Galimoto ya brushless DC imakhala ndi galimoto komanso dalaivala, ndipo ndi chinthu wamba chamagetsi.Chifukwa brushless DC motor imagwira ntchito modziletsa, sichidzawonjezera mafunde oyambira ku rotor ngati motor synchronous yokhala ndi katundu wolemetsa kuyambira pansi pa ma frequency frequency regulation, komanso sizimayambitsa kugwedezeka ndi kutayika kwa masitepe pamene katundu asintha. mwadzidzidzi.Maginito osatha a ma motors ang'onoang'ono komanso apakatikati a brushless DC tsopano amapangidwa kwambiri ndi zinthu zapadziko lapansi za neodymium-iron-boron (Nd-Fe-B) zokhala ndi mphamvu zamaginito.Choncho, voliyumu ya osowa padziko lapansi okhazikika maginito brushless galimoto imachepetsedwa ndi chimango chimodzi kukula poyerekeza ndi magawo atatu asynchronous galimoto ya mphamvu yomweyo.
Galimoto yopukutidwa: Galimoto yopukutidwa imakhala ndi chipangizo cha burashi, ndipo ndi injini yozungulira, yomwe imatha kusintha mphamvu yamagetsi kukhala mphamvu yamakina (motor), kapena kusintha mphamvu yamakina kukhala mphamvu yamagetsi (jenereta).Mosiyana ndi ma motors opanda ma brushless, zida za burashi zimagwiritsidwa ntchito poyambitsa kapena kuchotsa magetsi ndi apano.The brushed motor ndiye maziko a motors onse.Ili ndi mawonekedwe oyambira mwachangu, ma braking munthawi yake, kuwongolera liwiro mosiyanasiyana, komanso dera losavuta lowongolera.
Mfundo yogwiritsira ntchito brushed motor ndi brushless motor.
1. Makina opukutira
injini ikugwira ntchito, koyilo ndi commutator zimazungulira, koma chitsulo cha maginito ndi burashi ya kaboni sizizungulira.Kusintha kosinthika komwe kumayendera komweko kwa koyilo kumakwaniritsidwa ndi commutator ndi burashi yomwe imazungulira ndi mota.M'makampani amagetsi amagetsi, ma motors opukutidwa amagawidwa kukhala ma motors othamanga kwambiri komanso ma motors othamanga kwambiri.Pali kusiyana kwakukulu pakati pa ma motors brushed motors ndi brushless motors.Kuchokera pa dzinali, zitha kuwoneka kuti maburashi opukutidwa ali ndi maburashi a kaboni, ndipo maburashi opanda kaboni alibe maburashi a kaboni.
The burashi galimoto lili ndi magawo awiri: stator ndi rotor.Stator ili ndi mitengo ya maginito (mtundu wokhotakhota kapena mtundu wokhazikika wa maginito), ndipo rotor ili ndi mafunde.Pambuyo pamagetsi, maginito (magnetic pole) amapangidwanso pa rotor.Kuphatikizikako kumapangitsa kuti injiniyo izungulire pansi pa kukopa kwa maginito a stator ndi rotor (pakati pa N pole ndi S pole).Posintha malo a burashi, ngodya pakati pa stator ndi rotor maginito mitengo ingasinthidwe (poganiza kuti maginito pole ya stator imayambira pa ngodya, maginito pole ya rotor ili mbali inayo, ndi njira yochokera kumtunda. phata la maginito la rotor kupita ku maginito pole ya stator ndi njira yozungulira mozungulira) mayendedwe, motero kusintha komwe kumazungulira kwa injini.
2. Galimoto yopanda maburashi
Galimoto yopanda maburashi imatengera kusintha kwamagetsi, koyilo sikuyenda, ndipo maginito amazungulira.Galimoto yopanda maburashi imagwiritsa ntchito zida zamagetsi kuti izindikire malo a maginito okhazikika a maginito kudzera mu chinthu cha Hall.Malinga ndi lingaliro ili, dera lamagetsi limagwiritsidwa ntchito kusinthira njira yomwe ilipo mu coil mu nthawi kuti zitsimikizire kuti mphamvu ya maginito yomwe ili yoyenera imapangidwa kuti iyendetse galimotoyo, kuchotsa zofooka za galimoto yopukutidwa.
Mabwalo awa ndi owongolera magalimoto.Wolamulira wa motor brushless motor amathanso kuzindikira ntchito zina zomwe motor brushed siingathe, monga kusintha mphamvu yosinthira mphamvu, kubweza galimoto, kutembenuza galimoto, kutseka galimoto, ndi kugwiritsa ntchito chizindikiro cha brake kuyimitsa magetsi ku galimotoyo. .Tsopano chotchinga chamagetsi chamagetsi chagalimoto ya batri chimagwiritsa ntchito mokwanira ntchitozi.
Ubwino wosiyanasiyana wa ma motors opanda brushless ndi ma brushed motors
Galimoto ya brushed ili ndi ubwino wake, ndiko kuti, mtengo wake ndi wotsika komanso kuwongolera ndikosavuta.Mtengo wama motors opanda brush nthawi zambiri umakhala wokwera kwambiri, ndipo chidziwitso chaukadaulo chimafunikira pakuwongolera.Ndikukula kosalekeza kwaukadaulo waukadaulo wa brushless motor control, kutsika kwa mtengo wa zida zamagetsi, kuwongolera zomwe anthu amafuna pamtundu wazinthu, komanso kukakamizidwa pachitetezo chamagetsi ndikuchepetsa kutulutsa, ma motors ochulukirachulukira ndi ma AC motors adzasinthidwa ndi DC brushless motors.
Chifukwa cha kukhalapo kwa maburashi ndi ma commutators, ma motors opukutidwa amakhala ndi mawonekedwe ovuta, kudalirika kosadalirika, zolephereka zambiri, kulemedwa kwa ntchito yokonza, moyo waufupi, komanso zowotcha zosinthika zimatha kusokonezedwa ndi ma electromagnetic.Galimoto yopanda maburashi ilibe maburashi, kotero palibe mawonekedwe ogwirizana, kotero imakhala yoyera, imakhala ndi phokoso lochepa, imafuna kusamalidwa, ndipo imakhala ndi moyo wautali.
Kwa zinthu zina zotsika mtengo, ndizotheka kugwiritsa ntchito mota yama brushed, bola ngati isinthidwa munthawi yake.Komabe, pazinthu zina zamtengo wapatali, monga ma air conditioners, magalimoto, ndi osindikiza, mtengo wosinthira hardware ndi wokwera kwambiri, ndipo siwoyenera kusinthidwa pafupipafupi, motero ma motors opanda brushless a DC akhala abwino kwambiri. kusankha.
Shenzhen Zhongling Technology Co., Ltd yakhala ikuyang'ana kwambiri pa kafukufuku wa motor stepper ndi servo motor kuyambira pomwe idakhazikitsidwa, ndipo yapeza ma patent angapo ndipo ali ndi chidziwitso chochuluka.Ma stepper motors ndi ma servo motors opangidwa ndi kampaniyo amagulitsidwanso kunyumba ndi kunja, kukhala chisankho chabwino kwambiri kwamakampani ambiri amaloboti ndi makampani ambiri opanga zida zamagetsi.
