ROTOR-STATOR STRUCTURES WITH AN OUTER ROTOR FOR ELECTRODYNAMIC MACHINES

摘要

Various embodiments relate generally to electrodynamic machines and the like, and more particularly, to rotor assemblies and rotor-stator structures for electrodynamic machines, including, but not limited to, outer rotor assemblies and/or inner rotor assemblies. In some embodiments, a rotor-stator structure includes a rotor structure in which rotor assemblies are arranged on an axis of rotation. A rotor assembly can include an arrangement of magnetic regions having a portion of a surface oriented substantially at an angle to the axis and disposed externally to, for example, a portion of a conically-shaped space centered on the axis of rotation. The rotor-stator structure also can include pole members having pole faces. A subset of the pole faces can be positioned to establish air gaps, with the subset of the pole faces being disposed internally to the conically-shaped space.
