1. Umahluko womgaqo: i-brush motor ithatha ukuguqulwa komatshini, i-pole magnetic ayishukumi, i-cfuel iyajikeleza. Xa i-motor isebenza, i-cfuel kunye ne-commutator iyajikeleza, i-magnet kunye ne-carbon brush ayijikelezi, kwaye utshintsho olutshintshisayo lwe-cfuel lwangoku lufezekiswa ngumhambisi kunye ne-brush ejikelezayo kunye ne-motor. I-Brushless motor ithatha i-electronic commutation, i-cfuel ayishukumi kwaye i-pole magnetic ijikeleza.
2. Umahluko wendlela yokulawula isantya: Enyanisweni, zombini iimoto zilawulwa yi-voltage regulation, kuphela ngenxa yokuba i-brushless DC isebenzisa i-electronic commutation, ulawulo lwedijithali luyafuneka. I-Brushless DC iguqulelwa ngebrashi yekhabhoni, kwaye inokulawulwa ziisekethe ze-analog zemveli ezifana ne-silicon elawulwayo, elula kakhulu.
Umahluko ekusebenzeni:
▶ 1. Ibhrashi yemoto inesakhiwo esilula, ixesha elide lophuhliso kunye neteknoloji ekhulileyo.
Kwangoko ukuzalwa kwemoto ngenkulungwane yeshumi elinesithoba, imotor esebenzayo yaveliswa yayiyi-brushless form, okt i-AC squirrel-cage asynchronous motor, esetyenziswe ngokubanzi ukusukela kwisizukulwana se-AC. Nangona kunjalo, zininzi iziphene ezingenakugqithiswa kwi-asynchronous motor, ukwenzela ukuba uphuhliso lobuchwepheshe beemoto lucotha.
▶ 2. Injini yebrashi yeDC inesantya sokuphendula esikhawulezayo kunye netorque enkulu yokuqalisa:
Imoto yebrashi yeDC inempendulo ekhawulezayo yokuqalisa, itorque enkulu yokuqalisa, isantya esigudileyo sokutshintsha, kwaye ayiva lula ukungcangcazela ukusuka ku-zero ukuya kwisantya esiphezulu. Iyakwazi ukuqhuba umthwalo omkhulu xa iqala. I-Brushless motor inoxhathiso olukhulu lokuqalisa (i-inductance), ngoko ke inamandla amancinci, i-torque encinci yokuqala, iyancwina xa iqala, ihamba kunye nokungcangcazela okunamandla, umthwalo omncinci wokuqhuba xa uqala.
▶ 3. Injini yebrashi yeDC ibaleka kakuhle inesiqalo esihle kunye nesiphumo sokuqhobosha:
Iinjini zebhrashi zilawulwa ngamandla ombane, ngoko ke qala kwaye ubhuleke kakuhle kwaye ubaleke kakuhle ngesantya esingaguqukiyo. Iinjini zebrushless zihlala zilawulwa yidijithali yokuguqulwa kwamaza. I-AC yokuqala iguqulwa ibe yi-DC, emva koko i-DC ibe yi-AC. Isantya silawulwa ngokutshintsha rhoqo. Ke ngoko, ii-motor ezi-brushless zibaleka ngokungafaniyo xa ziqala kunye ne-braking, kunye ne-vibration enkulu, kwaye kuphela xa isantya sihlala sihlala siya kuhamba kakuhle.
▶ 4. Ulawulo oluchanekileyo lwemoto ye-DC brush:
Imoto yebrashi yeDC ihlala isetyenziswa kunye nebhokisi yegiya kunye ne-decoder, eyenza amandla okukhutshwa kwemoto abe makhulu kunye nolawulo oluchanekileyo. Ukuchaneka kokulawula kunokufikelela kwi-0.01 mm, kwaye kunokuyeka ukuhambisa iinxalenye phantse naphi na apho ufuna khona. Zonke izixhobo zomatshini ezichanekileyo zisebenzisa i-DC motor ukulawula ukuchaneka.
▶ 5. I-DC brush motor inexabiso eliphantsi kwaye kulula ukuyigcina.
Ngenxa yobume bayo obulula, ixabiso eliphantsi lemveliso, abavelisi abaninzi kunye nobuchwepheshe obuqolileyo, i-DC brush motor isetyenziswa kakhulu kwaye ayibizi kakhulu. Itekhnoloji ye-Brushless motor ayikhuli, ixabiso liphezulu kwaye uluhlu lwesicelo lulinganiselwe. Kufuneka isetyenziswe ikakhulu kwisixhobo sesantya esingaguqukiyo, esifana ne-air conditioning frequency, ifriji, njl. njl.
▶ 6. Ibhrashi, uphazamiseko oluphantsi:
I-motor brushless isusa iibhulashi kunye nolona tshintsho oluthe ngqo kukungabikho kweentlantsi zombane eziveliswayo xa i-motor brushless isebenza, enciphisa kakhulu ukuphazamiseka kombane kwisixhobo somsakazo olawulwa kude.
