How to ensure you get a good quality motor repair

04 September 2023

With growing financial and supply chain pressures, repairing a motor is an increasingly viable alternative to replacement. But for a repaired motor to perform as well as – or even better than – when it was new, it is essential that you get a quality repair. Karl Metcalfe, Technical Support at the Association of Electrical and Mechanical Trades (AEMT), explains what to look for when commissioning a repair.

There are several ways that a poor-quality motor repair can impact a business. First, there could be issues with the energy efficiency of a badly repaired motor, leading to unnecessary increases in costs. However, if repaired well, a motor should be at least as efficient as when it was new. This was demonstrated by a study carried out by the AEMT and the Electrical Apparatus Service Association (EASA), which confirmed that higher efficiency IE3 units are unaffected by a repair that uses good practice procedures.

A motor that has not been well repaired can be prone to early failure. Winding faults can lead to premature insulation breakdown, while poorly fitted bearings can fail sooner than expected. If these faults occur, the cost of unintended downtime could be massive.

There are ways to identify a good quality repair, and this can start before the repairer even sets eyes on the motor.
