AC Motor Remanufacturing
Matlock Electric uses quality materials and replacement parts to insure a quality repair. Mechanical parts are closely examined and measured in our machine shop. In-house dynamic balancing of all rotating parts is also provided to assure precision vibration results. Matlock is a certified SKF facility, using only the latest technology to guarantee the proper installation of the highest quality bearings.

Our rewinding process includes only high temperature, Thermaleze Q inverter grade copper magnet wire, Class H Nomex in-slot and phase insulation with polyester or epoxy resins available through our exclusive VPI* system. Winding data is verified with engineering programs based on both Manufacturer's and EASA data. All magnetic cores are tested and repaired to insure maximum efficiency. Vacuum Pressure Impregnation (VPI*) with epoxy resin completes the rewinding process.

Throughout the remanufacturing process, each operation is completed by well-documented testing procedures, including surge testing. This aides Matlock in upholding its strict Quality Control Remanufacturing Policies.

DC Motor Remanufacturing
With literally decades of experience, DC equipment repair has become a specialty at Matlock Electric. We service a wide variety of industrial customers and also provide services to other motor repair centers.

DC motors need maintenance often because they are subject to various speeds, types of loads, and contaminants in addition to the normal brush and commutator wear. Close examination and special test procedures such as surge, high frequency, hipot, dynamometer and megger testing are a must in this business. Precision tolerances and proper brush grades are required to maintain good commutation and brush life. Small problems left unattended often turn into unexpected production breakdowns.

All coils are wound on computerized machines for uniformity and accuracy utilizing Class H wire, phase insulation, and other insulating materials. All units are dynamometer load testing prior to shipment. This insures that the units can operate in the harsh conditions of a plant setting.

Our DC department utilizes equipment such as our JEMS Armature Cleaning System, CAM Automatic Laser Commutator Undercutter, Baker Advanced Winding Analyzer, A&W Dynamometer Load Tester and Miller Syncrowave Welder that enables us to deliver the best quality and repair your equipment.

Machine Shop
Matlock's machine shop is equipped with Lathes, Milling Machines, Boring Mills and other equipment specially suited for the electrical equipment industry. Our fully equipped machine shop allows us to repair flange/housing end shields, shafts, and commutators. Our computer controlled Harrison Lathe allows us to complete high-speed accurate components in minimum time. This allows Matlock to have incredible flexibility within the repair process and has helped us deliver RUSH Repairs on time.

Testing
Matlock uses diagnostic testing equipment throughout the remanufacturing process to insure quality workmanship. All testing data is documented and logged into our database for future reference and baseline trending.

One of the most critical capabilities of an electric motor repair shop is the ability to test run remanufactured motors at full rated nameplate voltage. Test running electric motors at full rated voltage is important for several reasons. Accurate vibration levels can be measured only at full voltage and mechanical problems do not always show up at less than full voltage. The most reliable electrical test of a winding is energizing the winding for full voltage tests.

Customers of Matlock Electric receive remanufactured motors that have been fully tested and run at nameplate voltage. This insures reliable operation when the motor is installed in the plant.
