Appeal No. 1999-1941
Application No. 08/629,700
the switched reluctance machine in four finite states in
dependence upon the detected current magnitude flowing in the
machine winding during each of the four finite states without
determining machine rotor position. Claim 1 is reproduced below
for further understanding of the invention.
1. A control for a switched reluctance machine having a
machine rotor and a machine winding coupled to a power
converter, comprising:
means for detecting a magnitude of current flowing in the
machine winding; and
means responsive to the detecting means for controlling
commutation of the switched reluctance machine in four
finite states in dependence upon the detected current
magnitude flowing in the machine winding during
each of said four finite states without determining
machine rotor position.
The Examiner relies on the following references:
MacMinn et al. (MacMinn) 4,739,240 Apr. 19,
1988
Lyons et al. (Lyons) 5,140,244 Aug. 18, 1992
Claims 1 to 14 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Lyons in view of MacMinn.
Rather than repeat the arguments of Appellant and the
Examiner, we make reference to the brief and the answer for
their respective details thereof.
