Krútiaci moment (Nm)

GlossaryElectromobilesKrútiaci moment (Nm)

Krútiaci moment (uvádza sa v Nm) je v prípade elektromobilov úzko previazaný s výkonom, pre dynamiku vozidla však nie je taký zásadný ako pri vozidlách so spaľovacím motorom. Elektrické motory totiž zhruba do tretiny celkového rozsahu otáčok pracujú na maxime krútiaceho momentu, ktorý potom len mierne klesá. V dôsledku toho majú elektromobily aj v nízkych rýchlostiach veľmi veľkú ťažnú silu a zrýchlenie.

Krútiaci moment však pre dynamiku elektromobilov nie je taký zásadný, ako samotný výkon. V mnohých prípadoch je jeho uvádzanie do istej miery len marketingový údaj, ktorý bez ďalších informácií napríklad o sprevodovaní nemá o rýchlosti a dynamike automobilu prílišnú vypovedajúcu hodnotu. Dôvod je okrem iného ten, že elektromotory zhruba do tretiny celkového rozsahu otáčok pracujú na maxime krútiaceho momentu, ktorý potom len mierne klesá. V dôsledku toho majú elektromobily aj v nízkych rýchlostiach veľmi veľkú ťažnú silu a zrýchlenie.
