Method of making soft magnetic amorphous metal electromechanical component |
摘要 |
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 electromechanical component. The electro-mechanical component would then be suitable for use in very high frequency electric motors. |

1. A method for forming a three dimensional soft magnetic metal mass suitable for milling, comprising the steps of:
winding a commercially produced soft magnetic metal ribbon on an inner ring placed on a winding plate into a toroid having three dimensional shape; removing said wound toroid from said winding plate and applying a liquid adhesive allowing permeation of said liquid adhesive; curing said wound toroid with said liquid adhesive at an adhesive curing temperature; placing said adhesive bonded wound toroid in a milling assembly comprising an inner containment bottom hat and an outer containment hat, said outer containment hat having a plurality of slots for the passage of a milling cutter; milling slots in said adhesive bonded toroid; removing the milled adhesive bonded toroid from said milling assembly; and thermally processing said milling assembly with said adhesive bonded milled toroid at a temperature relieving milling stresses and enhancing magnetic properties. |
