我省乐山县第一农具厂1959年3月试用“牛皮纸粘铁粉片”代替矽钢片,制成一台4.5瓩三相感应电动机。经过带动鼓风机较长时间使用证明良好。又制成一台同样规格的电动机,并着手制造一台10瓩三相交流同步发电机。现将该厂制成的4.5瓩的电动机的设计、制造,以及试验结果,分别介绍于下,以供大家研究、参考。电动机的制造一、牛皮纸粘铁粉(1)使用原材料:0.25毫米厚的牛皮纸25张,生铁粉30公斤(灰口铁、白口铁均可),精胶100市两,白矾2.5两,红矾2.5两,甘油95毫升(西西)。生铁粉可利用车床车下来的或锉刀锉下来的铁屑,越细越好,最好是过筛。
Leshan County, the first farm machinery factory in March 1959 trial “kraft paper sticky iron tablets” instead of silicon steel, made of a 4.5 瓩 three-phase induction motor. After a long time to drive the use of the blower to prove good. And made of a motor of the same specifications, and set out to create a 10 瓩 three-phase AC synchronous generator. Now the plant made of 4.5 瓩 motor design, manufacture, and test results, respectively, introduced below, for your study, reference. Motor manufacturing a Kraft iron sticky powder (1) the use of raw materials: 0.25 mm thick kraft paper 25, 30 kg of pig iron (gray iron, white iron can be), 100 two fine plastic, alum 2.5 two, red Alum 2.5 two, 95 ml of glycerin (West). Pig iron powder can be used down or file rasp down the iron filings, the more detailed the better, it is best sifted.
