DC Electric Motor Repair

Precision Electric separates itself from other DC electric motor repair facilities in many ways. Most DC electric motor repair facilities use the assembly line method which isn’t ideal because when many people work on the same DC electric motor, and the chance of human error drastically increases.

Precision Electric designates each DC electric motor repair to a specific mechanic, so the mechanic who disassembles the DC electric motor is the same mechanic who assembles and final tests the DC electric motor.

When Precision Electric facilitates a DC electric motor repair, an initial test procedure is performed to determine cause of failure and other problems which may exist, including armature and field frame rewinds.

Precision Electric performs rewinds on-site and is known to work around the clock on emergency jobs until DC electric motors are repaired and ready to be installed back into production.

DC electric motor repair introduces additional complexities into the repair process. The addition of a commutator with brushes, and rotating armature coils subjected to centrifugal force, which aren’t factors involved in typical AC electric motor repair.

The following procedures and tests are performed at Precision Electric to guarantee a quality DC electric motor repair.

Conductive carbon dust left by worn brushes is cleaned from the armature; then each commutator is checked for grounds and bar-to-bar shorts with detailed electrical testing.

Coils are manufactured in-house to assure proper fit. This eliminates constant bending and shaping during installation which can damage coil insulation. Proper banding is critical in DC repair. This ensures that the winding isheld in position during high-speed operation.

Field coils are checkedusing voltage drop testing. Bad fields and inter-poles are rewound in our shop on custom forms. TIG welding is available to eliminate soldered joints where design dictates.

All commutators are turned, undercut, and chamfered to provide the best possible surface for brush contact.For corrosive or other severe duty environments, commutator platinum plating is available to extend wear life (pickle-duty).Neutral setting adjustments are made during final machine testing to ensure proper operation.

All DC electric motor repair performed by Precision Electric is backed by a 12-month in service warranty. The Precision Electric in service warranty provides customers with a peace of mind knowing that their spare DC motors will be warrantied regardless of how long their spare equipment is on standby.
