    Abstract: Simple to manufacture electric generators or motors and methods of manufacturing such are disclosed. Such devices are preferably manufactured from 2-dimensionally cut, flat stock materiel. The generator or motor has two large diameter rotors to enable, for example, useful generation of electricity at low revolutions per minute. The frame of the generator includes stators sidewalls with castellations on the periphery of the walls. Castellated end plates removably interlock with the stators. The rotors drive magnets past the stators in the frame of the device. In preferred embodiments, rotors are driven by human legs or arms, low speed wind, or water with low or zero water drop distance.

    Abstract: A stator includes an armature core having an annular shape, coils, and an insulator. The coils are arranged along the armature core. Each of the coils is a wound conductive winding. Each of the coils includes a pair of facing portions disposed to be aligned in a circumferential direction with a predetermined interval therebetween. The first and second facing portions of each of the coils constitute intermediate portions of the corresponding one of the coils. Each of the coils includes a pair of first and second coil end portions that link the facing portions to each other. The insulator is arranged between the stator core and the coils. The insulator includes a base comprised of an insulating material, and one or more soft-magnetic members each being comprised of a soft-magnetic material, the one or more soft-magnetic members being contained in the base.

    Abstract: An additively manufactured air gap winding for an electrical machine is provided. The air-gap winding includes a hollow cylindrical main portion having a geometric axis, the main portion defining an active winding length of the winding, and electrical winding conductors of the winding extending in the main portion from a first axial end of the winding to a second axial end. The air gap winding further comprises a first winding head at the first axial end and a second winding head at the second axial end, wherein winding head connections of the winding conductors extend in the winding heads. The winding heads project radially inwardly and/or outwardly beyond the hollow cylindrical main section. The winding head connections extend at least in sections at different distances from the axis in such a way that one winding head connection at least partially radially surrounds the other winding head connection.

    Abstract: The rotating electric machine includes a stator having a stator winding and a rotor facing the stator in a radial direction. The rotor includes a carrier having a disk-shaped end plate section fixed to a rotating shaft and arranged coaxially with the rotating shaft, and an annular magnet unit arranged coaxially with the rotating shaft. The magnet has a cylindrical magnet holder whose one end in an axial direction is fixed to the end plate section, and a magnet fixed to a peripheral surface on a stator side in the radial direction in the magnet holder and having an alternating polarity in a circumferential direction. The magnet holder is made of a non-magnetic material. In the magnet, an orientation of an axis of easy magnetization on a q-axis is deviated from an orientation parallel to the q-axis.
