Marka la barbar dhigo mashiinka DC-ga iyo matoorka asynchronous, sifooyinka farsamo ee muhiimka ah ee mashiinka DC-la'aanta waa:

1.The sifooyinka hawlgalka ee motor DC waxaa lagu helay by gacanta elektaroonik ah. Waxay leedahay xakamayn wanaagsan iyo xawli ballaaran.

2. Macluumaadka jawaab celinta booska Rotor iyo dareewalka inverter multiphase elegtarooniga ah ayaa loo baahan yahay.

3.Essentially, AC motor waxay ku shaqayn kartaa xawaare sare iyada oo aan dhimbiil iyo naaxinta burushka iyo commutator. Waxay leedahay kalsooni sare, nolol dheer oo shaqo ah oo aan u baahnayn dayactir.

4.Brushless DC motor wuxuu leeyahay awood sare, ma lumin rotor iyo kulaylka, iyo waxtarka sare: marka la barbardhigo xogta, waxtarka 7.5 kW asynchronous motor waa 86.4%, iyo waxtarka awoodda isku midka ah ee burushka DC waxay gaari kartaa 92.4% .

5.Waa in ay jiraan qaybo ka mid ah koontaroolka elektarooniga ah, wadarta kharashka ayaa ka sarreeya mashiinka DC.

Inta badan waxaa jira laba nooc oo matoorrada loo isticmaalo nidaamka AC: motor induction iyo motor synchronous magnet joogto ah. Matoorka isku midka ah ee magnet-ka joogtada ah waxaa loo qaybin karaa sinusoidal dhabarka EMF magnet joogto ah oo isku mid ah (PMSM) iyo mawjadaha labajibbaaran ee dhabarka EMF matoorka DC ee aan burushka lahayn (BLDCM) iyadoo loo eegayo mabda'a shaqo ee kala duwan. Si ay hadda iyo habka kontoroolkoodu u kala duwan yihiin.

Dhabarka EMF ee matoorka joogtada ah ee sinusoidal magnet synchronous waa sinusoidal. Matoorku si uu u soo saaro qulqulka siman, hadda socodka dhex socda matoorka waa inuu noqdaa sinusoidal. Sidaa darteed, calaamada booska rotor-ka joogtada ah waa in la ogaadaa, iyo inverter-ku wuxuu ku siin karaa koronto sinusoidal ama hadda matoorka. Sidaa darteed, PMSM wuxuu u baahan yahay inuu qaato danab sare ama hadda. Xallinta koodhka booska ama xaliye sidoo kale waa mid aad u adag.

BLDCM uma baahna dareemaha booska xallinta sare, aaladda jawaab celinta waa mid fudud, algoorithm-ka xakamaynta waa mid fudud. Intaa waxaa dheer, farqiga hawada ee magnetic field of BLDCM trapezoidal wave waa ka waxtar badan yahay kan PMSM sinusoidal wave, iyo cufnaanta awoodda BLDCM ayaa ka sarreeya kan PMSM. Sidaa darteed, codsiga iyo cilmi-baarista magnet-ka joogtada ah ee burushka DC-ka ayaa helay feejignaan iyo dheeraad ah.
