Their application in switch electrical contact and electrical brush shows that the properties and service life of these composite were improved apparently by adding carbon fiber. 结果表明,碳纤维的加入明显改善了复合材料的性能,其使用寿命大幅度提高。
Our country motocycle electrical machinery is the brush 我国摩托车电机用电刷市场
Application and choice of electrical brush for rolling mill 轧钢机用电刷的应用与选择
In this paper, running of the reverser, criteria of good rectification, maintenance of reverser, utilization and maintenance of the electrical brush, common fault of DC motor and it's processing methods are described. 论述了换向器运行及良好整流的标准,换向器的保养,电刷的使用和维护,换向器和电刷常见故障及处理方法。
This text discussed in base carbon black electrical brush research to manufacture the adoption half repairs the strong carbon black as the framework; 讨论了在炭黑基电刷研制中采用半补强炭黑作骨架材料,改性高温沥青作粘结剂;
Somewhat search after of the wear for machine electrical brush 电机用电刷磨损机理的几点探索
To eliminate the radial pressure imposed on the rotated shaft by the carbon brush and realize good electrical Conductibility, the symmetrical double carbon brush is adopted in the system. 采用对称碳刷设计进行旋转工具电极引电,消除碳刷对旋转轴的径向压力,保证引电可靠;
On the basis of its inherent electrical physical behaviour of the traction machine brush with high properties, the technolagy ways to prepare the brush with high properties were gived. 阐述了高性能牵引电刷所固有的电气物理特性,据此提出了制造高性能牵引电机用电刷的工艺方案。
The results showed that, during electrical wear process, the contact voltage drop of both positive and negative brushes had the same trend: be stable after first increase, and the contact voltage of negative brush was always bigger than positive brush. 研究发现,在电磨损过程中,正负电刷接触电压降变化趋势相同&先上升然后趋于稳定,且负刷的接触电压降大于正刷的接触电压降。
This paper provides an wear formula in case of electrical current carrying under the theory of finite element theory, while establishing a motor brush wear rate used to query the database. 对于电刷磨损问题,本文根据有限元理论和磨损理论提出了载流情况下的电磨损率计算公式,同时建立了电机常用电刷磨损率的数据库以便查询。
The brushless DC motor ( BLDC), with the electrical circuit to replace the mechanical brush and the commutator, is one of the most high effective motor currently for combining the advantages of both AC motor and DC motor. 无刷直流电机以电子控制线路代替机械电刷和换向器实现直流电机的换相,集有刷直流电机和交流电机的优点于一体,是当今最高效率的调速电机。
