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: An electrical rotating machine having a stator or a rotor with a core that includes a plurality of tapered pole pieces is a low loss electrical machine that results in improvements such as higher output power, higher torque and higher efficiency than a machine that does not have tapered pole pieces. The stator or the rotor with tapered pole pieces may be applied to a power train in automobiles, power tools, and various appliances. The core is constructed by winding an iron-based amorphous magnetic alloy ribbon to form a cylinder-shaped core, then heating, impregnating with resin, and machining by cutting the cylinder-shaped core to form a plurality of tapered pole pieces being separated in an alternating manner by a plurality of slots. The cores having an outside diameter of 50 mm-1200 mm, a tapered angle of 10°-45°, and a slot depth of 10 mm-210 mm are advantageous.

Abstract: A rotary electric machine includes a rotor, a stator having coils wound to surround the rotor, a cylindrical ring member fixedly mounted on the stator by shrinkage fitting, and a frame disposed on the outside of the ring member with a gap created in between. The distance of the gap varies as a result of thermal expansion of the stator and the ring member. An outer surface of the ring member goes into contact with the frame when the stator and the ring member thermally expand, whereby the stator and the ring member are efficiently cooled.
