Chiyambi:
Kwa ndege, magalimoto, kapena makina opanga mafakitale, mphamvu zama injini othamanga kwambiri ndizofunikira kwambiri. Komabe, kuthamanga kwambiri nthawi zonse kumabweretsa kukweramafunde a eddyndiyeno kumabweretsa kutayika kwa mphamvu ndi kutentha kwambiri, komwe kumakhudza magwiridwe antchito agalimoto pakapita nthawi.
Ndichifukwa chakeanti-eddy maginito apanoszakhala zofunika. Maginitowa amathandiza kulamulira mafunde a eddy, kusunga ma motors kutentha ndi kuyenda bwino kwambiri—makamaka mu maginito okhala ndi maginito ndi ma injini onyamula mpweya. M'nkhaniyi, tifotokoza momwe ukadaulo uwu umagwirira ntchito komanso chifukwa chomwe zinthu za“MagnetPower”ndi oyenerera makamaka, chifukwa cha mphamvu zawo zapamwamba komanso kutentha kochepa.
1. The Eddy Currents
Mafunde a Eddy adayambitsidwa ndi "MagnetPower”m'nkhani zakale).
M'ma motors othamanga kwambiri, monga omwe amagwiritsidwa ntchito muzamlengalenga kapena kompresa (Liwiro la mzere ≥ 200m/s), mafunde a eddy amatha kukhala vuto lalikulu. Amapanga mkati mwa ma rotors ndi stators pamene maginito amasintha mofulumira.
Mafunde a Eddy sizovuta zazing'ono; amatha kuchepetsa mphamvu zamagalimoto ndipo amatha kuwononga pakapita nthawi. Zikuwonetsedwa motere:
- Kutentha Kwambiri: Mafunde a Eddy amatulutsa kutentha, komwe kumapangitsa kuti pakhale kupsinjika kwambiri pamagalimoto. Mwachitsanzo, Kutayika kwa maginito kosasinthika kwa maginito okhazikika NdFeB kapena SmCo nthawi zonse zimachitika chifukwa cha kutentha kwambiri.
- Kutaya Mphamvu: mphamvu ya injiniyo idachepa chifukwa mphamvu yomwe imatha kuyendetsa galimotoyo imawonongeka popanga mafunde a eddy awa.
2. Momwe Anti-Eddy Current maginito Amathandizira
Anti-eddy maginito apanozakonzedwa kuti zithetse vutoli molunjika. Pochepetsa momwe mafunde a eddy amapangidwira komanso komwe amapangidwira, amawonetsetsa kuti injiniyo ikuyenda bwino komanso imakhala yozizira. Njira imodzi yothandiza yotsekereza mafunde a eddy ndikupanga maginito mu kapangidwe ka lamination. Njirayi imatha kuthyola njira yapano ya eddy, ndiyeno imalepheretsa mafunde akulu, ozungulira kuti asapangike.
3. Chifukwa MagnetPower Chatekinoloje a Misonkhano Ndi Abwino kwa High-Liwiro Motors
Tsopano, tiyeni tilowe mumadzimadzi muzabwino zaZithunzi za MagnetPoweranti-eddy panopa misonkhano. Misonkhanoyi ndi yabwino kwa maginito okhala ndi maginito ndi ma mota okhala ndi mpweya, omwe amapereka kuphatikiza kwamphamvu kwambiri, kutulutsa kutentha kochepa, komanso kuchuluka kwa moyo wamagalimoto.
3.1 Kukaniza Kwambiri = Kuchita Bwino Kwambiri
Maginito odana ndi eddy omwe amapangidwa ndi "Magnet Power" ndikugwiritsa ntchito guluu wotsekereza pakati pa zigawo za maginito ogawanika, amawonjezera kukana kwamagetsi, pamwamba pa 2MΩ · cm. Ndikoyenera kuswa njira yapano ya eddy. Choncho, kutentha sikophweka kupangidwa. Izi ndizofunikira kwambiri pamagalimoto onyamula maginito. Pochepetsa kutentha, maginito a MagnetPower amawonetsetsa kuti ma mota amayenda bwino pa liwiro lalikulu popanda chiwopsezo cha kutenthedwa. Ndi chimodzimodzi kwamakina onyamula mpweya-kutsika kutentha kumapangitsa kusiyana kwa mpweya pakati pa rotor ndi stator, yomwe ndi mfundo yofunika kwambiri yolondola.
