Consider your joints.

In inserted riser commutators, the connection between the riser and the copper bar is critical both mechanically and electrically.

Silver braze, while more expensive than the silphos traditionally used, solves the problem. In some environments, H2S (hydrogen sulfide) reacts with the phosphorus in standard silphos joints and causes increased resistance and decreased stability. In paper, metals, food processing, phosphate and gas plants, H2S is often the culprit, and the problem is exacerbated when the motor is subjected to higher performance standards than in the past.
