直流电机用碳纤维电刷的研发及应用

Development and application of carbon fiber brush for DC motor

当前电刷产品均持原状甚至有"每况愈下"之嫌,整个电刷行业也冠以"夕阳工业"之说,关键的直流电机用高端电刷仍大部分由国外电刷维系。国外电碳企业,无论是质量还是总量,至今仍有较大的优势,我们尚有努力赶超之必要。采用碳纤维粉及造孔剂,提高直流电机用电刷材料的耐磨性及各向异性,达到改善电刷的换向性能及使用寿命。本文就直流电机用电刷进行分析、研发,以期引起同行的关注,激发电碳行业同仁的重视。

The electrical carbon brush products to undisturbed and even a ＂ situation g from bad to worse＂ too, the brush industry also dubbed the ＂sunset industry＂ said .For key DC motors, most of the high-end brushes are still held by foreign brushes. Foreign carbon enterprises, whether quality or quantity, still have great advantages, and we still have the necessary to strive to catch up .The use of carbon fiber powder and pore forming agent, improve the wear resistance and the anisotropy of brush materials to improve the performance of DC motor, reversing the brush and the service life. In this paper, DC motor brush for analysis, research and development, in order to attract attention, to stimulate electrical carbon industry colleagues attention.
