Lokacin da motar ke aiki, man fetur da mai haɗawa suna juyawa, magnet da goga na carbon ba sa jujjuyawa, kuma canjin canjin yanayin halin yanzu yana cika ta hanyar commutator da goga wanda ke juyawa tare da motar. Motar da ba ta da gogewa tana ɗaukar motsi na lantarki, man fetur baya motsawa kuma igiyar maganadisu tana juyawa.
2. Bambancin yanayin ƙayyadaddun saurin gudu: A gaskiya ma, duka injinan ana sarrafa su ta hanyar ka'idodin wutar lantarki, kawai saboda brushless DC yana amfani da motsi na lantarki, ana buƙatar sarrafa dijital. Brushless DC ana canza shi da goga na carbon, kuma ana iya sarrafa shi ta hanyar da'irar analog na gargajiya kamar sarrafa silicon, wanda yake da sauƙi.
Bambance-bambancen aiki:
▶ 1. Motar goga tana da tsari mai sauƙi, tsawon lokacin haɓakawa da fasaha mai girma.
Tun farkon haifuwar mota a ƙarni na sha tara, injin ɗin da aka samar ba shi da buroshi, watau AC squirrel-cage asynchronous motor, wanda aka fi amfani dashi tun zamanin AC. Duk da haka, akwai lahani da yawa da ba za a iya jurewa ba a cikin motar asynchronous, ta yadda ci gaban fasahar motar ke tafiyar hawainiya.
▶ 2. Motar goga ta DC tana da saurin amsawa da kuma babban juzu'in farawa:
Motar goga ta DC tana da saurin farawa mai sauri, babban juzu'in farawa, canjin saurin sauri, kuma da kyar yana iya jin girgiza daga sifili zuwa matsakaicin gudun. Zai iya fitar da kaya mafi girma lokacin farawa. Motar da ba ta da gogewa tana da babban juriya na farawa (inductance), don haka yana da ƙaramin ƙarfin wuta, in mun gwada ƙarancin farawa, humming lokacin farawa, tare da rawar jiki mai ƙarfi, ƙaramin tuki lokacin farawa.
▶ 3. Motar goga ta DC tana aiki da kyau tare da sakamako mai kyau na farawa da birki:
Ana sarrafa injin goge goge ta hanyar wutar lantarki, don haka farawa da birki a hankali kuma suyi tafiya cikin sauƙi a koyaushe. Motoci marasa gogewa galibi ana sarrafa su ta hanyar jujjuyawar mitar dijital. Ana canza AC ta farko zuwa DC, sannan DC zuwa AC. Ana sarrafa saurin ta hanyar canjin mitoci. Don haka, injinan da ba su da buroshi suna gudana ba daidai ba lokacin farawa da birki, tare da babban rawar jiki, kuma kawai lokacin da saurin ya kasance akai-akai za su yi tafiya daidai.
▶ 4. Babban iko daidaito na DC goga motor:
Motar goga ta DC galibi ana amfani da ita tare da akwatin gear da dikodi, wanda ke sa ƙarfin fitarwar injin ya fi girma da daidaiton sarrafawa mafi girma. Daidaiton sarrafawa zai iya kaiwa 0.01 mm, kuma yana iya dakatar da sassa masu motsi kusan duk inda kuke so. Duk madaidaicin kayan aikin injin suna amfani da injin DC don sarrafa daidaito.
▶ 5. Motar goga na DC yana da ƙarancin farashi da sauƙin kulawa.
Saboda tsarin sa mai sauƙi, ƙarancin samarwa, masana'antun da yawa da fasahar balagagge, ana amfani da injin goga na DC sosai kuma ba shi da tsada sosai. Fasahar motar da ba ta da gogewa ba ta da girma, farashin yana da yawa kuma iyakar aikace-aikacen yana iyakance. Yakamata a yi amfani da shi musamman a cikin kayan aikin gaggawa akai-akai, kamar mitar kwandishan, firiji, da sauransu. Za a iya maye gurbin lalacewar mota mara goge kawai.
▶ 6. Tsangwama mara da gogewa:
Motar da ba ta da buroshi tana cire goge kuma mafi yawan canjin kai tsaye shine rashin tartsatsin wutar lantarki da aka samar a lokacin da injin ɗin ke gudana, wanda ke rage tsangwama da tartsatsin wutar lantarki akan kayan aikin rediyo na nesa.
