Electromagnetic coil 14550884 rau Volvo excavator

Kho qhov ntsuas kev ua haujlwm tseem ceeb

Qhov Performance index ntawm inductance kauj yog qhov loj ntawm inductance. Tsis tas li ntawd, feem ntau hais lus, cov hlau qhov txhab nrog inductance coil yeej ib txwm muaj qee yam tsis kam, uas feem ntau me me thiab tuaj yeem tsis quav ntsej. Txawm li cas los xij, thaum tam sim no ntws hauv qee lub voj voog loj heev, qhov kev tiv thaiv me me ntawm lub kauj tsis tuaj yeem tsis quav ntsej, vim tias qhov tam sim no loj yuav siv lub zog ntawm lub kauj, ua rau lub kauj kub kub los yog hlawv tawm, yog li qee zaum hluav taws xob. lub zog uas lub kauj tuaj yeem tiv taus yuav tsum xav txog.

Inductance

Lub inductance l sawv cev rau cov yam ntxwv ntawm lub kauj nws tus kheej, tsis hais txog qhov tam sim no. Tsuas yog tshwj xeeb inductance coil (xim-coded inductance), feem ntau inductance tsis yog cim tshwj xeeb ntawm lub kauj, tab sis cim nrog lub npe tshwj xeeb. Inductance, tseem hu ua tus kheej inductance coefficient, yog lub cev muaj nuj nqis qhia txog tus kheej inductance peev xwm ntawm inductor. Qhov inductance ntawm inductor feem ntau yog nyob ntawm tus naj npawb ntawm cov kauj, hom winding, muaj los yog tsis muaj cov tub ntxhais thiab cov khoom ntawm cov tub ntxhais, thiab lwm yam. Feem ntau, lub coil tig ntau dua thiab denser coils raug mob, ntau dua qhov inductance. Lub inductance ntawm lub coil nrog cov tub ntxhais sib nqus yog loj dua li ntawm lub kauj tsis muaj cov tub ntxhais sib nqus; Qhov ntau dua qhov sib nqus permeability ntawm cov tub ntxhais, qhov inductance ntau dua.

Lub hauv paus ntawm inductance yog Henry (Hen luv), uas yog sawv cev los ntawm tsab ntawv "H". Cov chav siv feem ntau yog milli-Heng (mH) thiab micro-Heng (μH), thiab kev sib raug zoo ntawm lawv yog:

1 H = 1000 mH

1 mH = 1000 mH

Inductive reactance

Qhov loj ntawm qhov tsis kam ntawm inductance coil rau AC tam sim no yog hu ua inductance XL, nrog ohm ua chav tsev thiab ω ua lub cim. Nws kev sib raug zoo nrog inductance L thiab AC zaus F yog XL = 2πfL.

Yam khoom zoo

Qhov zoo tshaj plaws Q yog lub cev muaj nuj nqis sawv cev rau lub kauj zoo, thiab Q yog qhov piv ntawm inductance XL rau nws qhov sib npaug, uas yog, Q = XL / R.. inductor ua haujlwm nyob rau hauv qee zaus AC voltage. Qhov siab dua Q tus nqi ntawm inductor, qhov tsawg dua qhov poob thiab qhov ua tau zoo dua. Q tus nqi ntawm cov kauj yog cuam tshuam nrog DC tsis kam ntawm tus neeg xyuas pib, qhov dielectric poob ntawm lub cev pob txha, qhov poob los ntawm cov ntaub thaiv npog lossis cov tub ntxhais hlau, kev cuam tshuam ntawm cov tawv nqaij ntau zaus thiab lwm yam. Q tus nqi ntawm lub kauj yog feem ntau kaum mus rau pua pua. Qhov zoo tshaj plaws ntawm cov inductor muaj feem xyuam rau DC tsis kam ntawm cov coil hlau, qhov dielectric poob ntawm lub kauj ncej thiab qhov poob los ntawm cov tub ntxhais thiab cov ntaub thaiv npog.
