Abstract
An electromagnetic component is formed from a pre-form comprising layers of soft magnetic metal ribbon. Adhesive is applied to permeate the pre-form and is then cured. The bonded pre-form is placed within a milling assembly that supports and constrains the ribbon layers during a milling operation used to process the pre-form into an electromagnetic component shape. Optionally, the shape is thermally processed. The resulting electromechanical component has attractive soft magnetic properties, including low core loss, that render it useful as a component in electric motors and generators and static inductive devices operable at high excitation frequencies.
