Hano hari inzira nkeya zo gutwara moteri ya DC idafite brush.Bimwe mubisabwa sisitemu yibanze kurutonde hepfo:
a.Imbaraga za tristoriste: Mubisanzwe ni MOSFETs na IGBTs zishobora guhangana na voltage nyinshi (bihuye nibisabwa na moteri).Ibikoresho byinshi byo murugo bikoresha moteri itanga ingufu za 3/8 (1HP = 734 W).Kubwibyo, bisanzwe bisanzwe bigezweho agaciro ni 10A.Sisitemu ya voltage nyinshi mubisanzwe (> 350 V) ikoresha IGBTs.
b.Umushoferi wa MOSFET / IGBT: Mubisanzwe, ni umushoferi witsinda rya MOSFET cyangwa IGBT.Nukuvuga, abashoferi batatu "igice-kiraro" cyangwa abashoferi b'ibyiciro bitatu barashobora gutoranywa.Ibi bisubizo bigomba kuba bishobora gukoresha ingufu za electromotive yinyuma (EMF) uhereye kuri moteri ikubye kabiri ingufu za moteri.Byongeye kandi, aba bashoferi bagomba gutanga uburinzi bwimbaraga za tristoriste binyuze mugihe no kugenzura ibintu, bakemeza ko transistor yo hejuru yazimye mbere yuko transistor yo hepfo ifunguye.
c.Ibitekerezo / kugenzura: Ba injeniyeri bagomba gushushanya ubwoko bwibitekerezo muri sisitemu yo kugenzura servo.Ingero zirimo ibyuma bya optique, ibyuma byerekana ibyumba bya salle, tachometero, hamwe nigiciro gito cyo kutumva inyuma EMF sensing.Uburyo butandukanye bwo gutanga ibitekerezo ni ingirakamaro cyane, bitewe nukuri gusabwa, umuvuduko, torque.Porogaramu nyinshi zabaguzi zishaka gukoresha inyuma ya tekinoroji ya EMF.
d.Guhindura Analog-to-Digital: Mubihe byinshi, kugirango uhindure ibimenyetso bisa kubimenyetso bya digitale, hagomba gutegurwa analog-to-digitale, ishobora kohereza ibimenyetso bya sisitemu muri sisitemu ya microcontroller.
e.Microcomputer imwe-chip: Sisitemu zose zifunze-zifunga (hafi ya moteri zose za DC zitagira brush zifunga sisitemu yo kugenzura) bisaba microcomputer imwe imwe, ishinzwe kubara servo loop igenzura, kugenzura PID kugenzura no gucunga sensor.Ubugenzuzi bwa digitale mubusanzwe ni 16-bit, ariko porogaramu zigoye zirashobora gukoresha 8-biti.
Imbaraga Zisa / Igenzura / Reba.Usibye ibice byavuzwe haruguru, sisitemu nyinshi zirimo ibikoresho byamashanyarazi, kugenzura ingufu za voltage, guhinduranya voltage, nibindi bikoresho bisa nka monitor, LDOs, DC-to-DC ihindura, hamwe na amplifier ikora.
Analog Power Supplies / Regulators / References: Usibye ibice byavuzwe haruguru, sisitemu nyinshi zirimo ibikoresho byamashanyarazi, imiyoboro ya voltage, imashini ihindura voltage, nibindi bikoresho bisa nka monitor, LDOs, DC-to-DC ihindura, hamwe na amplifier ikora.
