Method of manufacturing an electromagnetic core |
摘要 |
A method of manufacturing stationary electromagnetic cores utilizes mild steel having a carbon content of up to 0.01% by weight and an impurity content of less than 0.31% by weight. Use of this material lowers the cost of manufacturing electromagnetic cores by shortening the drawing process and obviating the necessity for magnetic annealing.
