Lub cev muaj zog DC brushless yog tsim los ntawm lub cev muaj zog thiab tus tsav tsheb, uas yog cov khoom siv mechatronics. Brushless lub cev muaj zog yog hais txog lub cev muaj zog uas tsis muaj txhuam thiab commutator (los yog lub nplhaib sau), tseem hu ua lub cev tsis muaj lub cev muaj zog. Raws li thaum ntxov xyoo pua kaum cuaj, thaum lub cev muaj zog tau yug los, lub cev muaj zog tsim tawm yog cov ntawv tsis txhuam, uas yog, AC squirrel tawb asynchronous lub cev muaj zog, uas tau siv dav. Txawm li cas los xij, asynchronous motors muaj ntau yam tsis tuaj yeem cuam tshuam rau kev txhim kho qeeb ntawm kev siv hluav taws xob. Nyob rau hauv nruab nrab ntawm lub xyoo pua xeem, transistors tau yug los, yog li brushless DC motors uas siv transistor commutation circuits es tsis txhob txhuam thiab commutators los ua. Qhov tshiab brushless lub cev muaj zog yog hu ua hluav taws xob commutated DC lub cev muaj zog, uas kov yeej qhov tsis txaus ntawm thawj tiam ntawm brushless motors.
