Abstract
(EN)
A motor according to an aspect of the present invention is provided with: a rotor rotatable about a center axis; a stator radially facing the rotor with a gap therebetween; and a stator holding member that holds the stator. The stator holding member has a plurality of outer fins provided on the outer surface of the stator holding member. At least a portion of the plurality of outer fins has a lattice structure.
(FR)
Un moteur selon un aspect de la présente invention comprend : un rotor pouvant tourner autour d'un axe central; un stator faisant radialement face au rotor avec un espace entre eux; et un élément de maintien de stator qui maintient le stator. L'élément de maintien de stator comporte une pluralité d'ailettes externes disposées sur la surface externe de l'élément de maintien de stator. Au moins une partie de la pluralité d'ailettes externes a une structure en treillis.
