Abstract
Embodiments of the invention provide for conical magnets for rotors in electrodynamic machines, methods to design the same, and rotor-stator structures for electrodynamic machines. In various embodiments, a rotor-stator structure for electrodynamic machine can include field pole members and conical magnets. According to at least some embodiments, one or more of the conical magnets can include a magnetic region configured to confront one or more air gaps. The magnetic region can be substantially coextensive with one or more acute angles to the axis of rotation. The magnetic region can also include a surface positioned at multiple radial distances from the axis of rotation in a plane perpendicular to the axis of rotation.
