Commutator Refurbishing, Rebuilding & Refilling
Electric Materials specializes in the rebuilding and refilling of commutators. Our experience is second to none when it comes to refurbishing commutators. Units are disassembled and rebuilt with new copper and mica segments using the same quality assurance processes applied to new commutators. Our extensive database of commutator information and history ensures that your unit is rebuilt to meet the operational demands of the final application.
When a commutator comes in for a repair, our engineers conduct failure analysis and then disassemble the unit inspecting each component. If the steel components are within tolerance, they will be cleaned and reused. All new hard drawn silver bearing copper bars, mica segments and hardware will be utilized to complete the unit. Depending on the application and customer requirements, the assembly will be processed to the applicable engineering instruction resulting in a finished product that is of the highest quality and will provide years of trouble-free service.
