- Tu et al, US 2004/0135452 discloses a flat rotary electric generator that includes at least one toroidal coil structure for cutting magnetic lines to induce a current and at least one disc-shaped magnetic pole structure oriented parallel to the helical coil structure. If multiple toroidal coil structures and disc-shaped magnetic coil structures are included, the toroidal coil structures and disc-shaped magnetic coil structures are arranged in alternating manner. The toroidal coil structure and disc-shaped magnetic pole structure are not provided with a permeable material. When either the toroidal coil structures or the at least one disc-shaped magnetic pole structure is rotated by an external force, the toroidal coil structure cuts the magnetic lines passing therethrough to generate an induced current.

- a plurality of magnetic fields is created when electrical current is conducted through wire wound around poles on the toroidal core.
- a monolithic body of phase change material substantially encapsulates the conductors and holds the stator arc segments in contact with each other in the toroidal core.

Reversal of the current flow results in a reversal of the torque and rotation of the rotor in the opposite direction.

- FIG. 11 shows the coil 110 detached from the coil housing 100 and shows, too, coilform 120 upon which coil 110 is wound.
- coil 110 is wound with common insulated wire 112 , however, coil 110 may also be wound with metal strip wherein such strip would have a thickness approximately equal to the diameter of wire 112 and a width W equal to the width of coil 110 , or of the ferromagnetic housing cell's width as shown in FIG. 11 . It is noticed that coil 110 has an axis 114 of the windings that is positioned tangential to the direction of rotation of the electromagnetic field of this machine when the coil is mounted within the coil housing 120 100. This may be best seen in FIG.
- coil 110 is shown mounted within coil housing 120 100, and housing 120 100 is shown in its mounted position on ring 30 A Only two coil housings 120 100 are shown in the figures, but in the completely assembled machine, the coil housings 120 100 form a full circle around tubular axle 110 10.

- FIGS. 18 - 20 show an alternative embodiment of coil 110 .
- Previously coil 110 was described as constructed by windings of common insulated electrical conductor wire 112 as is well known in the art, and alternatively using flexible insulated conductive metal strip stock. However, it has been discovered that coil 110 may also be advantageously constructed from a solid block of conductive metal.
- FIG. 18 is shown a schematic diagram of such a coil 110 wherein the lines 110 A represent conductive paths and the spaces between the lines represent material that is cut away from the solid block of conductive metal. This may be accomplished using electrical discharge machining, also known by the acronym EDM.
- EDM is used to cut into the solid block of electrically conductive material such as copper, aluminumor, steel, but most preferably, or iron, and the cuts are directed as shown in FIG. 18 .
- the solid block has been reduced to a single coil where the coil's windings are strips having the desired width W ( FIG. 19 ), i.e., the width of the original solid block.
- FIG. 19 shows the cut block in perspective with plus (+) and minus ( ⁇ ) electrodes attached for connecting the coil 110 into a circuit of the present machine.
- FIG. 20 shows the same cut block as FIG. 19 , but partially cut-away to better illustrate the layers of the windings.
- no space is shown separating the windings, however, these figures are conceptual diagrams where the spaces between adjacent windings are considerably less wide than the windings themselves, and the spaces may be filled with an electrical insulator using an electro-chemical process such as electroplating.
- the coil housing 100 may also be advantageously constructed in the same manner as the coil shown in FIGS.
- the housing 100 may be sectioned using EDM to establish a coil-like configuration while maintaining the housing in the form shown in FIGS. 8 - 12 .
- the establishment of coil 110 and coil housing 100 in the above manner provide significant advantages including low eddy current loss, less resistance to AC and to DC current flow, and smaller size.
