Abstract

L'invention concerne une bobine électromagnétique comprenant un circuit magnétique, au moins un enroulement disposé autour du circuit magnétique et un caniveau (20) recevant l'enroulement et disposé entre le circuit magnétique et l'enroulement. Afin d'améliorer la dissipation thermique de la bobine, le caniveau (20) est réalisé dans un matériau conducteur de l'électricité et le caniveau (20) comprend une ouverture (22) configurée pour éviter au caniveau (20) de former une spire fermée autour du circuit magnétique.
