Appeal 2006-3366
Application 10/864,041
BACKGROUND
Appellant’s invention relates to a radial airgap, transverse flux motor.
An understanding of the invention can be derived from a reading of
exemplary claim 1, which is reproduced below.
1. A dynamoelectric machine, comprising:
(a) at least one stator assembly, a plurality of stator
windings, and at least one rotor assembly supported for rotation
about a rotational axis, said rotor and stator assemblies being
concentric with said rotational axis;
(b) said at least one rotor assembly comprising at least one
rotor magnet structure, said magnet structure providing
magnetic poles having north and south polarity, said poles
being disposed in at least two rotor layers that are substantially
planar, perpendicular to said rotational axis, and axially spaced
apart, each of said layers having the same number of poles, and
said poles in each of said layers being disposed equiangularly
about the circumference of said rotor assembly on a cylindrical
periphery thereof;
(c) said at least one stator assembly comprising a plurality
of stator cores, each of said stator cores terminating in a first
and a second stator poleface and being comprised of laminated
layers composed of a material selected from the group
consisting of amorphous, nanocrystalline, and flux enhancing
Fe-based metal, said stator cores being disposed equiangularly
about the circumference of said stator assembly, such that:
(i) said first and second stator polefaces of each of said
stator cores are situated on a cylindrical periphery of said stator
assembly in axial alignment;
(ii) said first stator polefaces are in a first stator layer
radially adjacent one of said rotor layers; and
(iii) said second stator polefaces are in a second stator layer
adjacent another of said rotor layers; and
