Tips to Select an Electric Motor Repair Shop

While choosing an electric motor repair shop, it’s important to select one that is reliable. Reliable electric motor repair shops reject sub-standard materials and offer electrical conformance testing. In addition, a good electrical motor repair shop have an on-staff technical expert who can provide both post-repair support and root-cause analysis. Most end-users assume that a repair shop will know enough about electric motors to perform repairs correctly, but this isn’t always the case.

Reliable electric motor repair shop will reject sub-standard materials

Reliable electric motor repair shops will work with their suppliers to use high-quality materials. They will also reject sub-standard materials and parts. Sadly, the electric motor repair industry is one that has very tight margins. It’s easy to use sub-standard materials and parts to get the job done, but this approach can leave the repair quality at risk.

Performing a root cause analysis will help determine why a motor fails, and a business case can be developed to resolve the problem. For example, replacing oversized and under-loaded motors can improve the efficiency of the equipment and reduce energy expenditure. In addition, replacing damaged motor windings may help improve motor efficiency and reduce energy spend.

Quality repair requires individual attention to the motor. In contrast to mass-production motor manufacturing, a quality repair shop can work to tighter tolerances. It can also perform modifications to better match the application.

Reliable electric motor repair shop will accept electrical conformance testing

A reliable electric motor repair shop will conduct electrical conformance testing to ensure the proper functioning of your motor. This testing requires a variety of advanced equipment, including a specialized winding analyzer and a core-loss tester. This type of testing can detect degradation of turn-to-turn insulation. Electrical conformance testing also requires a high level of documentation. Quality repair shops do not cut corners in this area because it may result in a faulty motor.

Electrical conformance testing must be done by an experienced engineer in a controlled environment. Most motor service centers have dynamometers that can measure motor efficiency. These equipments are vital to the motor repair process. However, motor repair procedures often make it difficult to perform efficient measurements of motor efficiency. It’s possible for a motor to lose up to two percent of its efficiency after repair. The DOE’s Motor Master+ program defaults to a loss of efficiency of 0.5 or 1.0 percent after repair.

Reliable electric motor repair shop will ask for referrals

There are several advantages to selecting a reliable electric motor repair shop. These shops offer a range of services and will be happy to offer referrals. Reputable shops meet rigorous quality standards and are certified by a renowned engineering firm. They will also offer a warranty on their repairs, which is invaluable for companies that rely on electric motors.

If possible, choose a company that has been in business for many years. This way, you can ask them questions and get their honest opinions. While some repairs can be expensive or even require a replacement, a reputable technician will be upfront with you and advise you accordingly. You should always ask for referrals if you need to have a certain type of electric motor repaired. This way, you can be sure that you are receiving the best care possible.

In addition to asking for referrals, you should visit the repair shop in question in order to assess the quality of their work. A quality repair can take several days. It can also be more expensive than anticipated, especially if hidden problems are present.
