Abstract
(EN)
The present invention relates to a brushless DC motor core using a hybrid composite containing aluminum, a multi-walled carbon nanotube, iron, and cobalt, whereby a hybrid composite, which has a low weight and high-performance magnetic core and can be manufactured in various forms, is usable in place of a heavy standard laminate core of a BLDC motor, and a brushless DC motor including a core made of the above-mentioned low weight hybrid composite can be provided in a driving means, such as a vehicle and an electric bicycle, and a flying means, such as a drone, so as to enhance the efficiency of the driving means and the flying means.
(FR)
La présente invention concerne un noyau de moteur à courant continu sans balai utilisant un composite hybride contenant de l'aluminium, un nanotube de carbone à parois multiples, du fer et du cobalt, ce par quoi un composite hybride, qui a un noyau magnétique à faible poids et à haute performance et qui peut être fabriqué sous diverses formes, peut être utilisé à la place d'un noyau stratifié standard lourd d'un moteur BLDC, et un moteur à courant continu sans balai comprenant un noyau constitué du composite hybride de faible poids mentionné ci-dessus peut être disposé dans un moyen d'entraînement, tel qu'un véhicule et une bicyclette électrique, et un moyen volant, tel qu'un drone, de façon à améliorer l'efficacité du moyen d'entraînement et du moyen volant.
