Saboda haka, yawancin labulen lantarki a kasuwa suna amfani da injin goge goge.
Hanyoyin Sarrafa Gudu daban-daban don Motocin Micro DC a Labulen Lantarki:
1. Lokacin daidaita saurin labulen lantarki na DC motor ta hanyar rage ƙarfin wutar lantarki, ana buƙatar samar da wutar lantarki na DC mai daidaitawa don kewayar armature. Ya kamata a rage juriya na da'irar armature da da'irar tashin hankali. Yayin da wutar lantarki ke raguwa, saurin labulen lantarki DC motor zai ragu daidai.
2. Gudanar da sauri ta hanyar gabatar da juriya na juriya a cikin da'irar armature na motar DC. Mafi girman juriya na jerin, mafi raunin halayen injina, kuma saurin rashin kwanciyar hankali. A ƙananan saurin gudu, saboda juriya mai mahimmanci, ƙarin makamashi ya ɓace, kuma ƙarfin wutar lantarki ya ragu. Matsakaicin sarrafa saurin yana tasiri ta hanyar kaya, ma'ana nau'ikan nau'ikan suna haifar da bambancin tasirin sarrafa saurin.
3. Rashin ƙarfi na saurin maganadisu. Don hana wuce kima jikewa na da'irar maganadisu a cikin labule na lantarki DC motor, sarrafa saurin ya kamata yayi amfani da maganadisu mai rauni maimakon ƙarfi magnetism. Wutar wutar lantarki na injin DC ɗin ana kiyaye shi akan ƙimar sa, kuma an rage girman juriya a cikin da'irar makaman. Ta hanyar haɓaka juriya na kewayawa Rf, tashin hankali na halin yanzu da motsi na maganadisu suna raguwa, ta haka ne ke haɓaka saurin labulen lantarki na injin DC da laushin halayen injina. Duk da haka, lokacin da saurin ya karu, idan jujjuyawar lodi ya kasance a ƙimar ƙima, ƙarfin motar na iya wuce ƙarfin da aka ƙididdige shi, ya sa motar ta yi aiki da yawa, wanda bai halatta ba.

Wannan ita ce hanyar sarrafa saurin wutar lantarki akai-akai. Don hana juzu'in na'urar rotor daga lalacewa da lalacewa saboda wuce gona da iri na ƙarfin centrifugal, yana da mahimmanci kada a wuce iyakar saurin da aka yarda da motar DC lokacin amfani da ikon sarrafa saurin filin maganadisu mai rauni.
4. A cikin tsarin kula da sauri na labulen lantarki na DC motor, hanya mafi sauƙi don cimma nasarar sarrafa sauri shine ta hanyar canza juriya a cikin kewayawa armature. Wannan hanya ita ce mafi sauƙi, mai tsada, kuma mai amfani don sarrafa saurin labulen lantarki.
Waɗannan su ne halaye da hanyoyin sarrafa saurin motocin DC waɗanda ake amfani da su a cikin labulen lantarki.
