Kutheni le nto iimotor zeDC ezingenabrushless ezincinci kunye ne-micro brushed DC motors kulula kakhulu ukuzilawula?

Ekusetyenzisweni kwemoto,micro brushless DC motors&micro brushed DC motorskulula kakhulu ukulawula, kutheni kunjalo?

Xa kuthelekiswa neenjini ze-AC, iimotor ezincinci ze-DC kunye ne-micro DC brushed motors zinikwe amandla ngokuthe ngqo ngoku, njengeebhetri okanye i-AC/DC yokuguqula amandla.Iinjini ezincinci ze-DC ezingenasibhrashi&iinjini ezincinci ze-DC ezibrashwayoinokulawula isantya ngokuguqula ikhoyo ngoku kwi-winding ye-armature, ngelixa ii-motor ze-AC zifuna ii-frequency converters ukuze zitshintshe i-frequency.

Ulawulo lwesantya se-micro brushless DC motors & micro brushed DC motors inokuqondwa njenge torque yolawulo.I-torque yeemoto ezincinci ze-DC ezixutywayo kunye neenjini ezincinci ze-DC ezixutywayo zilingana nezangoku, ngoko ke utshintsho lwangoku kwi-armature yangoku luyakwazi ukulungelelanisa ngokufanelekileyo ulawulo lwesantya, kwaye umphumo ulungile kwaye ulula. , ngoko ke ukulawula imfuno yokuguqulwa rhoqo, oko kukuthi, ulawulo lwe-vector.

Ke ngoko, iimoto ezincinci ze-BLDC kunye neenjini ezincinci ze-DC ezibrashwayo zinokulawula isantya esingcono kunemoto ye-AC, kwaye indawo yemagnethi yemoto ye-DC inokulawula isantya ngokulawula i-excitation yangoku, elula kwaye efanelekileyo.
