1. Umehluko wesimiso: ibhulashi motor ithatha ukushintsha kwemishini, isigxobo kazibuthe asinyakazi, i-cfuel iyajikeleza. Lapho i-motor isebenza, i-cfuel kanye ne-commutator iyazungeza, i-magnet ne-carbon brush ayijikelezi, futhi ukuguqulwa okushintshwayo kwesikhombisi-ndlela samanje se-cfuel kufezwa umshini kanye nebhulashi elizungeza injini. I-Brushless motor isebenzisa ukushintshwa kwe-elekthronikhi, i-cfuel ayinyakazi futhi isigxobo kazibuthe siyazungeza.
2. Umehluko wemodi yokulawula isivinini: Eqinisweni, zombili izinjini zilawulwa yi-voltage regulation, kuphela ngenxa yokuthi i-brushless DC isebenzisa ukushintshwa kwe-electronic, ukulawula kwedijithali kuyadingeka. I-Brushless DC ishintshwa nge-carbon brush, futhi ingalawulwa ngamasekethe e-analog endabuko afana ne-silicon controlled, elula kakhulu.
Umehluko ekusebenzeni:
▶ 1. I-brush motor inesakhiwo esilula, isikhathi eside sokuthuthukiswa kanye nobuchwepheshe obuvuthiwe.
Emuva nje kokuzalwa kwemoto ngekhulu leshumi nesishiyagalolunye, injini esebenzayo eyakhiwe yayiyi-brushless, okungukuthi i-AC squirrel-cage asynchronous motor, esetshenziswe kabanzi kusukela ekukhiqizeni i-AC. Kodwa-ke, kuneziphambeko eziningi ezingenakunqotshwa ku-asynchronous motor, ukuze ukuthuthukiswa kobuchwepheshe bezimoto kuhamba kancane.
▶ 2. I-DC brush motor inesivinini sokuphendula esisheshayo kanye ne-torque enkulu yokuqala:
I-DC brush motor inempendulo eqala ngokushesha, i-torque enkulu eqalayo, ukuguqulwa kwesivinini esibushelelezi, futhi ayikwazi ukuzwa ukudlidliza ukusuka ku-zero kuye kwesivinini esiphezulu. Ingakwazi ukushayela umthwalo omkhulu uma iqala. I-Brushless motor inokumelana nokuqala okukhulu (i-inductance), ngakho-ke inamandla amancane, i-torque yokuqala encane uma iqala, iyantweza lapho iqala, ihambisana nokudlidliza okuqinile, umthwalo omncane wokushayela lapho uqala.
▶ 3. I-DC brush motor isebenza kahle futhi inesiqalo esihle kanye nokubhuleka:
Izinjini zamabhulashi zilawulwa yi-voltage, ngakho-ke qala futhi ubhuleke kahle futhi ugijime kahle ngesivinini esingaguquki. Amamotho angama-Brushless ngokuvamile alawulwa ukuguqulwa kwamafrikhwensi edijithali. Okokuqala i-AC iguqulwa ibe yi-DC, bese kuthi i-DC ibe yi-AC. Isivinini silawulwa ukushintsha kwefrikhwensi. Ngakho-ke, ama-brushless motors agijima ngokungalingani lapho eqala futhi ebhuleka, ngokudlidliza okukhulu, futhi kuphela uma isivinini sihlala njalo azohamba kahle.
▶ 4. Ukulawula ukunemba okuphezulu kwe-DC brush motor:
I-DC brush motor ivamise ukusetshenziswa kanye ne-gearbox kanye ne-decoder, okwenza amandla okukhipha imoto abe makhudlwana nokulawula ukunemba kuphakeme. Ukunemba kokulawula kungafinyelela ku-0.01 mm, futhi kungamisa izingxenye ezihambayo cishe noma kuphi lapho ufuna. Wonke amathuluzi omshini wokunemba asebenzisa injini ye-DC ukulawula ukunemba.
▶ 5. I-DC brush motor inezindleko eziphansi kanye nokugcinwa kulula.
Ngenxa yesakhiwo sayo esilula, izindleko eziphansi zokukhiqiza, abakhiqizi abaningi nobuchwepheshe obuvuthiwe, i-DC brush motor isetshenziswa kabanzi futhi ayibizi kakhulu. I-Brushless motor technology ayikavuthwa, intengo iphezulu futhi nebanga lesicelo lilinganiselwe. Kufanele isetshenziswe kakhulu ezintweni zesivinini esingaguquki, njenge-variable frequency air conditioning, isiqandisi, njll. Ukulimala kwemoto engenamabhulashi kungashintshwa kuphela.
▶ 6. Ibhulashi, ukuphazamiseka okuphansi:
I-brushless motor isusa amabhulashi futhi ukuguqulwa okuqondile kakhulu ukungabikho kwezinhlansi zikagesi ezikhiqizwa lapho i-brushless motor isebenza, okunciphisa kakhulu ukuphazanyiswa kwezinhlansi zikagesi emshinini womsakazo olawula kude.
