Tesla adalengeza lero pa tsiku lake la Investor kuti kampaniyo ipanga galimoto yamagetsi yamagetsi yopanda maginito yopanda padziko lapansi.
Zosowa zapadziko lapansi ndizomwe zimakangana pamagalimoto amagetsi chifukwa zinthu zimakhala zovuta kupeza ndipo zambiri zomwe zimapangidwa padziko lapansi zimapangidwa kapena kukonzedwa ku China.
Izi ndizofunikira pazifukwa zingapo, osati zochepa zomwe oyang'anira a Biden akuyendetsa pano kuti apange zida zamagalimoto amagetsi apanyumba.
Komabe, pali malingaliro olakwika okhudza zomwe REE ndi kuchuluka kwa REE yomwe imagwiritsidwa ntchito pamagalimoto amagetsi.M'malo mwake, mabatire a lithiamu-ion nthawi zambiri sakhala ndi maiko osowa (ngakhale amakhala ndi "minerals ina yofunika" monga tafotokozera ndi Inflation Reduction Act).
Mu tebulo la periodic, "rare earths" ndi zinthu zomwe zawonetsedwa mofiira mu chithunzi pansipa - lanthanides, komanso scandium ndi yttrium.M'malo mwake, sizosowa kwenikweni, ndi neodymium pafupifupi magawo awiri mwa atatu a mkuwa.
Zinthu zapadziko lapansi zomwe sizipezeka m'magalimoto amagetsi zimagwiritsidwa ntchito pamagalimoto amagetsi, osati mabatire.Zomwe zimagwiritsidwa ntchito kwambiri ndi neodymium, maginito amphamvu omwe amagwiritsidwa ntchito poyankhula, ma hard drive ndi ma motors amagetsi.Dysprosium ndi terbium ndizowonjezera zomwe zimagwiritsidwa ntchito popanga maginito a neodymium.
Komanso, si mitundu yonse yamagalimoto amagetsi omwe amagwiritsa ntchito ma REE-Tesla amawagwiritsa ntchito mumagetsi ake okhazikika a DC, koma osati m'magalimoto ake a AC.
Poyambirira, Tesla adagwiritsa ntchito ma AC induction motors m'magalimoto ake, omwe sanafune dziko lapansi losowa.Kwenikweni, apa ndipamene dzina la kampaniyo linachokera - Nikola Tesla ndiye adayambitsa injini ya AC induction motor.Koma Model 3 itatuluka, kampaniyo idayambitsa injini yamagetsi yatsopano yokhazikika ndipo pamapeto pake idayamba kuzigwiritsa ntchito pamagalimoto ena.
Tesla adanena lero kuti zatha kuchepetsa kuchuluka kwa dziko lapansi losowa lomwe limagwiritsidwa ntchito muzitsulo zatsopano za Model 3 ndi 25% pakati pa 2017 ndi 2022 chifukwa cha kupititsa patsogolo mphamvu ya powertrain.
Koma tsopano zikuwoneka kuti Tesla akuyesera kuti apeze zabwino kwambiri padziko lonse lapansi: injini yamagetsi yokhazikika koma osasowa dziko lapansi.
Waukulu njira NdFeB kwa maginito okhazikika ndi ferrite yosavuta (chitsulo okusayidi, nthawi zambiri ndi kuwonjezera barium kapena strontium).Mutha kupanga maginito okhazikika amphamvu pogwiritsa ntchito maginito ochulukirapo, koma malo mkati mwa rotor ndi ochepa ndipo NdFeBB imatha kupereka maginito ochulukirapo ndi zinthu zochepa.Other okhazikika maginito zipangizo pa msika monga AlNiCo (AlNiCo), amene amachita bwino pa kutentha koma amataya magnetization mosavuta, ndi Samarium Cobalt, wina osowa dziko maginito ofanana NdFeB koma bwino pa kutentha kwambiri.Pali zinthu zina zingapo zomwe zikufufuzidwa, makamaka pofuna kuthetsa kusiyana pakati pa ma ferrite ndi nthaka yosowa, koma izi zikadali mu labu ndipo sizinapangidwebe.
Ndikuganiza kuti Tesla adapeza njira yogwiritsira ntchito rotor yokhala ndi maginito a ferrite.Ngati adachepetsa zomwe zili mu REE, zikutanthauza kuti akuchepetsa kuchuluka kwa maginito okhazikika mu rotor.Ine kubetcherana iwo anaganiza kupeza zochepa kuposa mwachizolowezi flux ku chidutswa chachikulu cha ferrite m'malo kachidutswa kakang'ono NdFeB.Ndikhoza kulakwitsa, mwina adagwiritsa ntchito njira ina pamlingo woyesera.Koma izi zikuwoneka ngati sizingatheke kwa ine - Tesla akufuna kupanga anthu ambiri, zomwe zikutanthauza kuti dziko lapansi losowa kapena ma ferrite.
Pachiwonetsero cha tsiku la Investor, Tesla adawonetsa slide kufanizitsa kugwiritsa ntchito kwapadziko lapansi kosowa mu mota yamaginito ya Model Y yokhala ndi injini ya m'badwo wotsatira:
Tesla sanatchule zomwe adagwiritsa ntchito, mwina akukhulupirira kuti chidziwitsocho ndi chinsinsi chamalonda chomwe sichinafune kuwulula.Koma nambala yoyamba ikhoza kukhala neodymium, yotsalayo ikhoza kukhala dysprosium ndi terbium.
Ponena za injini zamtsogolo - chabwino, sitikutsimikiza kwenikweni.Zithunzi za Tesla zimasonyeza kuti injini ya m'badwo wotsatira idzakhala ndi maginito osatha, koma maginitowo sangagwiritse ntchito dziko lapansi.
Maginito okhazikika a Neodymium akhala akugwiritsidwa ntchito kwanthawi yayitali, koma zida zina zomwe zitha kufufuzidwa pazaka khumi zapitazi kuti zilowe m'malo mwake.Ngakhale Tesla sananene kuti ndi iti yomwe akufuna kugwiritsa ntchito, zikuwoneka kuti yatsala pang'ono kupanga chisankho - kapena akuwona mwayi wopeza yankho labwino posachedwa.
Jameson wakhala akuyendetsa magalimoto amagetsi kuyambira 2009 ndipo wakhala akulemba za magalimoto amagetsi ndi mphamvu zoyera za electrok.co kuyambira 2016.
