Abstract
A rotor structure for a conical air gap electrodynamic machine has one or more rotor assemblies arranged on an axis of rotation. Each of the one or more rotor assemblies includes magnetically permeable structures positioned radially about the axis of rotation. The magnetically permeable structures include first surfaces confronting the conical air gap that are oriented at an angle to the axis of rotation and second adjacent surfaces that are at an angle to the axis of rotation. The second adjacent surfaces are disposed radially closer to the axis of rotation than the first surfaces. One or more groups of magnetic structures include magnetic material. The one or more groups of magnetic structures include a first group of magnetic structures interleaved with the magnetically permeable structures, a second group of magnetic structures, and a flux conductor shield disposed adjacent to the second group of magnetic structures.
