Idan aka kwatanta da injin DC da injin asynchronous, mahimman halayen fasaha na injin Brushless DC sune:

1.The aiki halaye na DC motor samu ta lantarki iko. Yana da mafi kyawun sarrafawa da kewayon saurin gudu.

2.Rotor matsayi bayanin bayani da kuma lantarki multiphase inverter direba ake bukata.

3.Essentially, AC motor iya aiki a high gudun ba tare da walƙiya da abrasion na goga da commutator. Yana da babban abin dogaro, tsawon rayuwar aiki kuma baya buƙatar kulawa.

4.Brushless DC motor yana da babban iko factor, babu asarar rotor da zafi, da kuma babban inganci: idan aka kwatanta da bayanai, da inganci na 7.5 kW asynchronous motor ne 86.4%, da kuma yadda ya dace da wannan iya aiki brushless DC motor iya isa 92.4% .

5.There dole ne a lantarki iko sassa, jimlar kudin ne mafi girma fiye da DC mota.

Akwai galibi nau'ikan injina guda biyu da ake amfani da su a cikin tsarin AC: induction motor da injin maganadisu na dindindin. Motar da ke aiki tare da maganadisu na dindindin za a iya raba su zuwa sinusoidal baya EMF na dindindin magnet mai aiki tare (PMSM) da murabba'in kalaman baya EMF maras goge DC motor (BLDCM) bisa ga ka'idar aiki daban-daban. Don haka yanayin tuƙi da yanayin sarrafa su ya bambanta.

EMF na baya na sinusoidal magnet synchronous motor synchronous sinusoidal ne. Domin motar ta samar da karfin juyi mai santsi, yanayin da ke gudana ta cikin iskar motar dole ne ya zama sinusoidal. Sabili da haka, dole ne a san siginar matsayi mai ci gaba, kuma mai juyawa zai iya samar da wutar lantarki na sinusoidal ko halin yanzu zuwa motar. Don haka, PMSM yana buƙatar ɗaukar babban ƙarfin lantarki ko halin yanzu. Har ila yau ƙudurin mai rikodin matsayi ko mai warwarewa yana da rikitarwa sosai.

BLDCM baya buƙatar firikwensin matsayi mai tsayi, na'urar amsawa mai sauƙi ce, kuma algorithm mai sarrafawa yana da sauƙi. Bugu da kari, filin maganadisu na iska na BLDCM trapezoidal wave ya fi inganci fiye da na PMSM sinusoidal wave, kuma karfin karfin BLDCM ya fi na PMSM. Saboda haka, aikace-aikace da bincike na dindindin magnet brushless motor DC sun sami ƙarin kulawa.
