Northrop Grumman, m'modzi mwa zimphona zankhondo zaku US, adayesa bwino injini yamagetsi yamphamvu kwambiri ku US Navy, yoyamba padziko lonse lapansi ya 36.5-megawatt (49,000-hp) high-temperature superconductor (HTS) ship propulsion electric motor, kuwirikiza kawiri kuposa zolemba zoyesa mphamvu za US Navy.
Galimotoyi imagwiritsa ntchito mawaya otenthetsera kwambiri, ndipo mphamvu yake yolemetsa ndi kuwirikiza ka 150 kuposa mawaya amkuwa ofanana, omwe ndi osakwana theka la ma motor wamba.Izi zidzathandiza kuti zombo zatsopanozi zikhale zowonda mafuta komanso kumasula malo owonjezera mphamvu zankhondo.
Dongosololi linapangidwa ndikumangidwa pansi pa mgwirizano wa US Office of Naval Research kuti awonetse mphamvu ya ma motors otenthetsera kwambiri ngati ukadaulo wotsogola wa zombo zapamadzi zonse zapamadzi zam'madzi zam'madzi ndi sitima zapamadzi zam'tsogolo.Naval Sea Systems Command (NAVSEA) idapereka ndalama ndikuwongolera kuyesa bwino kwa mota yamagetsi.
US Navy yaika ndalama zoposa $ 100 miliyoni pakupanga ukadaulo wapamwamba kwambiri wotentha kwambiri, ndikutsegulira njira osati zombo zapamadzi zokha, komanso zombo zamalonda, monga akasinja ndi akasinja amafuta achilengedwe (LNG), omwe amathanso kugwiritsa ntchito Space. ndi phindu logwira ntchito la injini zotentha kwambiri za superconducting.
Mayesero a katundu amasonyeza momwe galimotoyo imachitira pansi pa kupsinjika maganizo ndi momwe zimagwirira ntchito pamene ikuyendetsa chombo panyanja.Gawo lomaliza lachitukuko chagalimoto limapereka mainjiniya ndi ophatikiza oyendetsa panyanja chidziwitso chofunikira pazosankha zamapangidwe ndi mawonekedwe ogwiritsira ntchito injini yatsopano ya superconductor.
Makamaka, injini yotentha kwambiri yopangidwa ndi AMSC sinasinthe kwambiri malinga ndiukadaulo wamagalimoto oyambira.Makinawa amagwira ntchito mofanana ndi makina wamba amagetsi, amapeza ubwino wawo wochuluka posintha ma coil a rotor a mkuwa ndi kutentha kwambiri kwapamwamba kwambiri.Ma rotor a HTS amathamanga "ozizira," kupewa kupsinjika kwamafuta komwe ma motor wamba amakumana nawo akamagwira ntchito bwino.
Kulephera kukwaniritsa kasamalidwe koyenera ka kutentha kwakhala vuto lalikulu popanga ma mota amagetsi amphamvu, okwera kwambiri omwe amafunikira kuti agwiritse ntchito panyanja ndi malonda apanyanja.M'ma motors ena apamwamba kwambiri, kupsinjika komwe kumachitika chifukwa cha kutentha nthawi zambiri kumafuna kukonzanso ndi kukonzanso magalimoto okwera mtengo.
Galimoto ya 36.5 MW (49,000 hp) HTS imazungulira pa 120 rpm ndipo imapanga 2.9 miliyoni Nm ya torque.Galimotoyo idapangidwa kuti izithandizira m'badwo wotsatira wa zombo zankhondo ku US Navy.Ma motors amagetsi a kukula uku amakhalanso ndi ntchito zamalonda zachindunji pa sitima zazikulu zapamadzi ndi zombo zamalonda.Mwachitsanzo, ma injini awiri wamba a 44 MW amagwiritsidwa ntchito poyendetsa sitima yapamadzi yotchuka ya Elizabeth 2.Ma motors amalemera matani oposa 400 iliyonse, ndipo 36.5-megawatt HTS yamagetsi yamagetsi imalemera pafupifupi matani 75.
