Ugereranyije na moteri ya DC na moteri idahuza, ibiranga tekiniki by'ingenzi bya moteri ya Brushless DC ni ibi bikurikira:

1. Imiterere y'imikorere ya moteri ya DC iboneka hakoreshejwe uburyo bw'ikoranabuhanga. Ifite ubushobozi bwo kugenzura neza no gukoresha umuvuduko mugari.

2. Amakuru yerekeye uko rota ihagaze n'umushoferi wa inverter w'ikoranabuhanga mu byiciro byinshi arakenewe.

3.Mu by'ukuri, moteri ya AC ishobora gukora ku muvuduko wo hejuru nta burashi cyangwa gushwanyagurika kw'uburoso na commutator. Ifite icyizere cyo hejuru, imara igihe kirekire kandi nta mpamvu yo kuyibungabunga.

4. Moteri ya DC idafite uburoso ifite imbaraga nyinshi, nta gihombo cya rotor n'ubushyuhe, kandi ifite imikorere myiza cyane: ugereranije n'amakuru, imikorere myiza ya moteri idafite uburoso ya 7.5 kW ni 86.4%, kandi imikorere myiza ya moteri ya DC idafite uburoso ishobora kugera kuri 92.4%.

5.Hagomba kuba hari ibice by'ikoranabuhanga bigenzura, igiciro cyose kiri hejuru y'icya moteri ya DC.

Hari ubwoko bubiri bwa moteri zikoreshwa muri sisitemu ya AC: moteri y’induction na moteri ihoraho ihuza magnet. Moteri ihoraho ihuza magnet ishobora kugabanywamo moteri ihuza magnet ihoraho ihuza magnet (PMSM) na moteri idafite brushless DC ihuza magnet (BLDCM) hakurikijwe amahame atandukanye y’imikorere. Ku buryo uburyo bwo kuyitwara n’uburyo bwo kuyigenzura bitandukanye.

EMF y'inyuma ya moteri ya sinusoidal ihoraho ifite magnetike ihoraho ni sinusoidal. Kugira ngo moteri ikore torque yoroshye, umuyoboro unyura muri moteri ugomba kuba sinusoidal. Kubwibyo, ikimenyetso cy'aho rotor ihagaze kigomba kumenyekana, kandi inverter ishobora gutanga voltage cyangwa amashanyarazi kuri moteri. Kubwibyo, PMSM igomba gukoresha voltage cyangwa amashanyarazi menshi. Uburyo bwo gusubiza imiterere y'aho iherereye cyangwa resolver nabwo buragoye cyane.

BLDCM ntabwo ikeneye sensor ifite ubushobozi bwo kugenzura ahantu hakomeye, igikoresho cyo gutanga ibitekerezo ni cyoroshye, kandi uburyo bwo kugenzura bworoshye. Byongeye kandi, imbaraga za rukuruzi z'ikirere za BLDCM trapezoidal wave zikora neza kurusha iz'umuraba wa PMSM sinusoidal, kandi ubucucike bwa BLDCM buri hejuru y'ubwa PMSM. Kubwibyo, ikoreshwa n'ubushakashatsi kuri moteri ya DC idafite brushless magnet ihoraho byarushijeho kwitabwaho.
