Sakamakon bincike don farawar da ba a saba ba na injin DC maras goge tare da ƙarfin waje

Bayan dababur DC motorAn nema na wani lokaci, abokin ciniki ya gano cewa motar tana farawa mara kyau, wani lokaci dole ne ya dogara da ƙarfin waje don farawa?
Akwai manyan dalilai guda uku:
1. Zaure maras al'ada, duba ko layin Hall
2. A duba ko farantin zaure ya cika da ruwa, domin muhallin yana da ruwa
3. Bincika ko an haɗa potentiometer na tuƙi.
Binciken farawar da ba a saba ba na injin DC mara gogewa tare da ƙarfin waje.

Hanyar gwaji:
Idan injin DC maras goge ya sami irin wannan matsala, yakamata mu haɗa wayar motar.Idan da goshin DCmota baya juyowa, sa'an nan da karfi a kan shaft ɗin motar.Idan injin DC mara goge ya juya, mafita shine mu ɗauki multimeter na dijital don bincika layin ɓangaren motar,
Da farko, kun sanya baƙar alkalami na multimeter na dijital akan H- na mai kula da motar DC maras goge, da kuma jan DC ammeter akan HV na mai sarrafawa.A wannan lokacin, kuna murƙushe mashin ɗin.A wannan lokacin, multimeter na dijital yana juya 0-9V, wanda ke nuna cewa komai na al'ada ne.
Har yanzu, mun sanya baƙar alkalami na multimeter na dijital akan H- na mai sarrafa motar DC maras gogewa, da kuma jan DC ammeter akan HV na mai sarrafawa a wannan lokacin don dunƙule kan mashin ɗin.A halin yanzu, multimeter na dijital shine jujjuyawar 0-9V, wanda ke nuna cewa komai na al'ada ne.

Alƙalamin baƙar fata na multimeter na dijital kuma akan H ɗin mu - a cikin mai sarrafa motar dc mara ƙarfi, jan dc ammeter cikin mai sarrafawa HW wannan lokacin don dunƙule kan mashin motar, lokacin koyaushe ya kasance 9 v ba tare da kunna multimeter na dijital ba, yana nuna cewa HW ba haka bane. mai kyau, a hankali HW hall element line, hall element line ba a haɗa da alaka da mota bayan wutar lantarki da aka juya.
