(1) Le temps de réponse et la bande passante sont influencés par la charge et l'inertie. Les valeurs indiquées sont des valeurs
limites.
(2) Cette valeur ne tient pas compte des pertes dans le fer, des pertes mécaniques ni du couple résistant dû à l'interaction des
aimants permanents. Avec adaptation de résistance rotorique (Rr) validée.
