Brushless DC motors yog dav siv nyob rau hauv ntau yam kev siv, nrog rau cov khoom siv, khoom siv kho mob, thiab cov khoom siv hluav taws xob. Ib qho tseem ceeb ntawm cov motors no yog cov sib nqus txhaj tshuaj magnetic rotor, uas yog siv los muab kev ua tau zoo thiab txhim khu kev qha.
Ua los ntawm NdFeB hmoov thiab muaj kev ua tau zoo polymer binder, cov sib nqus txhaj tshuaj magnetic rotor yog cov hlau nplaum ua haujlwm siab uas muaj cov khoom sib nqus tshwj xeeb thiab ruaj khov. Lub rotor yog txhaj molded nrog cov hlau nplaum nyob rau hauv qhov chaw, ua rau muaj zog, compact, thiab tsim tau zoo.
