Hauv induction lub cev muaj zog , plam yog tseem ceeb vim plam txiav txim siab lub zog thiab tseem ua haujlwm lub cav. Piav raws li hauv qab no: (1) Torque nyob ntawm lub zog fais fab uas, nyob rau hauv lem, nyob ntawm plam . Yog li, torque qis tshaj thaum plam (s) yog sib npaug rau 1 piv txwv li atstandstill.

Ntxiv mus, qhov tseem ceeb ntawm kev plam hauv 3 theem induction lub cev muaj zog yog dab tsi?

Nr < Ns, tus nqi ntawm plam s yog ib txwm tsawg dua ib. Rau induction lub cev muaj zog , 0 <tus <1. Thaum twg ib 3phase fais fab mov txuas nrog peb theem stator winding ntawm induction lub cev muaj zog , ib qho chaw sib nqus sib nqus tsim tawm hauv huab cua sib txawv. Qhov ceev ntawm qhov rotating magneticfield yog hu ua synchronous ceev.

Ib yam nkaus, vim li cas daim ntawv hla tebchaws yeej tsis xoom hauv lub cav induction? Hauv lub cav tus naj npawb ntawm rotor slots thiab statorslots txawv thiab yog li cogging (magnetic locking) tsis tuaj yeem tshwm sim. Thiab yog li ntawd swb lub cev muaj zog khiav tsis tau ntawm qhov ntsuas ceev. Torque tsim los ntawm induction lub cev muaj zog yog proportional rau cov plam . Ntawm synchronous ceev, plam yog xoom andhence torque tsim los ntawm lub cev muaj zog yog xoom.

Ib qho ntxiv, vim li cas lub tshuab hluav taws xob induction tseem ceeb?

Peb-theem nas-tawb induction motors yog siv dav raws li kev tsav tsheb vim tias lawv tau pib tus kheej, txhim khu kev qha thiab kev lag luam. Ib-theem induction motors tau siv dav rau qhov me me, xws li cov khoom siv hauv tsev zoo li cov kiv cua.

Dab tsi yog txhais los ntawm kev plam ntawm induction lub cev muaj zog?

plam ua tau txhais raws li qhov sib txawv nruab nrab ntawm qhov nrawm nrawm (Ns) thiab rotor nrawm (N). Ceev ntawm therotor ntawm ib induction lub cev muaj zog yog ib txwm tsawg dua nws cov synchronous ceev. Nws feem ntau yog qhia raws li feem pua ntawm synchronous ceev (Ns) thiab sawv cev los ntawm lub cim 'S'.
