Letrik Kama is your single source for reliability field services. Whether it is simply motor repair or complete motor management, pump, and gear box repair we have the experienced personnel and technology to maintain, test and analyze your assets.
In the event off-site evaluation is required, we will pickup, diagnose, repair and return your equipment. To minimize downtime, we may be able to keep your operation up in the meantime with a unit from our inventory of exchange motors.
AC and DC Motor Rewind
LETRIK KAMA has mastered the art of electric motor repair. All repairs begin with through documentation, testing, and inspection by hipot and surge test also megger insulation test.
Rewinding starts with the original windings being carefully removed by our safe stripping method. This method maintains the integrity of core iron and mechanical characteristics without damage.
Windings are tied down at both ends and electrically tested prior to varnishing. Stators and armatures are varnish by using conventional dip and bake methods.
Recognizing no two repairs are alike, we also have the flexibility to meet a wide variety of customer repair requirements. We carry a full stock of replacement parts, materials, and a complete wire inventory to handle special repairs. Our many capabilities include dynamic balancing, vibration analysis, generator winding, documentation, assembly, and testing.
Large Motor (High Voltage) and Generator (Low voltage) Winding
All repairs begin with thorough documentation, testing, and inspection of the motor when it arrives at our facility to determine its integrity, root cause of failure, and to benchmark existing conditions.
Windings are tied down at both ends and electrically tested prior to varnishing. Stators and armatures are varnish by using conventional dip and bake methods.
Whether on-site or in-house, our trained technicians inspect, analyze and expertly dynamic balance your rotating machinery using computerized instruments. For smaller motors or pumps, our technicians can use portable balancing units at your facility. However, for larger machinery, our in-house equipment can accommodate up to 14,000 lbs. Both on-site and in-house precision balancing services are available on request.

Electrical testing, polarization index, surge comparison and other tests are performed. Maintenance includes inspection, cleaning, lubrication, minor repair work, and more. We can inform you of any recommendations or additional service required.
We offer the following types of test:
1. Surge, HiPot and PI Test
We offer the following types of test:
1. Surge, HiPot and PI Test
Surge Test: Enables us to test the motor from phase-to-phase,phase- to-ground and turn-to-turn.
DC Hi-Potential Test: Enables us to examine ground wall insulation that may be damaged due to breakdown or high leakage current.
PI Test: Enables us to examine the gradual deterioration of the insulation and the need for replacement.

PI Test: Enables us to examine the gradual deterioration of the insulation and the need for replacement.
2. Vibration analysis
This allow identification of problems due to imbalance, misalignment, resonance, bearing, motor component, ect.
Our team will checks to ensure bearings are not defected or worn and mechanical fits are correctly in place.

3. Balancing
This test balances the vibration of a rotating piece of equipment. Balancer will analyze wheter there is any imbalance in the shaft that can be addressed by the addition or subtraction of weight, ensuring that the shaft runs smoothly and efficienly without damaging your motor.
4. Rotor Bar Testing
A broken rotor bar will negatively impact balance and performance of the motor. This procedure ensures that the bars in your rotor are not broken or cracked.
Proper shaft alignment can prolong the life and improve the efficiency of motors and other integral equipment. Our experienced staff will accurately analyze and align your machinery to optimum performance. Our technicians can also perform corrective work on bases, frames, mounts and other structures.

We also provide services to repair housings, bearing journals and shafts to offers you the most comprehensive service to get your production up and running.
.......
Thermal spraying also commonly known as metal spraying is a surface engineering/coating process that repairs surfaces on parts by first machining down the worn surface and building it back up by depositing cladding material in thin layers to restore the worn surface. This process can provide corrosion protection to ferrous metals, improve the wear resistance or thermal conductivity.

Our skilled technicians disassemble, inspect and record precision measurements at the onset of every repair project. Our welders can repair most any metal, including exotics. Technicians perform dynamic balancing during reassembly, and prior to shipment to ensure that your pump has been repaired to our exacting standards.

Prior to repairing a gearbox, we performs failure analysis to determine the root cause of the failure. Replacements parts are ordered directly or manufactured in our complete machine shop. After performing the repair, we carefully document all repairs to be sure that your gearbox repair has met our exacting standards.
We offer the following types of gearbox repair:
1. Offset
2. Bevel
3. Planetary
4. Helical
5. Sequential
