Patent ID: 7843104

Claim:
A stator adapted for use in combination with a rotor in a dynamoelectric machine such that alternating magnetic fields are induced in the stator, the stator comprising: magnetic sheets oriented approximately perpendicular to an axis of the stator, and stator windings passing through the magnetic sheets in a direction approximately parallel to the axis of the stator; and means for axially compressing the magnetic sheets of the stator together, the compressing means being formed of a ductile iron alloy containing, by weight, about 3.25 to about 3.40% carbon, about 3.70 to about 3.80% silicon, about 4.50 to about 4.70% nickel, up to about 0.20% manganese, up to about 0.06% magnesium, less than 0.02% phosphorus, less than 0.02% sulfur, with the balance being iron and incidental impurities, wherein the ductile iron alloy exhibits a resistivity of at least 70 μ-ohm·cm and a maximum permeability of at least 500H/m and the compressing means exhibits properties that inhibit joule heating of the component by eddy currents induced by alternating magnetic fields of the stator.