Chithunzi 1 maginito odana ndi eddy omwe amapangidwa ndi Magnet Power
3.2 High maginito flux
Maginito amapangidwa ndi makulidwe a 1mm ndipo amakhala ndi wosanjikiza woonda kwambiri wa 0.03mm. Izi zimapangitsa kuti guluu likhale laling'ono komanso kuchuluka kwa maginito kumakhala kwakukulu momwe mungathere.
3.3 mtengo wotsika
Izi komanso amachepetsa zofuna coercivity ndi ndalama pamene utithandize bata matenthedwe, Makamaka maginito NdFeB. Ngati kutentha kwa rotor kumatha kuchepetsedwa kuchokera ku 180 ℃ mpaka 100 ℃, giredi ya maginito imatha kusinthidwa kuchokera ku EH kupita ku SH. Izi zikutanthauza kuti mtengo wa maginito ukhoza kuchepetsedwa ndi theka.
4. Momwe maginito a MagnetPower amachitira mu High-Speed Motors
Tiyeni tiwone machitidwe a MagnetPower's anti-eddy maginito apano mumagetsi okhala ndi maginito ndi ma mota okhala ndi mpweya.
4.1 Magnetic Bearing Motors: Kukhazikika Pakuthamanga Kwambiri
Mu maginito okhala ndi maginito, maginito onyamula maginito amasunga rotor kuyimitsidwa, kuilola kuti izizungulira popanda kukhudza mbali zina zilizonse. Koma chifukwa champhamvu kwambiri (yopitilira 200kW) komanso kuthamanga kwambiri (kupitilira 150m/s, kapena kupitilira 25000RPM), eddy pano sizovuta kuwongolera. Fig.2 ikuwonetsa rotor ndi liwiro la 30000RPM. Chifukwa cha kutayika kochuluka kwa eddy panopa, kutentha kwakukulu kunapangidwa, zomwe zimapangitsa kuti rotor ikhale ndi kutentha kwakukulu kuposa 500 ° C.
Maginito a MagnetPower amathandizira kupewa izi pochepetsa mapangidwe amakono a eddy. Kutentha kwa rotor yowongoka sikunapitirire 200 ℃ mumayendedwe omwewo.3
Fig.2 rotor pambuyo poyesedwa ndi liwiro la 30000RPM.
4.2 Air Bearing Motors: Precision pa High Speed
Ma injini okhala ndi mpweya amagwiritsa ntchito filimu yopyapyala ya mpweya yomwe imapangidwa mozungulira mothamanga kwambiri kuti ithandizire rotor. Ma motors awa adapangidwa kuti azigwira ntchito mothamanga kwambiri, ngakhale mpaka 200,000RPM, mosaneneka. Komabe, mafunde a eddy amatha kusokoneza kulondola koteroko potulutsa kutentha kochulukirapo ndikusokoneza kusiyana kwa mpweya.
Ndi maginito a MagnetPower, mafunde a eddy amachepetsedwa, zomwe zikutanthauza kuti galimotoyo imakhala yozizira komanso imasunga mpweya wokwanira wofunikira pakugwiritsa ntchito bwino kwambiri ngati Hydrogen fuel cell compressor ndi blower.
Mapeto
Zikafika pamakina othamanga kwambiri, kuchepetsa kutayika kwa mphamvu ndikuwongolera kutentha ndikofunikira pakuwongolera magwiridwe antchito ndikutalikitsa moyo wa zida zanu. Ndipamene maginito a MagnetPower odana ndi eddy amabwera.
Chifukwa chogwiritsa ntchito zida zotha kukana kwambiri, mapangidwe anzeru ngati magawo ndi kuyika, komanso kuyang'ana kwambiri pakuchepetsa mafunde a eddy, mabwalowa amathandiza ma mota kuti aziyenda mozizira, mwaluso, komanso kwanthawi yayitali. Kaya ndi maginito okhala ndi maginito, ma mota okhala ndi mpweya, kapena ntchito zina zothamanga kwambiri, MagnetPower ikukankhira malire a zomwe zingatheke pakuchita bwino komanso kudalirika kwagalimoto.
