Appeal No. 2005-0648
Application No. 09/824,980
core 120 and winding wire 124 wound around the stator segment
core, wherein the switched reluctance motor further includes a
rotor 116 defining a plurality of rotor poles 156 and a drive
circuit 56 that energizes the winding wire around the stator
segment assemblies based on a rotational position of the rotor.
This appealed subject matter is adequately represented by
independent claim 1 which reads as follows:
1. An electric power steering system for a vehicle
comprising:
a steering wheel;
a steering shaft connected to said steering wheel;
and
a switched reluctance motor coupled to said steering
shaft for reducing driver effort that is required to turn
said steering wheel, wherein said switched reluctance motor
includes a stator including a plurality of
circumferentially-spaced stator segment assemblies that
include a stack of stator plates forming a stator segment
core and winding wire wound around said stator segment core,
a rotor defining a plurality of rotor poles, wherein said
rotor tends to rotate relative to said stator to maximize
the inductance of an energized winding, and a drive circuit
that energizes said winding wire around said stator segment
assemblies based on a rotational position of said rotor.
The prior art set forth below is relied upon by the examiner
as evidence of obviousness.
