Juya shugabanci na motar BLDC

Kafin nutsewa cikin Farashin BLDC zaɓuɓɓukan amsawa, yana da mahimmanci don fahimtar dalilin da yasa kuke buƙatar su.BLDC Motors za a iya kaga don guda lokaci, biyu lokaci da uku lokaci; Mafi na kowa sanyi shi ne uku-phase.The yawan lokuta matches da yawan stator windings, yayin da yawan rotor Magnetic sandar iya zama kowane lamba dangane da aikace-aikace. Abubuwan da ake buƙata.Tun da rotor na motar BLDC yana da tasiri ta hanyar jujjuyawar igiyoyi masu juyawa, dole ne a bi diddigin matsayi na stator don fitar da matakan mota guda uku yadda ya kamata. Don wannan dalili, ana amfani da mai sarrafa motar don samar da yanayin motsa jiki na matakai shida akan. matakan mota guda uku.Wadannan matakai guda shida (ko commutators) suna motsa filin lantarki, wanda hakan ke haifar da magnet din rotor na dindindin don motsa mashin ɗin.
