Soft magnetic amorphous electromechanical component and method making the same
A three dimensional soft magnetic metal mass suitable for milling is formed wrapping soft magnetic metal ribbon into a three dimensional shape and then applying adhesive to the three dimensional shape. The adhesive permeates the three dimensional shape. The adhesive is then cured. If the soft magnetic metal mass is made as a toroid, then it could be processed into an electro-mechanical component. The electro-mechanical component would then be suitable for use in very high frequency electric motors.
