Appeal No. 1997-2808
Application No. 08/313,129
DECISION ON APPEAL
This is a decision on appeal from the final
rejection of claims 2 through 15. Claim 1 was canceled by an
amendment, paper no. 10.
The invention relates to a multi-phase hybrid
stepping motor. In particular, looking at Figure 3, we see
that the invention has a motor stator with 10 magnetic poles.
The stator has a first set of magnetic poles each having 5
teeth. A second set of magnetic poles, each having 4 teeth,
is alternately disposed between the first set of magnetic
poles.
Representative independent claim 15 is reproduced as
follows:
15. A multi-phase hybrid type stepping motor
including a rotor having a plurality of rotor teeth disposed
about a perimeter thereof and a stator encircling said rotor,
said stator comprising:
a first plurality of magnetic poles, each including
a first predetermined number of teeth; and
a second plurality of magnetic poles alternately
