Yintoni umgaqo wokusebenza wemoto yeDC?

Isebenza njani i-dc motor?

I-DC motor ngumatshini oguqula amandla ombane abe ngamandla oomatshini ngendlela yokujikeleza. Intshukumo yawo iveliswa yindlela esebenza ngayo i-electromagnetism.Imoto yeDC zine-inductors ngaphakathi, ezivelisa i-magnetic field esetyenziselwa ukuvelisa intshukumo. Kodwa le magnetic field itshintsha njani ukuba kusetyenziswa i-DC current?  

I-electromagnet, eyintsimbi egqunywe nge-wire coil ene-voltage efakwe kwiiterminal zayo. Ukuba kongezwa iimagnethi ezimbini ezizinzileyo kumacala omabini ale electromagnet, amandla arhabaxa nanomtsalane aya kuvelisa i-torque.  

Emva koko, kukho iingxaki ezimbini ekufuneka zisonjululwe: ukondla umbane kwi-electromagnet ejikelezayo ngaphandle kokuba iingcingo zijijeke, kunye nokutshintsha indlela umbane ohamba ngayo ngexesha elifanelekileyo. Zombini ezi ngxaki zisonjululwa kusetyenziswa izixhobo ezibini: i-commutator eqhekezayo, kunye neebhrashi ezimbini.

Njengoko kunokubonwa, i-commutator ineziqendu ezibini ezidityaniswe kwisiphelo ngasinye se-electromagnet, ngaphandle kweentolo ezibini kukho iibhrashi ezisebenzisa umbane kwi-electromagnet ejikelezayo.imoto yokungcangcazelaIimoto zeDC zinokufumaneka kwiindawo ezintathu endaweni yeebhrashi ezimbini nezimbini.

Ngale ndlela, njengoko i-electromagnet ishukuma, i-polarity yayo iyatshintsha kwaye i-shaft ingaqhubeka ijikeleza. Nokuba kulula kwaye kuvakala ngathi iza kusebenza kakuhle, kukho imiba ethile eyenza la ma-motor angasebenzi kakuhle kwaye angazinzile, ingxaki ephambili ibangelwa lixesha phakathi kokuguqulwa kwe-polarity nganye. Ekubeni i-polarity kwi-electromagnet itshintshwa ngoomatshini, kwezinye ii-velocities i-polarity itshintsha ngokukhawuleza, nto leyo ebangela ii-reverse impulses kwaye ngamanye amaxesha itshintshe kade, ivelise "i-stop" ekhawulezileyo ekujikelezeni. Nokuba imeko injani na, ezi ngxaki zivelisa iincopho zangoku kunye nokungazinzi koomatshini.

Yasekwa ngo-2007, iLeader Microelectronics (Huizhou) Co., Ltd. lishishini lamazwe ngamazwe elidibanisa uR & D, imveliso kunye nokuthengisa. Sivelisa ikakhuluinjini ethe tyaba, imoto ethe tye,Imoto ye-BLDC, imoto engenasiseko, Imoto ye-SMD, Imoto yokubonisa umoya, Imoto yokunciphisa ubushushu njalo njalo, kunye nemoto encinci esetyenziswa kwiindawo ezininzi.
