Rotor cooling with thermally conductive material

A rotor core for an electric machine comprises a core stack comprising a plurality of identical laminates, each laminate comprising a plurality of magnet slots formed therein, the magnet slots of each laminate being axially aligned and adapted to support a plurality of permanent magnets therein, and a number of thermally conductive inserts extending axially through the core stack, and adapted to conduct heat outwardly from an interior of the core stack toward a distal end of the core stack. 一种用于电机的转子芯包括芯堆叠，所述芯堆叠包括多个相同的层压板，每个层压板包括形成在其中的多个磁体槽，每个层压板的磁体槽轴向对齐，并适于在其中支撑多个永磁体，和若干个导热插件，所述导热插件轴向延伸穿过所述芯堆叠，并适于将热量从所述芯堆叠的内部向外朝向所述芯堆叠的远端传导。
