Appeal No. 2006-0859
Application No. 09/778,338
Findings of Fact
1. Appellants’ specification does not contain drawings directed to the
structure of Appellants’ claims 7 and 9-11.
2. Appellants’ specification does contain a drawing (Fig. 6) directed to the
properties of Appellants’ claims 7 and 9-11.
3. Appellants’ figure 2 shows the relationship of the armature poles (31) on
the stator (12) and the permanent magnets (22) in the rotating machine.
4. Fig. 2 shows twelve magnets of alternating polarity.
5. One rotation of the machine produces six complete alternating current
cycles of 360 electrical degrees each.
6. Each pair of adjacent magnets generates one complete AC cycle of 360
electrical degrees, i.e., has an electrical angle of 360 degrees. Thus, each magnet has
an electrical angle of 180 electrical degrees.
7. Each magnet physically occupies a mechanical angle of 30 degrees.
8. Each magnet has a magnetization angle between 0 and 30 mechanical
degrees depending on how much of the center of the magnet is magnetized.
9. Each magnet has a magnetization angle between 0 and 180 electrical
degrees depending on how much of the center of the magnet is magnetized.
10. Fig. 7 shows the properties of a rotating machine having twelve magnets
based on the mechanical angle values in the first column. Column 1 of Fig. 7 compared
to column 2 shows that one mechanical degree equal six electrical degrees, e.g. 135 in
column 2 divided by 22.5 in column 1. Thus, each magnet (180 electrical degrees)
