Brushless vs Brushed Motors: Niki kibereye umushinga wawe?

Intangiriro

Ubwoko bubiri busanzwe bwa moteri ya DC ni moteri yogejwe hamwe na moteri idafite brush (moteri ya BLDC). Nkuko izina ribivuga, moteri yasunitswe ikoresha brush kugirango igabanye icyerekezo, ituma moteri izunguruka. Ibinyuranye, moteri ya Brushless isimbuza imikorere ya mikoranike yo kugenzura no kugenzura ibikoresho bya elegitoroniki. Ubwoko bwombi bukora ku ihame rimwe, arirwo rukurura rukuruzi hamwe no kwanga rukuruzi hagati ya coil na rukuruzi ihoraho. Buriwese afite ibyiza bye nibibi, bishobora guhindura amahitamo yawe ukurikije ibisabwa byihariye bya porogaramu yawe. Gusobanukirwa itandukaniro riri hagati ya moteri ya DC yasunitswe na moteri ya DC idafite amashanyarazi ningirakamaro mugusuzuma imikorere yabo. Icyemezo cyo guhitamo ubwoko bumwe kurenza ubundi bushingiye kubintu bitandukanye, harimo gukora neza, igihe cyo kubaho nigiciro.

Impamvu zingenzi zitandukanya moteri ya DC yasunitswe kandi idafite amashanyarazi:

# 1. Gukora neza

Moteri ya Brushless ikora neza kuruta moteri yasunitswe. Bahindura ingufu z'amashanyarazi ingufu za mashini hamwe nibisobanuro birambuye, bityo bikagabanya imyanda yingufu. Bitandukanye na moteri ya DC yasunitswe, moteri idafite brush ntishobora guhura cyangwa gutakaza ingufu zijyanye no guswera no kugenda. Ibi bitezimbere imikorere, byongerera igihe, kandi bigabanya gukoresha ingufu.

Ibinyuranye, moteri yogejwe ifatwa nkibidakorwa neza kuruta moteri ya DC idafite amashanyarazi kubera gutakaza ingufu zijyanye no guterana no guhererekanya ingufu binyuze muri sisitemu yo kugenda.

# 2. Kubungabunga no Kuramba

Brushless moterigira ibice byimuka kandi bikabura guhuza imashini, bikavamo kuramba no kugabanya ibisabwa byo kubungabunga. Kubura guswera bikuraho ibibazo bijyanye no kwambara brush nibindi bibazo byo kubungabunga. Kubwibyo, moteri idafite amashanyarazi akenshi iba ihendutse cyane kubakoresha.

Byongeye kandi, moteri yogejwe isaba kubungabungwa cyane kubera kwambara no kurira kuri brux na commutator, bishobora gutuma imikorere igabanuka nibibazo bya moteri. Kugirango ukomeze imikorere myiza, guswera bigomba gusimburwa buri gihe.

# 3. Urusaku no kunyeganyega

Muri moteri idafite amashanyarazi, umuyaga uhindagurika urashobora kugenzurwa, bifasha kugabanya impanuka ya torque ishobora gutera kunyeganyega n urusaku rwimashini. Kubwibyo, moteri idafite brush muri rusange itanga urusaku ruke no kunyeganyega kuruta moteri yasunitswe. kuberako badafite brush cyangwa abagenzi. Kugabanuka kwinyeganyeza n urusaku biteza imbere abakoresha kandi bigabanya kwambara no kurira hejuru yo gukoresha.

Muri moteri ya DC yasunitswe, brushes na commutator bikorana nkuburyo bwo guhinduranya. Iyo moteri ikora, izi switch zihora zifungura no gufunga. Iyi nzira ituma imigezi myinshi itembera muri rotor ya inductive rotor, ikabyara urusaku ruke rw'amashanyarazi kubera umuvuduko munini w'amazi.

# 4. Ikiguzi no kugorana

Moteri ya Brushless ikunda kuba ihenze kandi igoye kubera sisitemu yo kugenzura ibikoresho bya elegitoronike. Igiciro kiri hejuru ya moteri ya DC idafite brush ugereranijemoteri ya DCbiterwa ahanini na elegitoroniki yateye imbere igira uruhare mugushushanya kwabo.

# 5. Igishushanyo n'imikorere

Moteri ya Brushless DC ntabwo yikorera wenyine. Bakenera umuzunguruko ukoresha moteri ikoresha tristoriste kugirango igenzure umuyaga unyura mumashanyarazi. Moteri ikoresha igenzura rya elegitoronike hamwe na sensor ya Hall yingirakamaro kugirango icunge ibizunguruka, aho kwishingikiriza kumashanyarazi.

Moteri ya DC yamenetse irigendagenda, bivuze ko idasaba umuzunguruko wo gukora. Ahubwo, bakoresha imashini zogosha hamwe nabagenzi kugirango bagenzure imiyoboro ihindagurika, bityo barema umurima wa rukuruzi. Uyu murima wa magneti ukora urumuri, bigatuma moteri izunguruka.

# 6. Porogaramu

Nkigiciro cyamoteri yinyeganyezahamwe nibikoresho bya elegitoroniki bifitanye isano bikomeje kugabanuka, ibyifuzo bya moteri idafite amashanyarazi na moteri yogejwe biriyongera. Moteri ya Brushless irazwi cyane kumasaha yubwenge, ibikoresho byubuvuzi, ibikoresho byubwiza, robot, nibindi.

Ariko haracyari ahantu moteri zogejwe zumvikana cyane. Hariho porogaramu nini ya moteri yogejwe muri terefone zigendanwa, e-itabi, abagenzuzi b'imikino ya videwo, massage y'amaso, n'ibindi.
