yog qhov nyuaj, yooj yim kom pom qhov teeb meem zais sawtooth, ua rau kom tsis txhob muaj teeb meem.
Kev siv ntawmrotor kaw qhovThaum txo qis kev poob thiab kev siv hlau ntawm lub cev muaj zog, yuav ua rau kom lub rotor to reactance, ua rau txo qis zog, nce stator load tam sim no, nce stator poob; pib torque thiab pib tam sim no poob, tus nqi turnover nce. Yog li ntawd, thaum siv qhov kaw, qhov kev hloov pauv ntawm ntau yam ntaub ntawv kev ua tau zoo yuav tsum tau txiav txim siab ib txhij los ua kom zoo dua qhov kev ua tau zoo ntawm lub cev muaj zog.
Dab tsi yog induction motor?
Induction lub cev muaj zog yog hais txog ib yam ntawm stator thiab rotor los ntawm electromagnetic induction, inductance tam sim no nyob rau hauv lub rotor kom paub electromechanical zog hloov lub cev muaj zog. Lub stator ntawm lub cev muaj zog induction muaj peb ntu: stator core, stator winding thiab lub rooj zaum. Lub rotor muaj cov tub ntxhais rotor, rotor winding thiab rotor ncej. Lub rotor tub ntxhais, uas kuj yog ib feem ntawm lub ntsiab sib nqus Circuit Court, feem ntau yog ua los ntawm silicon steel los xij stacked ntawm ib tug tuab ntawm 0.5 hli, thiab cov tub ntxhais yog tsau nyob rau hauv lub rotor ncej los yog rotor bracket. Tag nrho cov rotor muaj ib tug cylindrical tsos.
Covrotor windingstau muab faib ua ob hom: tawb thiab wirewound. Raws li ib txwm muaj, lub rotor ceev ntawm lub induction lub cev muaj zog yog ib txwm qis dua los yog siab dua qhov ceev ntawm lub rotating magnetic teb (synchronous ceev), yog li induction motors kuj hu ua "asynchronous motors". Thaum lub load ntawm lub induction lub cev muaj zog hloov, lub rotor ceev thiab qhov sib txawv ntawm qhov sib txawv yuav hloov raws li, yog li ntawd lub zog hluav taws xob, tam sim no thiab electromagnetic torque nyob rau hauv lub rotor conductor yuav hloov raws li cov kev xav tau ntawm lub load. Raws li qhov zoo lossis qhov tsis zoo ntawm kev sib hloov thiab qhov loj ntawm lub induction lub cev muaj zog, muaj peb hom kev ua haujlwm: lub cev muaj zog, lub tshuab hluav taws xob thiab hluav taws xob nres.
