Ugereranije na moteri ya DC na moteri idafite imbaraga, ibintu byingenzi biranga tekinike ya moteri ya Brushless DC ni:

1.Ibiranga imikorere ya moteri ya DC iboneka hakoreshejwe igenzura rya elegitoroniki.Ifite uburyo bwiza bwo kugenzura no kwaguka kwagutse.

2.Rotor imyanya yo gutanga ibitekerezo hamwe na elegitoroniki ya Multifase inverter ikenewe.

3.Byingenzi, moteri ya AC irashobora gukora kumuvuduko mwinshi nta spark na abrasion ya brush na commutator.Ifite ubwizerwe buhanitse, ubuzima burambye bwo gukora kandi ntibukeneye kubungabungwa.

4. Moteri ya DC idafite amashanyarazi ifite imbaraga nyinshi, nta gutakaza rotor nubushyuhe, hamwe nubushobozi buhanitse: ugereranije namakuru, imikorere ya moteri ya 7.5 kW itagira moteri ni 86.4%, kandi imikorere yubushobozi bumwe moteri ya DC idafite amashanyarazi irashobora kugera kuri 92.4% .

5.Hagomba kubaho ibice byo kugenzura ibikoresho bya elegitoronike, igiciro cyose kiri hejuru ya moteri ya DC.

Hariho ubwoko bubiri bwa moteri ikoreshwa muri sisitemu ya AC: moteri ya induction na moteri ihoraho ya moteri.Imashini ihoraho ya magnetiki irashobora kugabanywa inyuma ya sinusoidal inyuma ya EMF ihoraho ya magnetiki ihuza moteri (PMSM) hamwe na kwaduka kwaduka inyuma ya EMF brushless DC moteri (BLDCM) ukurikije amahame atandukanye yo gukora.Kugirango ibinyabiziga byabo bigezweho nuburyo bwo kugenzura biratandukanye.

Inyuma EMF ya sinusoidal ihoraho ya magnet synchronous moteri ni sinusoidal.Kugirango moteri itange urumuri rworoshye, umuyoboro unyura muri moteri igomba kuba sinusoidal.Kubwibyo, ibimenyetso bya rotor bihoraho bigomba kumenyekana, kandi inverter irashobora gutanga sinusoidal voltage cyangwa amashanyarazi kuri moteri.Kubwibyo, PMSM ikeneye gukoresha voltage nini cyangwa ikigezweho.Gukemura imyanya kodegisi cyangwa gukemura nabyo biragoye cyane.

BLDCM ntabwo ikeneye sensorisiyo yumwanya wo hejuru, igikoresho cyo gutanga ibitekerezo kiroroshye, kandi kugenzura algorithm biroroshye.Byongeye kandi, icyuho cyo mu kirere cya magnetiki yumurongo wa BLDCM trapezoidal ikora neza kuruta iy'umuhengeri wa PMSM sinusoidal, kandi ingufu za BLDCM ziri hejuru ya PMSM.Kubwibyo, gusaba no gukora ubushakashatsi bwa magnet burundu bidafite moteri ya DC yakiriye byinshi kandi byinshi.
