导电滑环的材质要求机械强度大，不但是电的良导体，还要具有耐腐蚀性，在与电刷滑动接触时，必须具备耐磨性和稳定的滑动接触特性。一般，钢质集电环的耐磨性好，机械强度大，因此大多用于因极性引起集电环磨损差较大的同步电机上。
The material of the conductive slip ring requires a large mechanical strength, not only a good conductor of electricity, but also a corrosion resistance. In contact with the brush sliding, it must have the wear resistance and stable sliding contact characteristics. Generally, the steel collector ring has good wear resistance and large mechanical strength, so it is mostly used for synchronous motor with large wear loss due to polarity.
滑环要求耐腐蚀性时，可使用不锈钢，但不锈钢的滑动特性不稳定，与电刷组合不合适往往使电刷产生跳动，容易造成电刷温升过高或异常磨损，所以使用时必须倍加注意。
When the slip ring requires corrosion resistance, stainless steel can be used, but the sliding characteristic of the stainless steel is unstable, and the brush combination is not suitable for the brush to produce beating. It is easy to cause the high temperature rise or abnormal wear of the brush, so it is necessary to pay more attention to the use of the brush.
径向集电环是一种非常常见的电器配件,正常运行时,三相绕组通过径向集电环引出的电阻短接.上绕有对称的三相绕组.启动时,在转子绕组中串入一个启动电阻,达到了减小启动电流的目的.径向集电环轻度振动时应及时处理,以免事态扩大.如果不及时处理,会致使压簧和电刷频繁损坏,径向集电环报废,电机轴径向磨细.
Radial collector ring is a very common electrical appliance. In normal operation, the three-phase winding is connected by a radial collector ring. There is a symmetrical three phase winding. When starting, a starting resistor is set in the rotor winding to reduce the starting current. If it is not processed in time, the pressure spring and the brush will be damaged frequently. The radial collector ring will be scrapped and the motor shaft will be grinded in radial direction.
