Ukadaulo wamagetsi ochepetsa kutentha umathandizira kwambiri kuthekera kogwira ndi kuteteza maginito opanda brushless motor

Kutentha kwa Multilayer kumachepetsa machubu okhala ndi kukana kwamakina apamwamba komanso kutenthetsa kokwanira kuti ateteze ndi kuteteza ma rotor opanda ma motor, kusanja mitundu yonse ya mphamvu zama centrifugal zogwiritsidwa ntchito pa maginito okhazikika.Palibe chowopsa chophwanyidwa kapena kuwononga maginito okhazikika panthawi ya msonkhano.Ili ndi ubwino wa mgwirizano wangwiro ngakhale m'mphepete mwa rotor.Kuphatikiza apo, ulusi wagalasi mkati mwa manja otsika kutentha umakhalanso ndi mphamvu zamakina kwambiri komanso kukana kutentha, ndipo kutentha komwe kumagwiritsidwa ntchito pochepetsa kutentha kumakhala kotsika kwambiri kuposa Curie point, komwe sikungachepetse kutulutsa kwa maginito kwa maginito.

 

Ikani manja ochepetsetsa kutentha pa rotor, maginito ali m'malo mwake, ndipo kutentha kumachepa (pogwiritsa ntchito kutentha kochepa kwambiri kuposa malo a Curie ndikupewa chiopsezo cha kutayika kwa madzi), kumamatira kolimba kumapezeka ngakhale pa rpm .Imalimbananso ndi kutenthedwa kwa kutentha pamene injini ikuyenda kwa nthawi yayitali (mpaka 180 ° C).Zotayika zaposachedwa za Eddy zimapewedwa poyerekeza ndi manja achitsulo okwera mtengo kwambiri, omwe amachepetsa mphamvu zamagalimoto ndipo angayambitse injini kutenthedwa.Chifukwa cha makulidwe ake ochepa pakati pa 0.19-0.35 mm, mkonowo umatsimikizira kuti maginito abwino kwambiri okhazikika komanso magwiridwe antchito apamwamba a maginito, motero amatsimikizira kugwira ntchito kwabwino kwa injiniyo.

Ubwino wina wofunikira womwe machubu amawotcha amaphatikiza: Mosiyana ndi mphete zachitsulo zamtengo wapatali kwambiri, kutentha kwa chubu kumazungulira ndikuteteza malekezero a maginito, omwe amathanso kuwononga dzimbiri, omwe, ngati atasweka, angayambitse kupanikizana kwa injini.Kupewa kudula panthawi yosonkhanitsa pogwiritsa ntchito mphete zolimba, chubu chochepetsera kutentha chimamamatira bwino maginito, chimasunga mawonekedwe ake ndikuletsa kusweka ndi kukanda.Ngati maginito amamatiridwa pa malo ozungulira, malingana ndi kuchuluka kwa guluu wogwiritsidwa ntchito pa maginito aliwonse, pakhoza kukhala zovuta zina ndi kayendedwe ka rotor, zomwe zikutanthauza kukhazikitsa dongosolo lina lovuta kuti ligwirizane ndi rotor, zomwe zimawonjezera kuchuluka kwa zowonongeka. .

Kutentha kwapang'onopang'ono kumachepetsa machubu kuti azitha kuwongolera zozungulira, kuchepetsa zinyalala zopanga, kuyang'anira kuwongolera ngati gawo la msonkhano utha kuthetsedwa, kuchotsa ndalama zomwe zingakhale zokwera mtengo, ndikuchotsa kufunika kolumikizana ndi tepi yolumikizidwa ndi epoxy Imapewanso kuyambitsa pang'onopang'ono utomoni. nthawi mu uvuni, potero kuwongolera zokolola ndikuchepetsa ndalama zobisika zopangira.Machubu ochepetsa kutentha angagwiritsidwenso ntchito bwino molumikizana ndi guluu wa epoxy wogwirizira maginito, kuwonetsetsa kuti chitetezo chowonjezera pakulephera kwa guluu ndi kutsekeka kwa maginito, komanso kukwapula kapena zoipitsa zina.

 

Pomaliza

Mu motors ntchito mphete maginito psinjika kuumbidwa kuchokera Nd-Fe-B NdFeB maginito ndi Kuwonjezera thermosetting utomoni (pulasitiki ferrite), kutentha kuotcha manja amatetezanso maginito kuwonongeka chifukwa brittleness aloyi ntchito dzimbiri, motero kupewa motere kuti asagwedezeke.Chubu cha polyester chotenthetsera kutentha chimatsimikiziranso kutsekemera kwamafuta (Kalasi B), dielectric (4-5 kV) kutchinjiriza, ndipo imagwiritsidwa ntchito pa kutentha mpaka 150-155 ° C pachimake.Pezani mwachangu komanso mosavuta makulidwe, kukula ndi kulemera kwa maginito okhazikika pamakina opanga makina, kumathandizira kumamatira kwabwino kwa machubu ocheperako kutentha ku ma rotor ndi maginito, ndikukwaniritsa zotsika mtengo komanso zosavuta kuphatikizira pakubwezeretsanso maginito okhazikika.
