Abstract
An electric machine such as a direct current motor or generator in which a stator is formed using a set of electrically conductive blade structures disposed about an inner axis of a stator core. Electrical interconnections between the conductive blades are provided by a set of disks connected to the ends of the blades. The disks are formed preferably from an insulating substrate material having electrically conductive pads formed thereon to provide circuit interconnections between the blades. A desired path for current flow is provided by arranging the blades and conductive pads on the disks appropriately in the desired number of turns and phases. The conductive blades and conductive portions of the interconnect disks are formed, in a preferred embodiment, from a material such as a copper and molybdenum laminate.
