Abstract

La présente invention se rapporte à un moteur multirotatif qui utilise un noyau de moulage en trois dimensions (3D). Particulièrement, le moteur multirotatif qui utilise le noyau de moulage en 3D comprend : un premier rotor ; un premier stator disposé dans le premier rotor ; un deuxième rotor disposé dans le premier stator ; un deuxième stator disposé dans le deuxième rotor ; un troisième rotor disposé dans le troisième stator ; et un arbre disposé dans le troisième rotor. Au moins un noyau de stator du premier stator et du deuxième stator peut être moulé en une forme en 3D par compression d'un matériau pulvérulent afin de réduire le volume du moteur. De plus, le noyau du moteur peut être facilement fabriqué afin de simplifier le procédé de fabrication du moteur.
