Kayan Kayan Wutar Lantarki na Asali IC LC898201TA-NH

taƙaitaccen bayanin:

LC898201 LSI ce mai sarrafa mota don kyamarorin sa ido waɗanda ke tafiyar da iris, zuƙowa, mai da hankali, da canza rana/dare.Yana haɗu da da'irori biyu na amsawa don iris da kulawar mayar da hankali, da da'irori masu sarrafa motsi guda biyu don zuƙowa da canza rana/dare.Hakanan, a ƙarƙashin zaɓin yanayi, ana amfani da sarrafa ra'ayi don sarrafa iris kuma ana amfani da sarrafa motar stepper don zuƙowa, mai da hankali, da canza rana/dare.

Direban mota shine mai canzawa, saboda abin da ke motsa motar yana da girma sosai ko kuma ƙarfin lantarki yana da girma sosai, kuma ba za a iya amfani da maɓalli na yau da kullun ko na'urorin lantarki a matsayin canji don sarrafa motar ba.

Matsayin Direban Motar: Matsayin direban motar yana nufin hanyar da za a iya samun ikon sarrafa saurin motar ta hanyar sarrafa kusurwar juyawa da saurin aiki na motar, ta yadda za a sami nasarar sarrafa tsarin aikin.

Siffar da'irar da'irar keɓaɓɓiyar keɓancewa ta Motoci: Za'a iya fitar da da'irar motar ko dai ta hanyar relay ko transistor, ko ta amfani da thyristor ko MOS FET mai ƙarfi.Don dacewa da buƙatun sarrafawa daban-daban (kamar aiki na yanzu da ƙarfin lantarki na motar, tsarin saurin injin, gaba da jujjuyawar injin DC, da sauransu), nau'ikan nau'ikan injin tuƙi dole ne su hadu da abubuwan da suka dace.
