How to deal with the related problems of high-speed operation of electric collector slip ring products

Today, in the use of the collector ring, the problem comes to the high speed of the collector ring. Let's talk to you in detail:

First, the high rotation speed of the collector ring will cause two problems: the mechanical structure failure and the heating of the transmission contact point.

Second, generally due to the speed of the collector ring can reach 1000rpm when working, so, mechanical strength, wear resistance of steel material is the first choice of collector ring production, steel can be processed into complex structure, it is an easy to get and inexpensive material, so, widely used in including low circumference speed hydroelectric generator, synchronous motor. For collector rings, which mainly emphasize mechanical strength and wear resistance at high circular speeds, wrought steel is sometimes used.

Third, and in corrosion resistance, corrosion resistance requirements are high, can also use stainless steel material, but the sliding characteristics of stainless steel is not stable, and the brush combination is not suitable often make the brush beat, easy to cause the brush temperature rise is too high or abnormal wear, so the use must be more attention.
