Menene injin da ba shi da goge-goge - ƙa'idar aiki

Motar wutar lantarki ta DC mara goga (Motar BLDC ko BL motor) tana amfani da na'urori masu sauyawa na semiconductor don gane ma'amala ta lantarki, wato, na'urorin canza wutar lantarki maimakon na'urar sadarwa ta gargajiya da goga.Yana da fa'idodin babban aminci, babu walƙiya mai motsi, ƙaramar hayaniyar inji. da sauransu.Ana amfani da shi sosai a babban wurin rikodi, mai rikodin bidiyo, kayan lantarki da kayan aikin ofis.

Motar DC mara nauyi An hada da na'ura mai juyi mai jujjuyawar maganadisu na dindindin, stator-pole winding stator da firikwensin matsayi.Mahimman matsayi bisa ga canjin matsayi na rotor, tare da wani nau'in juzu'in na'ura mai juyi na yanzu (watau gano ma'aunin maganadisu na maganadisu dangane da matsayin stator winding). , da kuma ƙayyade wurin siginar firikwensin matsayi, siginar siginar siginar don sarrafa ikon wutar lantarki, bayan aiki bisa ga ƙayyadaddun ma'auni tsakanin winding na yanzu). ta hanyar fitarwa na firikwensin matsayi.

Akwai nau'ikan firikwensin matsayi guda uku: Magnetic-sensitive, photoelectric da electromagnetic.

Motar DC maras goge tare da firikwensin matsayi na maganadisu, sassan firikwensin maganadisu (kamar hall element, magnetin sensitive diode, magnetic-sensitive pole tube, Magnetic-sensitive resistor ko na musamman hadedde da'ira, da sauransu) an sanya su a kan stator. taro don gano sauye-sauyen filin maganadisu wanda ya haifar da maganadisu na dindindin da jujjuyawar juyi.

Motar DC maras goga tare da firikwensin matsayi na hoto an sanye shi da firikwensin hoto a wani matsayi a kan taron stator, an shigar da allo akan rotor, kuma ana jagorantar tushen haske ko ƙaramin kwan fitila.Lokacin da rotor ke juyawa, saboda rawar na rufewa, abubuwan da ke ɗaukar hotuna a kan stator za su haifar da siginar bugun jini a wani lokaci.

Amfani da electromagnetic matsayi firikwensin brushless dc motor, shi ne a cikin electromagnetic na'urori masu auna firikwensin da aka shigar a kan stator bangaren sassa (kamar hada biyu mai canzawa, kusa da sauyawa, LC resonance kewaye, da dai sauransu), lokacin da m magnet rotor matsayi canje-canje, electromagnetic sakamako zai. sa na'urar firikwensin lantarki yana samar da siginar haɓakar mitar mitar (amplitude yana canzawa tare da matsayi na rotor)

JIUYUAN yana da gogewa sama da shekaru 20 akankaramin motar dc mara goge,Motar dc na rotor mara kyau,inner rotor brushless dc motor, babur dc motor tare da mai sarrafawa ko tuƙi da sauransu.
