Ishyirwa mu bikorwa rya moteri ya DC idafite brushless mu bikoresho by'amashanyarazi

Bitewe no kunoza ikoranabuhanga rishya ryo kugenzura bateri n'ikoranabuhanga, ikiguzi cyo gushushanya no gukora moteri ya DC idafite uburoso cyaragabanutse cyane, kandi ibikoresho byoroshye bishobora kongera gukoreshwa bisaba moteri ya DC idafite uburoso byaramamaye kandi bikoreshwa cyane. Ikoreshwa cyane mu nganda zikora, ziteranya kandi zisana, cyane cyane bitewe n'iterambere ry'ubukungu, icyifuzo cy'ingo nacyo kirimo kwiyongera, kandi igipimo cy'izamuka ry'umwaka kiri hejuru cyane ugereranyije n'izindi nganda.

2, ubwoko bworoshye bwo gukoresha moteri y'ibikoresho by'amashanyarazi ishobora kongera gukoreshwa

2.1 Moteri ya DC ifite brush

Imiterere isanzwe ya moteri ya DC idafite uburoso irimo rotor (umugozi, icyuma, winding, commutator, bearing), stator (igisenge, magnet, impera y'inyuma, nibindi), guteranya uburoso bwa karuboni, ukuboko kwa brush ya karuboni n'ibindi bice.

Ihame ry'imikorere: Stator ya moteri ya DC ikozwe muri brushed ishyirwaho inkingi ikomeye (magnet) na brush, kandi rotor ishyirwaho na armature winding na commutator. Ingufu z'amashanyarazi z'amashanyarazi ya DC zinjira muri armature winding binyuze muri brush ya karuboni na commutator, zigatanga armature current. Imbaraga rukuruzi zikorwa na armature current zikorana n'imbaraga rukuruzi kugira ngo zikore torque ya electromagnetic, ituma moteri izenguruka kandi igatwara umutwaro.

Ingaruka mbi: Kubera ko hari brush ya karuboni na commutator, ubwizigengeri bwa moteri ya brush ni bubi, gutsindwa, kudahinduka kw'amashanyarazi, igihe gito cyo kubaho, kandi commutator spark bizatera electromagnetic interference.

2.2 Moteri ya DC idafite uburoso

Imiterere isanzwe ya moteri ya DC idafite uburoso irimo rotor ya moteri (umugozi, icyuma, magnet, bearing), stator (agasanduku, icyuma, winding, sensor, impera, nibindi) hamwe n'ibice bigenzura.

Ihame ry'imikorere: Moteri ya DC idafite brush igizwe n'umubiri wa moteri n'umushoferi, ni ikintu gisanzwe gikoreshwa mu gukora ikoranabuhanga rya mechatronics. Ihame ry'imikorere ni rimwe n'irya moteri ya brush, ariko commutator isanzwe na brush ya karuboni bisimburwa na sensor y'aho ibintu biri n'umurongo wo kugenzura, kandi icyerekezo cy'amashanyarazi gihindurwa n'itegeko ryo kugenzura ritangwa n'ikimenyetso cyo kumva kugira ngo imikorere igende neza, kugira ngo hamenyekane ko moteri ihora ikora neza kandi iyobore neza, bityo moteri izunguruka.

Isesengura rya moteri ya DC idafite brushless mu bikoresho by'amashanyarazi

3. Ibyiza n'ibibi byo gukoresha moteri ya BLDC

3.1 Ibyiza bya moteri ya BLDC:

3.1.1 Imiterere yoroshye n'ubwiza bwizewe:

Guhagarika commutator, brush ya karuboni, brush arm n'ibindi bice, nta gusudira commutator, inzira yo kurangiza.

3.1.2 Igihe kirekire cyo gukora:

Gukoresha ibice by'ikoranabuhanga kugira ngo bisimbure imiterere gakondo ya commutator, gukuraho moteri bitewe n'uburoso bwa karuboni n'ingufu za commutator, kwangirika kwa mekanike n'ibindi bibazo biterwa no kumara igihe gito, igihe cy'imodoka cyongerwaho inshuro nyinshi.

3.1.3 Umusaruro utuje kandi woroshye:

Nta burashi ya karuboni n'imiterere ya commutator, irinde ko commutator yangiza n'ubushyamirane hagati ya brush ya karuboni n'imashini, bigatera urusaku, ubushyuhe, gutakaza ingufu za moteri, bigagabanya imikorere ya moteri. Umusaruro wa moteri ya DC idafite uburoso kuri 60 ~ 70%, kandi imikorere ya moteri ya DC idafite uburoso ishobora kugera kuri 75 ~ 90%.

3.1.4 Ubushobozi bwagutse bwo kugenzura umuvuduko no kuwugenzura:

Ibice by'ikoranabuhanga n'ibikoresho by'ikoranabuhanga bigezweho bishobora kugenzura neza umuvuduko w'ibisohoka, torque n'aho moteri iherereye, bigatuma moteri ikora neza kandi ifite imikorere myinshi.
