Not all electric motor rewind and repair shops offer the same standard of repair. At FML we are passionate about quality and best practice. We ensure all our repairs are ‘as good as if not better than new’ we give you information on why the motor has failed and help you prevent the failure happening again.
Three reasons to choose SKF certified repair shop Fletcher Moorland.
- The right know-how. Since 40% to 70% of motor failures are related to bearings, it's no surprise that high-quality bearings are key for reliable motors. But the right bearings alone won't deliver the results you need. How parts are installed, lubricated, handled, stored, aligned, transported, and maintained is equally important. At Fletcher Moorland, technicians complete extensive training in electric motor analysis, bearing installation, lubrication systems, and condition monitoring technologies-giving them the skills they need to perform optimal diagnoses and repairs.
- The right resources. Fletcher Moorland have access to SKF’s unparalleled collection of parts, tools, and technical support. We are kept up to date with the latest technologies and best practices. And we’re empowered to perform root-cause failure analyses and troubleshooting. In short, we have the resources they need to do your repair right.
- The right approach. Becoming SKF certified isn't a one-time process. Fletcher Moorland must complete regular audits to ensure compliance with our rigorous standards. They must also meet SKF’s requirements for continuous improvement and competence development. Because when we improve, so do your bottom-line benefits-including enhanced performance and reduced cost of ownership.
This is what you can expect from using FML for your motor repairs
• Less electric motor service variability, as well as consistent specs and standards at all locations
• Consistent and high-quality repairs that will provide longer, more reliable motor service life
• Support in implementing best-in-class practices across the board
• Repairs that use only SKF bearings so that high-quality components become standard-and second-rate components are avoided
• Better technology from the motor service supplier and access to new technologies
• Highly skilled motor service suppliers capable of root-cause failure analysis and troubleshooting
• SKF oversight and management of program certification
Brief repair specification
This is a brief outline specification for a typical motor repair.
- Each motor is run and a vibration conformance check is carried out.
- The motor is stripped and a root cause failure analysis is performed. This includes a strip-down and analysis of the bearings.
- The motor windings are tested using Baker surge test equipment.
- The bearing housings and journals are ‘8 point’ measured using precision digital micrometers capable of measuring to 3 decimal places to check for correct SKF fit tolerances.
- The rotor is balanced to an enhanced G1.0 balance specification. (Better than a new motor)
- All stators are stripped using a controlled pyrolysis (burn off) oven set to 370 °C to ensure the motor efficiency is not affected.
- Lexseco Core loss testing is performed before and after stripping to prove motor efficiency is not affected.
- Stator rewinds are carried out to full class ‘H’ specification (better than a new motor)
- Genuine SKF bearings are fitted to SKF procedures using a degaussing and temperature controlled bearing heater.
- The motor feet are checked for flatness.
- The motor is run tested and vibration conformance is recorded and analysed against strict SKF specifications.
- A compressive service report is compiled and shipped with the motor.
- All rewound motors are covered by a 2 year guarantee (Better than a new motor)
