Appeal 2007-2463
Application 10/403,555
STATEMENT OF THE CASE
Appellant invented a rotor structure for an electric motor that ensures
that a bandage wrapped around the rotor core assembly is securely attached.
In particular, a securing ring is disposed radially over the edge of the
bandage to substantially extend flush with the bandage.1 Claim 1 is
illustrative with the key limitation in dispute emphasized:
1. A rotor structure for an electric motor, comprising:
a cylindrical rotor core assembly having an end surface face;
a plurality of permanent magnets disposed on an outer circumference
of the rotor core assembly;
a bandage wrapped around the rotor core assembly to secure the
permanent magnets in place, said bandage having a bandage edge arranged
in proximity of the end surface of the rotor core assembly; and
a securing ring disposed radially over the bandage edge such as to
substantially extend flush with the bandage and to hold the bandage against
the rotor core assembly.
The Examiner relies on the following prior art references to show
unpatentability:
