DC motor - kunye brushless ngobuwena collectron

iimoto zombane lungahlulwa-hlulwa ibe iintlobo ezimbini ngokwenjongo yayo: generator DC motor. Okumangalisayo kukuba, basebenza phantse ukukhetha. Umahluko kuphela kukuba le generator iguqula amandla ngomatshini le plane kwi lo mhlaba otsalayo eveliswe stator osuka kwi yombane motor - ngokuchasene (esiguqula amandla ombane abe ngamandla rotation, ngamanye mechanical).

I-DC motor ine-armature kunye vee e ababhexeshi yayo zipakishwe ukwakhiwa kwayo. Isigaba sesibini iphambili yale matshini lizoqala kunye stator excitation yayo kunye nezibonda ezininzi. Umgaqo ekusebenzeni sixhobo ilula. Ngokugqithisela uhamba ngocingo phezulu armature DC ngoku kumacala ahlukeneyo (icala elinye "thina" kunye nezinye "nathi"). Ngokutsho ezaziwayo-kakuhle ulawulo elisekhohlo, ezo abaqhubi ukuba phezulu, uya bayacalulwa le stator mhlaba otsalayo wadala yi ekhohlo umqhubi ilahlwe kwi emazantsi armature, uya kwabeka ekunene.

Ekubeni ababhexeshi ngobhedu Kwabekwa vee, amandla ziza kutshintshelwa ankile uphendule ngayo.

Xa indawo enye provernetsya umqhubi ize ime malunga kwipali ngasezantsi stator ukuqala umsebenzi elekhtrons i (ukuqala Umqhubi icinezelwe kwi kwicala lasekhohlo). Ukunqanda le nkqubo kuyimfuneko ukutshintsha ulwalathiso zangoku ngocingo. Ukulungiselela le njongo, ebizwa ngokuba zininzi kunye injini nomgaqo yokusebenza kuthiwa DC commutator motor.

It engathi armature uya nokudlulisela torque kwizikhondo iimoto, yaye omnye - ziqale izixhobo noomatshini eziyimfuneko. Kufuneka kuqatshelwe ukuba yonke umgaqo esi sixhobo isekelwe phezu inversion le DC kwi kwikhonkco ankile.

Noko ke, kukho injini brushless DC. Mu kuya kwa nshita umqokeleli, oko ayinayo isixhobo yakhe iibhrashi ezidale iingozi ezongezelelweyo ngexesha lokusebenza injini (iibhrashi tipakani ngokuchasene plane ejikelezayo kwaye kudala enizenze ukuze phemba kakubi zigqunyiwe iinxalenye umatshini zombane).

dc motor ngaphandle umqokeleli uye iibheringi zayo zoyilo izilawuli ezizodwa ikwazi ukubonelela zonke iinkqubo ziguquka ngaphakathi injini. Ukongeza, iye microactuators abanama-ngqo endaweni.

Kungenxa yoko le nto sixhobo siya kuxabisa kakhulu ngaphezu kokuba eqhelekileyo Motors ibrashi DC. Nangona kunjalo, ukusetyenziswa kwe-injini enjalo bugwetyelwe ngokupheleleyo: ukwandisa iyahlala yayo, ukuthembeka, ukhuseleko. iphezulu kakhulu kunye nokusebenza (COP), kunye ukuxhathisa nomthwalo.

Ngokungafaniyo DC commutator motor, ngempumelelo kuphuculo imodeli brushless ephelisiweyo ziqhubela kuhlaziywa. Umzekelo, kakhulu eziphuhliswe kutsha nje non-contact ontlantlu-ntathu dc motor ngaphandle umqokeleli.
