5.制作工艺关于环形铁芯变压器的制作方法,在《提高交流电阻焊机输出电流的方法》一文中已提及,现再作一些补充。用带状硅钢片绕铁芯时,先要做一个木头芯子,如图3所示。图中φ_1、φ_2及φ_3的尺寸可按所卷的环形铁芯内径来确定。b_1、b_2、b_3尺寸可根据硅钢带的宽度而定。由于卷制每一种直径的环形铁芯时,还得加上一块或两块档板,所以b的尺寸必须考虑硅钢 5. Production process On the production of toroidal iron core transformer, in the “AC resistance welding machine to increase the output current method” has been mentioned in the article, now make some supplements. Use ribbon silicon steel around the core, the first to do a wood core, as shown in Figure 3. The size of φ_1, φ_2 and φ_3 in the picture can be determined according to the inner diameter of the toroidal core. b_1, b_2, b_3 size according to the width of silicon steel strip may be. Due to the winding of each diameter of the toroidal core, you have to add one or two baffles, b size must consider the silicon steel
