Mu myaka myinshi twamaze dutanga moteri nto za DC ku bakiriya b'imodoka, abaganga, n'ibikoresho by'ikoranabuhanga, twakusanyije ibibazo bikunze kubazwa. Dore ibibazo bitanu bya mbere, hamwe n'ibisubizo bifatika bivuye mu itsinda ryacu ry'abahanga mu ruganda.

Q1: Moteri yanjye irimo urusaku rwinshi kurusha uko byari byitezwe – ni iki gishobora kuba kitagenda neza?

Urusaku rukunze kuva ku masoko ya mekanike cyangwa amashanyarazi. Imekanike: reba niba vis zo gushyiraho ari ndende cyane, bigatuma imbere zikora, cyangwa niba shaft coupling idahuye neza. Ibyuma bikoresha amashanyarazi: moteri zikozwe muri brush zitanga urusaku rwinshi; kongeramo capacitor ya ceramic (0.1µF) ku miyoboro bishobora kuyigabanya. Kugira ngo uvuge cyane, hindura ukoreshe BLDC cyangwa moteri idafite core.

Q2: Moteri itangira idakora neza cyangwa igahagarara iyo umutwaro wayo woroshye.

Akenshi ibi biba ari ukugabanuka kwa voltage cyangwa torque idahagije yo gutangira. Pima voltage ku miyoboro ya moteri - insinga ndende zoroshye zishobora gutera kugabanuka gukomeye. Nanone, moteri nto zikenera starting current iri hejuru kurusha power ikora. Menya neza ko umuriro wawe ushobora gutanga nibura inshuro ebyiri z'amashanyarazi ya stall mu masegonda make. Niba ikibazo kigihari, gerageza moteri ifite torque iri hejuru cyangwa igipimo gito cya gear.

Q3: Ni gute narinda moteri ibibazo bya EMC/EMI?

Moteri zikoresha brush zizwiho imyuka ihumanya ikirere ituruka ku mirasire n'ibyuka biva mu kirere.

Capacitors zo gusoda (ubusanzwe 0.1µF + 0.01µF) kuva kuri buri gice cy'inyuma kugera ku gasanduku.

Koresha insinga zigoramye n'agasaro ka ferrite hafi ya moteri.

Kugira ngo habeho kubahiriza amategeko cyane (urugero, ubuvuzi cyangwa imodoka), tekereza kuri moteri ya BLDC - imikorere yayo y'ikoranabuhanga igabanya cyane ingaruka mbi.

Q4: Ubushyuhe bw'imikorere bufite umutekano ni ubuhe?

Moteri nyinshi za micro DC zikoresha insulation yo mu bwoko bwa E (120°C) cyangwa class B (130°C). Ubushyuhe bw'ikirere hamwe n'ubushyuhe bwite bigomba kuguma munsi y'uyu mupaka. Nk'uko bisanzwe, agasanduku ka moteri ntigakwiye kurenga 85°C kuri moteri zishushanyije, cyangwa 100°C kuri BLDC. Ubushyuhe bwinshi bwangiza magnets n'amavuta. Ku bidukikije bishyushye (urugero: ibice bya moteri), saba magnets n'amavuta y'ubushyuhe bwinshi.

Q5: Ni gute nakongera igihe cy'imikorere y'imodoka mu gihe idasiba?

Ubuzima bugarukira ku kwangirika k'uburoso (moteri zishushanyije) cyangwa kwangirika kw'amapine (moteri zose). Kugira ngo wongere ubuzima:

Koresha ingufu nke zishoboka zijyanye n'umuvuduko/torque yawe - ubushyuhe buke, uburoso buke.

Irinde gutangira/guhagarara kenshi - buri gutangira bitera brush current nyinshi.

Bika umukungugu n'ubushuhe mu nzu – koresha agakingirizo gafite agaciro ka IP cyangwa ongeramo agakingirizo k'umugozi.

Ku bijyanye n'amasaha 24/7, hindura ukoreshe moteri ya BLDC - igihe cyo gukoresha uburoso ntabwo kikiri imbogamizi.
