Appeal No. 2000-2081
Application 08/656,082
Appellants’ invention relates to a method for
constructing a salient pole motor. As noted on pages 2 and 3
of the specification, a salient pole motor differs from an
induction motor having distributed windings (i.e., wherein the
turns of a winding pole are distributed over a predetermined
number of teeth of the stator core, e.g., over three, five or
seven teeth) in that the salient pole motor windings have all
the turns of the motor pole in one winding group spanning a
single tooth of the stator core. Appellants indicate that
salient pole motors find general application as stepper
motors. Independent claims 1, 14, 27, 29 and 30 are
representative of the subject matter on appeal and a copy of
those claims may be found in Appendix I of appellants’ brief
(Paper No. 17).
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
