Recommended Slipring Material ?
(OP)
What is the ideal slipring material for a 1.6 MW, 1500 RPM motor with a rotor current of about 900 Amps ? The motor is for a paper mill where there is lot of moisture and hydrogen sulphide (H2S) is used for bleaching.
1. Phosphor Bronze (what is recommended alloy composition)
2. Brass (80 Cu 20 Zn)
3. Steel
4. Copper
Also, what is recommended grade of carbon brush for such a slipring working in the said atmosphere ?

RE: Recommended Slipring Material ?
CuNi = 94%Cu, 4%Ni, 2%Zn Harder than above to cast but superior to wear even in contaminated areas.
Monel Metal 29%Cu, 68%Ni, 3% combination of C Fe Mn. Used in corrosive atmosphers e.g. sea water, ammonia.
Also gummetal ASTM B143-1A opr 1B
And there are others as well.

Thx Doug.
From H2S point of view, which is better material? I have seen copper turning black in hydrogen sulphine environment.
