Txoj kev txiav txim rau pem hauv ntej winding thiab rewinding nrog multimeter
Txhawm rau kho lub rotor winding, nws tsis tuaj yeem pom nrog lub qhov muag liab qab seb lub taub hau ntawm ib qho khoom yog twisted ntawm sab laug lossis sab xis. Nws yuav tsum raug txiav txim los ntawm kev ntsuas qhov tsis kam nrog cov ntaub ntawv multimeter R × 1Ω tsis kam. Txoj kev ua haujlwm tshwj xeeb yog raws li hauv qab no:
Nrhiav qhov kawg inlaid kauj nrog lub qhov muag liab qab (qhov kos npe yog tias ob qhov kawg ntawm lub kauj no tsis raug nias los ntawm lwm cov coils). Muaj ob lub coils rau ob chav winding, thiab tsuas yog ib qho xws li coil (nto keeb) rau overlapping winding.
Siv cov riam phom los txhuam tawm cov txheej txheej insulating ntawm nruab nrab ntawm qhov kawg ntawm cov khoom saum npoo no, thiab thaj tsam kom khawb tawm ntawm daim tawv nqaij insulating yog me ntsis loj dua.
Tig lub multimeter mus rau qib R × 1Ω tsis kam, ib qho kev xeem cov hlau lead yog nyob rau hauv kev sib cuag zoo nrog cov txheej txheem rwb thaiv tsev, thiab lwm yam kev xeem cov hlau lead yog nyob rau hauv kev sib cuag nrog lub commutator piece sib xws rau txoj cai qhov ntawm cov khoom (cov commutator piece sib raug rau kab nruab nrab ntawm lub qhov yog sab laug mus rau sab xis Txhua 3 daim), qhov tsawg kawg nkaus kuj yuav ntsuas. Tom qab ntawd nyob rau hauv commutator ntu sib txuas mus rau sab xis ntawm cov khoom siv (qhov sib txuas ntawm cov kab nruab nrab ntawm lub qhov yog nyob rau hauv 3 daim rau sab laug lossis sab xis), thiab qhov tsawg kawg nkaus kuj tseem yuav ntsuas. Muab piv rau ob qhov kev ntsuas qhov tseem ceeb, txoj hauj lwm uas qhov tsawg tshaj plaws cov hlau lead yog muab tso rau (ze ntawm sab xis los yog sab laug qhov) yog qhov twisted txoj hauj lwm ntawm lub caij. Yog hais tias tus twist yog twisted rau sab laug thais, lub pem hauv ntej winding yog siv; Yog hais tias tus twist yog twisted mus rau txoj cai notch, rov qab winding yog siv.
Thaum embedding cov khoom tshiab, nws yuav tsum tau de-embedded raws li qhov yuav tsum tau ntawm forward winding los yog rov qab winding.
【Kev paub me me】
Tom qab kev ntsuas, nws yog qhov zoo tshaj los nrhiav lwm yam khoom thiab ntsuas nws dua raws li cov qauv saum toj no. Cov txiaj ntsig ntawm ob lub sij hawm zoo ib yam, qhia tias qhov kev txiav txim yog qhov tseeb.
Thaum lub sij hawm qhov kev xeem, thaum lub Cheebtsam nyob rau saum npoo tsis muaj tus nqi kuj ob zaug los yog qhov luaj li cas yuav tsis muab piv, lwm yam yuav tsum tau nrhiav rau kev ntsuas. Thaum cov khoom ntawm qhov chaw tsis ntsuas, lwm yam khoom siv kuj tuaj yeem siv los ntsuas.
Thaum qhov kawg ntawm cov khoom nyob rau hauv kev sim scrapes tawm ntawm insulating txheej nrog ib tug wallpaper riam, nws yuav tsum tau scraped nyob qhov twg, tab sis lub scraped cheeb tsam yuav tsum tsis txhob me me heev. Qhov chaw yuav khawb yuav tsum yog hlau enamel ntau dua. Thaum tus cwj mem multimeter kov qhov hloov pauv, txhawm rau ntsuas kom raug ntau dua, nws yog qhov zoo tshaj los tso tus cwj mem ntsuas kab rov tav thiab sib cuag nrog qhov hloov pauv ntau li ntau tau.
