Kev sib cais-theem ib-theem lub cev muaj zog siv lub capacitor lossis resistor txoj hlua los hloov cov theem ntawm inductive pib winding, kom cov theem tam sim no ntawm kev pib winding thiab kev ua haujlwm winding yog staggered, uas yog hu ua "theem sib cais" .
(1) Capacitor split-theem ib-theem lub cev muaj zog
Txij li cov theem hloov pauv ntawm lub capacitor yog qhov pom tseeb, tsuav yog lub capacitor nrog lub peev xwm tsim nyog (feem ntau yog li 20-50μF) txuas nrog hauv qhov pib winding, qhov tam sim no theem sib txawv ntawm ob lub windings tuaj yeem nyob ze rau 90 °, thiab qhov tshwm sim rotating magnetic teb yog ze rau Vim yog lub voj voog rotating magnetic teb, qhov pib torque loj thiab qhov pib tam sim no me me.Hom no ib-theem lub cev muaj zog yog dav siv, thiab nws tuaj yeem khaws cia (hu ua lub capacitor khiav lub cev muaj zog) lossis txiav tawm raws li xav tau tom qab pib (hu ua capacitor pib lub cev muaj zog, uas raug tua los ntawm kev hloov centrifugal tso rau hauv lub cev muaj zog).Yog tias koj xav tau hloov cov kev taw qhia ntawm kev sib hloov ntawm lub cev muaj zog, koj tsuas yog yuav tsum tau hloov lub qhov hluav taws xob kawg ntawm txhua qhov winding.Lub sijhawm no, theem tam sim no kev sib raug zoo ntawm ob lub windings yog opposite.
(2) Resistance split-phase ib-theem lub cev muaj zog
Hom lub cev muaj zog no muaj tsawg tus lem nyob rau hauv qhov pib winding thiab nyias hlau.Piv nrog rau kev khiav winding, lub reactance yog me me thiab qhov tsis kam yog loj.Thaum qhov kev sib cais-theem pib tau txais yuav, qhov pib winding tam sim no ua ntej ntawm kev khiav winding, thiab cov khoom sib nqus sib nqus yog ib qho elliptical rotating magnetic teb nrog loj ellipticity, thiab pib torque me me.Nws tsuas yog siv rau lub sijhawm tsis muaj load lossis lub teeb-load thiab muaj tsawg dua daim ntawv thov.Qhov pib winding ntawm qhov tsis kam sib cais-theem ib-theem lub cev muaj zog feem ntau yog tsim los rau kev ua haujlwm luv luv, thiab raug txiav tawm los ntawm kev hloov centrifugal tom qab pib, thiab kev ua haujlwm winding tswj kev ua haujlwm.
Shaded ncej ib-theem lub cev muaj zog
Ib feem ntawm cov stator sib nqus ncej yog embedded nyob rau hauv luv luv-circuit tooj liab rings los yog luv luv-circuit coils (paub pawg) los tsim ib tug ntxoov ntxoo-ncej ib-theem lub cev muaj zog.Shaded ncej ib-theem motors muaj ob hom: salient ncej thiab zais ncej.
