Electric Motor Repair
Turbiville Electric believes in doing what we do as well as it can be done, using expert craftsmanship and the best materials. Our shop is optimized for repair of low voltage motors (up to 600volt) having stator dimensions of less than 3 x 3 x 4 feet. This range includes most modern 400hp motors. By keeping the shop at this size range, we have the capability to economically repair or rewind motors that larger shops turn away. The bulk of our work is standard motors, but we specialize in repair/rewind of special, irreplaceable, or antique motors. We have extensive experience and training with DC motors from tiny through 200hp.
Our philosophy is to concentrate on what we do best. We have developed relationships to partner with machine shops, fabricators, sandblasting/powder coating facilities, electrical contractors, and new equipment suppliers in order to give our customers what they need when they need it.
Our windings use Class H Nomex for slot cells, separator strips, phase insulation and top sticks. Phase insulation is taped down to prevent it from pulling up during binding.
Varnish is scraped from the core while still hot, rather than being removed with a drum sander. This prevents degradation of the core iron and loss of motor efficiency.
To prevent abrasion, coils may be wrapped with tape and then epoxy applied. Note the spacers in the slot to keep the wires compacted and to better protect the winding during any future bearing failure.
Wound rotors and armatures are within our capabilities.
Very small windings require special forms and techniques.
We contracted the complete rebuild of this blower including sandblasting, repairing and powder coating the housing and frame, rebuilding the motor, refurbishing the vibration sensor, and repairing the disconnect and motor starter.
An antique municipal siren where we contracted machine work to convert to ball bearing, then rewound the stator, and completely rebuilt.
We rebuilt this torque motor for a liquid slip compensator used for a mine hoist. The job was time critical and we were able to save time by repairing the 80-year old winding without doing a complete rewind.
We constructed a jig to wind Stamford UC series generator rotors, and purchased forms to duplicate the Stamford 2/3rd and 5/6th pitch stator windings. We also made a custom base and coupling so that we can spin the generators for testing purposes without them being attached to an engine.
