DC motor - futhi brushless samuntu collectron

izimoto Electric zingahlukaniswa zibe izinhlobo ezimbili ngokwenjongo yabo: i-generator nomshini DC motor. Ngokuphawulekayo, basebenza cishe ngokufana ncamashí. Umahluko owokuthi ukuthi generator oguqula amandla mechanical Rotor e kazibuthe ezivezwa stator emazombezombe e kagesi kanye motor - okunalokho (oguqula amandla kagesi zibe amandla ukujikeleza, isb mechanical).

I DC motor ine armature nge anemifantu e babashayeli yayo embondelene in isakhiwo sabo. Ingxenye yesibili esemqoka yalolu mshini emazombezombe futhi stator excitation yayo lemijabo amaningi. Umgomo we operation sedivayisi ezifana ulula. Ngu edabula wire phezulu armature DC zamanje bacondze etindzaweni letehlukene (uhlangothi "nathi" kanye nezinye "kithi"). Ngokusho owaziwa sobunxele umthetho, labo babashayeli ukuthi ziphezulu, uzobe zinganakiwe stator kazibuthe adalwe kwesokunxele bese umqhubi ngokufanele ezansi le armature, abayosunduzelwa ngakwesokudla.

Njengoba babashayeli zethusi sibekwa anemifantu, umfutho ngeke adluliselwe ihange futhi usijikeleze.

Lapho enye ingxenye provernetsya umqhubi futhi ume okuphambene isigxobo eningizimu stator ukuqala ukusebenza unyathela amabhuleki (ukuqala umqhubi ocindezelwe ohlangothini lwesobunxele). Ukuvimbela lokhu inqubo kuyadingeka ukushintsha isiqondiso samanje wire. Ngenxa yale njongo, okuthiwa ezininginingi futhi injini ne Umgomo we operation ngokuthi DC commutator motor.

It armature Windings batawedlulisela torque engu kushaft motor, umuntukazana - waqalisa adingekayo imishini nemishini. Kufanele kuqashelwe ukuthi wonke isimiso salesi imishini kusekelwe kombhala we DC ku uchungechunge ihange.

Nokho, kukhona injini brushless DC. Ngokungafani ngalendoda, ayinayo kudivayisi lakhe emabhulashini ukuthi ukudala izingozi ezengeziwe ngaleso ukusebenza injini (emabhulashini ukukuthinta ngokumelene Rotor ligijima futhi zingakwazi ukukhiqiza izinhlansi engase okhela kahle ngci kagesi izingxenye zemishini).

dc motor ngaphandle ngalendoda anayo nomklamo walo amabombo kanye abalawuli ekhethekile zahlelwa ukuthi uhlinzeka ngazo zonke izinqubo usuke ngaphakathi injini. Ngaphezu kwalokho, it has microactuators nge high-ukucacisa ukuma.

Yingakho leli thuluzi izobiza kakhulu ngaphezu esiku DC ibhulashi izinjini. Nokho, ukusetshenziswa injini enjalo ulungisiswa ngokuphelele: ukwandisa ukuqina yayo, ukuthembeka, ukuphepha. Siphezulu futhi nekusebenta (COP), kanye ukumelana overloads.

Ngokungafani DC commutator motor, okuyinto ngempumelelo nokuthuthukela wayekwa imodeli brushless is ngokuqhubekayo olusha. Ngokwesibonelo, muva nje athuthukile-non-contact ezintathu okhombisa dc motor ngaphandle ngalendoda.
