Idan aka kwatanta da injin shigar da AC, injin DC mara goge yana da fa'idodi masu zuwa:

1. rotor rungumi dabi'ar maganadisu ba tare da m halin yanzu.Ikon wutar lantarki iri ɗaya na iya samun ƙarfin injina mafi girma.

2. rotor ba shi da asarar tagulla da asarar ƙarfe, kuma hawan zafin jiki ya fi karami.

3. lokacin farawa da toshewa yana da girma, wanda ke da amfani ga karfin gaggawa na gaggawa da ake buƙata don buɗewa da rufewa.

4. ƙarfin fitarwa na motar yana daidai da ƙarfin aiki da halin yanzu.Da'irar gano karfin juyi yana da sauƙi kuma abin dogara.

5. ta hanyar daidaita matsakaicin ƙimar ƙarfin wutar lantarki ta hanyar PWM, ana iya daidaita motar a hankali.Matsakaicin saurin da da'irar wutar lantarki abu ne mai sauƙi kuma abin dogaro, kuma farashin yana da ƙasa.

6. ta hanyar rage ƙarfin wutar lantarki da farawa motar ta PWM, ana iya rage lokacin farawa yadda ya kamata.

7. wutar lantarki na mota shine PWM modulation DC ƙarfin lantarki.Idan aka kwatanta da sine wave AC samar da wutar lantarki na AC m mitar motor, tsarin saurin sa da da'irar tuƙi yana haifar da ƙarancin hasken lantarki da ƙarancin gurɓataccen yanayi zuwa grid.

8. ta yin amfani da rufaffiyar madauki gudun kula da kewayawa, za a iya canza saurin motar lokacin da karfin juyi ya canza.
