The importance of a good-quality motor repair

International Repair Standard

One way to ensure a quality repair is to ask your provider if they follow the international repair standard (IEC 60034- 23). The standard establishes the benchmarks for repairing rotating equipment, maintaining efficiency levels, high standards of quality control and improving efficiency in associated pieces of equipment.

The standard covers many other aspects of the repair process. It sets out requirements for the maximum temperatures used in an oven to burn off old windings to prevent damage to the steel laminations. It covers which insulation grades should be used, the approach to rebuilding bearing seats, the selection of replacement bearings and grease, and a range of other factors.

IEC60034-23 also sets out what tests should be carried out on a motor before and after it is repaired and how the test equipment should be maintained and calibrated.

In line with the repair standard, a good motor repairer should have a repair specification they can give customers, showing what will be done. And when the motor comes back from repair, there should be an accurate record of what has been done, including certificates covering aspects such as balancing, vibration measurement, tolerances, and surge test results.

So, to ensure you get levels of reliability and efficiency from your next motor repair, ask your repair provider if they work to the international repair, overhaul and reclamation of rotating equipment standard, IEC 60034-23.
