一, ubomi benkonzo: ubomi benkonzo yemoto ngaphandle kwekhabhoniibrashi isandoidla ngokulandelelana kwamashumi amawaka eeyure.Ubomi obuqhubekayo bokusebenza bemoto enesando se-carbon brush kumakhulu ukuya kwiiyure ezingaphezu kwewaka.Xa ifikelela kumda wokusetyenziswa, kufuneka ithathe indawo yebrashi yekhabhoni, ngaphandle koko kulula ukugqoka i-bearing, kwaye ubomi benkonzo abulunganga njengemoto ye-brushless.

二、 iindleko zokugcinwa: kukho isando sebrashi yekhabhoni idinga ukubuyisela ibrashi yekhabhoni, ukuba ukutshintshwa kuncinci kunokudala umonakalo kwimoto, kwaye akukho khabhoni.ibrashi isandoubomi benkonzo bude kakhulu, kodwa imfuneko eyaphukileyo yokutshintsha injini, kodwa ukugcinwa kwesiseko semihla ngemihla akufuneki.

三、 Ukulawulwa: akukho sando sebhrashi yekhabhoni ehlala ilawulwa yidijithali yokuguqulwa kwamaza, ngesando sebrashi yekhabhoni iqala ngokubanzi emva kokuba isantya sokusebenza singatshintshi.

Ulwazi olwandisiweyo

I-rotor ye-motor isebenza njengemagnethi ejikelezayo.Ukuba iibrashi zigqithise kakhulu, i-excitation current ayikwazi ukufikelela kwi-rotor, akukho ndawo yamagnetic ejikelezayo, ngoko ke ayikwazi ukusebenza ngokufanelekileyo.Ukungqubuzana komatshini kunye nombane omkhulu phakathi kwebrashi kunye nendandatho yomqokeleli ivelisa ubushushu obuninzi.Ngelo xesha, isixhobo somqokeleli sinqunyelwe yimeko ye-shafting kunye nemodi yokupholisa, kwaye imeko yokupholisa iyancipha.Ubushushu kwisixhobo somqokeleli weringi bugxininiswe kwaye ubushushu buphezulu.

I-Brushless DC motor yimveliso eqhelekileyo ye-mechatronics, eyenziwe ngumzimba wemoto kunye nomqhubi.Imagnethi esisigxina enemagnethi incamathele kwirotha yenjini.Ukuze ukhangele i-polarity ye-motor rotor, inzwa yendawo ifakwe kwi-motor.Umqhubi uqulunqwe izixhobo zombane zombane kunye neesekethe ezidibeneyo
