Abstract: 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 with a corresponding stator assembly. In some embodiments a rotor assembly can include magnetically permeable structures having confronting surfaces oriented at an angle to the axis of rotation. A group of magnetic structures can be interleaved with the magnetically permeable structures. The magnetically permeable structures can also include non-confronting surfaces adjacent to which boost magnets are disposed to enhance flux in a flux path passing through magnetic structures that are interleaved with magnetically permeable structures. Further, the rotor assemblies can include a flux conductor shield disposed adjacent to the boost magnets, the flux conductor shield configured to provide return flux paths.

Abstract: Disclosed are foil coil structures and methods for winding the same for stators in electrodynamic machines, as well as electrodynamic machines that implement such coil structures. In one embodiment, a foil coil structure is configured for implementation with a field pole member having pole faces that confront, for example, conical magnets.

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.

Abstract: Embodiments of various rotor assemblies can include an arrangement of magnetically permeable structures including confronting surfaces oriented at an angle to the centerline, and different subsets of non-confronting surfaces. Different magnets can be disposed adjacent to the different subsets of non-confronting subsets. For example, one type of magnet lies is a flux path or a flux path portion passing through one subset of non-confronting surfaces, and another type of magnet is external to the flux path adjacent to another subset of non-confronting surfaces and is configured to boost the flux associated with the flux path (or a portion thereof). In some embodiments, the magnetic region can include a portion of the internal permanent magnet. One example of a rotor assembly is an outer rotor assembly.

Abstract: 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 each having a portion of a surface that is 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 (e.g., field pole members) having pole faces. A subset of the pole faces can be positioned to confront the arrangement of the magnetic regions to establish air gaps, with the subset of the pole faces being disposed internally to the conically-shaped space.
