Txoj kev txiav txim qhov zoo ntawm hluav taws xob motors nrog ib tug Multimeter
Muaj peb-theem motors thiab ib-theem motors, thiab ib-theem motors kuj muaj peb thiab rau cov xov hlau.
Peb-theem lub cev muaj zog
Rau kais rau peb-theem winding ntawm peb-theem lub cev muaj zog. Cia peb ua ntej tshem tawm qhov txuas txuas txuas ntawm lub tshuab hluav taws xob. Ntsuas qhov pib thiab qhov kawg ntawm txhua theem winding nrog lub multimeter kom pom tias nws yog nyob rau lossis tawm. Tom qab ntawd siv multimeter los ntsuas tus nqi tiv thaiv ntawm txhua ob theem winding cais, tsawg kawg ntau dua 0.5 megohms, qhov ntau dua qhov zoo dua. Thaum kawg, ntsuas qhov rwb thaiv tsev tiv thaiv ntawm txhua theem winding thiab lub cev muaj zog, uas yuav tsum tsis muaj qhov kawg. Los ntawm kev ntsuas nyob rau hauv txoj kev no, qhov zoo ntawm peb-theem lub cev muaj zog tuaj yeem raug txiav txim siab.
Peb xaim ib-theem lub cev muaj zog
Lub cev muaj zog unidirectional tsuas muaj ob lub windings, ib qho rau pib thiab ib qho rau kev khiav. Ib qho ntawm peb cov xov hlau yog lawv cov hlau sib xws, uas txhais tau hais tias ib qho kawg ntawm ob-theem winding txuas ua ke. Qhov thib ob yog lwm cov kais dej ntawm ob-theem winding.
Qhov kev tawm tsam ntawm ob lub kais dej yuav tsum yog qhov siab tshaj plaws thiab sib npaug ntawm qhov sib npaug ntawm qhov kev ua haujlwm ntawm ob lub windings.
Tau kawg, peb kuj yuav tsum ntsuas qhov kev tawm tsam ntawm lub kauj thiab lub casing kom pom tias nws tau tawg lawm. Qhov siab dua qhov tsis kam, qhov zoo dua, thiab qis tshaj yog tib yam, tsis tsawg dua 0.5 megaohms.
6-wire ib-theem lub cev muaj zog
Yog vim li cas vim li cas thiaj muaj 6 kab yog tias muaj ob kab (Z1, Z2) uas yog centrifugal hloov kab. Hom hluav taws xob no kuj muaj 6 terminals, yog li nws cov khoom sib txuas yuav tsum tau muab tshem tawm thiab. Tshem tawm lub capacitor ib yam nkaus, thiab tom qab ntawd ntsuas qhov ntsuas qhov tseem ceeb ntawm qhov pib thiab qhov kawg ntawm ob theem windings, nrog rau ntawm ob theem windings. Txoj kev yog tib yam li rau peb-theem motors.
Siv lub multimeter los txiav txim qhov zoo ntawm lub cev muaj zog tuaj yeem tsuas yog kev txiav txim ua ntej. Lub rwb thaiv tsev tiv thaiv ntawm windings thiab rwb thaiv tsev tsis kam ntawm txhua theem winding rau hauv av yuav tsum tau ntsuas nrog megohmmeter kom raug ntau dua.
Kuj tseem muaj qhov luv luv ntawm qhov kev sib hloov ntawm cov winding uas tsis tuaj yeem ntsuas, thiab peb tsuas yog siv cov kev sib piv los kwv yees seb puas muaj qhov tshwm sim ntawm kev sib tw luv luv. Piv txwv li, yog tias lub koom haum ntawm qee theem winding tsawg dua li ntawm ob theem, peb tuaj yeem xav tias nws muaj qhov cuam tshuam luv luv.
