Běžné automobilové elektromotory dosahují poměru výkonu k hmotnosti 2 až 4 kW/kg. Vědci z institutu Fraunhofer IISB však tuto hodnotu výrazně překonali. Nový letecký synchronní motor s permanentními magnety dosahuje až 8 kW/kg.

Při váze 94 kilogramů dokáže vyvinout výkon 750 kilowattů (tedy zhruba 1000 koní) a má krouticí moment 350 Nm, což přibližně odpovídá síle menšího turbovrtulového motoru. Agregát je dlouhý pouhých 60 centimetrů a jeho průměr činí 25 centimetrů.

Volunteering at school. Pencil sharpener wasn’t spinning. Brought home. Took apart and saw that white gear was slipping back out of contact. Put collar on shaft to maintain gear position. I suppose super glue could’ve worked. Hopefully uneven weight doesn’t wear out motor. #electricmotor #diy #mechanical #handyman #gears
