电刷半成品的技术性能和加工成为电刷的运行性能给研究各种牌号电刷提供了足够的资料。诸如每种电刷的电阻系数、抗压强度、弹性模数,成对电刷的瞬变电压降,摩擦系数和磨损的额定值等。 同时列出了超出上述性能的额定范围内的波动技术数据。用整流性能值来说明某些黑色电刷的整流性能。如果能由评定某些电刷性能到查明电刷性能变化的一般规律的话,那末所列资料的重要性就可大大提高。在解决这一任务时非常重要的是正确选择研究性能变化规律性的指数。
Brush half-finished technical performance and processing into a brush running performance for the study of all grades brushes provided sufficient information. Such as the resistivity of each brush, compressive strength, modulus of elasticity, transient voltage drop of brush pairs, coefficient of friction and wear ratings. At the same time, the technical data of the fluctuation beyond the rated performance listed above are listed. Rectification performance values to illustrate some of the black brush rectifier performance. If you can assess the performance of some of the brush to brush to determine the general law of changes in performance, then the importance of the information listed can be greatly enhanced. In solving this task, it is very important to choose the correct index to study the regularity of performance change.
