Abstract
A laminated core for an electric machine has at least one cooling duct which runs within the laminated core and can be flowed through by a cooling fluid for cooling the laminated core. The cooling duct has at least one first throughflow opening which can be flowed through by the cooling fluid and penetrates an outer circumferential-side shell face of the laminated core, which shell face points toward the outside in the radial direction of the laminated core. The cooling duct further has at least one second throughflow opening which can be flowed through by the cooling fluid and penetrates an inner circumferential-side shell face of the laminated core, which shell face points toward the inside in the radial direction of the laminated core.
