Xa kuthelekiswa ne-AC induction motor, i-brushless DC motor inezibonelelo ezilandelayo:

1. I-rotor isebenzisa iimagnethi ngaphandle komsinga onomdla. Amandla ombane afanayo anokufikelela kumandla amakhulu oomatshini.

2. I-rotor ayinalahleko yobhedu kwaye ayinalahleko yentsimbi, kwaye ukunyuka kobushushu kuncinci nangakumbi.

3. Umzuzu wokuqala nowokuvala mkhulu, nto leyo eluncedo kwi-torque ekhawulezileyo efunekayo ekuvuleni nasekuvaleni ivalvu.

4. i-torque yokukhupha yemoto ihambelana ngqo ne-voltage yokusebenza kunye nomsinga. Isekethe yokufumanisa i-torque ilula kwaye ithembekile.

5. Ngokulungisa ixabiso eliphakathi levolthi yombane ngePWM, injini ingalungiswa kakuhle. Isekethe yamandla okulawula isantya kunye nokuqhuba ilula kwaye ithembekile, kwaye ixabiso liphantsi.

6. ngokunciphisa i-voltage yombane kunye nokuqalisa i-motor nge-PWM, umsinga wokuqala ungancitshiswa ngokufanelekileyo.

7. Umbane wemoto yi-PWM modulated DC voltage. Xa kuthelekiswa nombane we-sine wave AC wemoto ye-AC variable frequency, ukulawulwa kwesantya sayo kunye nesekethe yokuqhuba ivelisa imitha ye-electromagnetic encinci kunye nongcoliseko oluncinci lwe-harmonic kwigridi.

8. Ukusebenzisa isekethe yokulawula isantya esivaliweyo, isantya semoto sinokutshintshwa xa i-torque yomthwalo itshintsha.
