Conmutadores Riser insertados
Manufacturing Commutators With All Riser Types
Commutators with inserted risers can often be found in large to very large high-power DC Generators and Motors. At EMCC we can repair, re-insulate or re-engineer your Inserted Riser Commutator.
Inserted risers are generally comprised of flat copper strips with a high silver content and come in various shapes and lengths, depending on the application it’s used for. Commutator Riser styles and shapes can be customized to suit winding/coil leads. Each riser is fit into a notch or slot machined into each of the commutator segments. Each riser strip is then brazed or T.I.G welded into place.
V-ring, glass banded, and external shrink ring commutators can all have inserted risers. Commutators with inserted risers are often less desirable than commutators with solid risers because of their susceptibility to stresses and vibrations within the motor or generator. However, in many circumstances, because of the extremely long risers, they are the most viable and economical solution. In some cases, insulated spacers and or braided rope with a thermosetting resinous material may need to be installed. This will provide an increase in resistance to stress without increasing the mass of the riser.

Copper Segment Profile
Above is the profile of a typical copper Bar /Segment of a V-Bound / V-Ring Style Commutator with a double inserted type riser. Each inserted riser strip is either brazed with silver solder, Tig welded or riveted into place. Silver solder is the industry’s preferred method. This process happens before the assembly of the copper mica segments.
