Abstract
A magnetic armature, having an outer ring formed of a first powdered metal, the outer ring having magnetic qualities and the first powdered metal of the outer ring includes metals having poor welding characteristics; an inner ring formed of a second powdered metal and being disposed within the outer ring, the inner ring being an iron metal having good welding characteristics and the inner ring defines an inner opening for receiving a shaft for rotating the magnetic armature; wherein said outer ring and said inner ring are joined together by a sintering process and the shaft is welded to the inner ring.
Claims21
A magnetic armature, comprising:
- an outer ring formed of a first powdered metal, said outer ring having magnetic qualities and said first powdered metal of said outer ring comprising metals having poor welding characteristics;
- an inner ring formed of a second powdered metal and being disposed within said outer ring, said inner ring comprising a pure iron metal having good welding characteristics and said inner ring defining an inner opening configured for receiving a shaft for rotating the magnetic armature;
- wherein said outer ring and said inner ring are joined together by a sintering process.
A magnetic armature, comprising:
- an outer ring formed of a first powdered metal, said outer ring having magnetic qualities and said first powdered metal of said outer ring comprising metals having poor welding characteristics;
- an inner ring formed of a second metal and being disposed within said outer ring, said inner ring comprising a pure iron metal having good welding characteristics and said inner ring defining an inner opening configured for receiving a shaft for rotating the magnetic armature;
- wherein said outer ring and said inner ring are joined together by a sintering process.
A magnetic armature, comprising:
- an outer ring formed of a first metal, said outer ring having magnetic qualities and said first metal of said outer ring comprising metals having poor welding characteristics;
