Na biyu, bambanci tsakanin AC servo motor da DC servo motor:
Motocin servo na DC sun kasu kashi-kashi zuwa injunan goge-goge da mara goge.Motocin da aka goge ba su da tsada, mai sauƙi a cikin tsari, babba a fara jujjuyawar wuta, faɗin kewayon tsarin saurin gudu, sauƙin sarrafawa, da buƙatar kulawa, amma suna da sauƙin kulawa (maye gurbin gogewar carbon), suna haifar da tsangwama na lantarki, kuma suna da buƙatu don muhalli.Sabili da haka, ana iya amfani dashi a cikin masana'antu na yau da kullun da na jama'a waɗanda ke kula da farashi.Motar da ba ta da goga tana da ƙananan girman, haske a nauyi, babban fitarwa, mai sauri a mayar da martani, mai girma a cikin sauri, ƙarami a cikin inertia, santsi a cikin juyawa da kwanciyar hankali.Gudanarwa yana da rikitarwa, kuma yana da sauƙin gane hankali.Hanyar tafiyar da wutar lantarkin sa mai sassauƙa ce, kuma tana iya zama motsi murabba'i ko motsin igiyar ruwa.Motar ba shi da kulawa, yana da babban inganci, ƙarancin zafin aiki, ƙarancin hasken lantarki, tsawon rai, kuma ana iya amfani dashi a wurare daban-daban.
Motocin AC servo sun kasu zuwa injina na aiki tare da asynchronous.A halin yanzu, gabaɗaya ana amfani da injunan aiki tare wajen sarrafa motsi.Ƙarfin wutar lantarki yana da girma kuma yana iya samun babban iko.Babban inertia, ƙananan matsakaicin saurin juyawa, kuma yana raguwa da sauri yayin da ƙarfin yana ƙaruwa.Saboda haka, ya dace da aikace-aikacen da ke gudana cikin sauƙi a ƙananan gudu.
