DC ELECTRIC MOTOR REWINDING - REBUILDING
Carbon Brush Wear
Carbon brushes are designed to wear out over time. When carbon brushes wear, they can damage the armature, cause a loss of motor power, damage the commutator, and cause motor failure.
By checking your carbon brushes, we can determine if the brushes are installed correctly. Improper installation will spell operational problems and cause premature brush wear.
We look at the brushes for signs of wear or damage due to insufficient electrical charges, overloads, winding failures, surges, sparks, or problems with the commutator.
Regular repair and maintenance of your carbon brushes will extend the life of your DC motor and avoid the risk of unexpected breakdowns.
DC ELECTRIC MOTOR
DC motors often have to have field coils and armatures rewound and insulated. In some cases, repairs can be made but, sometimes, rewinding is necessary to achieve acceptable motor performance. If rewinding isn’t necessary, then the issue may be mechanical in nature or a build-up of carbon dust that can be addressed by steam cleaning and baking the field coils or armature.
When rewinding is necessary, careful measurements and documentation of the existing design are recorded. Making new field coil and armature coils are accomplished with precision by a skilled professional. The windings are then insulated, using varnish dip. The rewinding process includes careful testing and documentation at every stage.
We offer a comprehensive service for design and manufacture, installation, ongoing maintenance, rewinding, repair, and emergency breakdown service for all makes and models of DC motors
