Abstract
Abstract The invention relates to a linearly moving or rotated flat armature for motors and pulling magnets, comprising a carrier of plastics or of ceramics and a coil system placed on this carrier. The flat armature according to the invention has a carrier which contains 2 to 50% by weight of a mild magnetic substance distributed therein homogeneously. The flat armature according to the invention makes possible an increase of the efficiency of the motor or of the pulling magnet at identical dimensions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
91 words
A linearly moving or rotated flat armature for motors or pulling magnets, comprising a carrier of plastics or of ceramics and a coil system placed on this carrier, characterized in that said carrier contains 2 to 50% by weight of a mild magnetic substance distributed therein homogeneously, said mild magnetic substance having a permeability of 10,000-100,000 μ and a coercive force of 0.015-1 Oe, said carrier being a flat sheet, and said coil system comprising at least one thin layer of conductive material on at least one side of said carrier.
Claim 2
Dependent Claim
91 words
A linearly moving or rotated flat armature for motors or pulling magnets, comprising a carrier of plastics or of ceramics and a coil system placed on this carrier, characterized in that said carrier contains 2 to 50% by weight of a mild magnetic substance distributed therein homogeneously, said mild magnetic substance having a permeability of 10,000-100,000 μ and a coercive force of 0.015-1 Oe, said carrier being a flat sheet, and said coil system comprising at least one thin layer of conductive material on at least one side of said carrier.
Claim 3
Dependent Claim
23 words
A flat armature as claimed in claim 1, in which the carrier contains 10 to 18% by weight of said mild magnetic substance.
Claim 4
Dependent Claim
24 words
