Appeal No. 2006-1880
Application No. 10/064,363
Invention
Appellants’ invention relates to an armature for a revolving
field electrical machine and more particularly to an improved
armature construction that permits winding to a maximum density
and a simplified winding method.
Claim 1 is representative of the claimed invention and is
reproduced as follows:
1. An armature for a rotating machine having a circular
core of a magnetic material and a plurality of magnetic pole
teeth extending radially from said circular core and terminating
at terminal ends spaced from said circular core, each of said
magnetic pole teeth defining a core and an enlargement formed at
the terminal end of said core, to define slots formed between
adjacent magnetic pole teeth, each of said slots having a mouth
formed between adjacent enlargements, an insulating bobbin having
a circular portion lying on one side of said circular core and
leg portions that extend for the length of said pole teeth at
least on the sides of said slots and insulator extending portions
extending at least along the side of said enlargements facing
said circular core and defining a fixed and open clearance slot
therebetween for protecting windings formed by a winding needle
from damage by the winding needle and for forming a fixed
clearance opening to receive at least a portion of the winding
needle.
