Appeal No. 2006-0859
Application No. 09/778,338
0.65 mm. The plurality of steel plates are interlocked relative to each other by a series
of partially punched openings. The magnetization angle of the pole of each of the
plurality of permanent magnets is set with respect to the rotational axis to be in an
electrical range of 120-140 degrees.
Claims 1, 2, and 7, are representative of the claimed invention and are
reproduced as follows:
1. A rotating machine having a plurality of permanent magnets having alternating
polarities in a circumferential direction at equally spaced intervals and a relatively
rotatable associated element having a plurality of armatures around which coil windings
are formed, the armatures are formed from a lamination of a plurality of electromagnetic
steel plates each having a thickness in the range of 0.25 – 0.65mm.
2. A rotating machine as set forth in claim 1 wherein the electromagnetic steel
plates are interlocked relative to each other by series of partially punched openings
forming holes and projections, which inter-fit with each other so as to line up the
electromagnetic steel plates in relationship to each other and to provide a mechanical
coupling there between.
7. A rotating machine as set forth in claim 1 wherein the spacing of the poles of said
permanent magnets and their number and the number and spacing of the coils being
set so that if the degree of rotation during which each coil experiences a complete cycle
of electrical current is taken as 360° the circumferential extent of each of the magnet
poles (the magnet electrical angle) lies in the range of 120° to 140° of such relative
rotation.
