The commutator is the heart of a DC motor. While it doesn't take a large variety of materials to manufacture a comm the choices we make couldn't be more critical. With fewer DC motors in operation today, big DC required to perform better than ever. Did you know that silphos braze materials can actually cause issues with connectivity as the joint breaks down in certain applications? Instead, 38% silver braze will eliminate this risk and provide a stronger connection over time, both mechanically and electrically. The right material and design can prolong the life and performance of your commutators. https://iccinternational.com/building-process
