Where cost and productivity are hugely important, preventing motor failure is a priority. However, when the worst does happen, you’ll need to rectify the issue quickly and efficiently to minimise the impact downtime can have on your business. Here, motor repair specialist Houghton International explains what should be considered to make an informed decision in the event of motor failure.

Repair or replace: the costs

When dealing with motor failure, it can be difficult to decide whether to rewind, repair or replace the motor. To make the best choice, a number of factors must be evaluated. When an issue arises, it’s very easy to jump to conclusions and start repair work. However, in some cases, repair work may not be the most cost-effective pathway.

Older motors could benefit from being replaced. The EPAct and EISA law are working in tandem to set new efficiency standards for electric motors, and we’ve seen significant improvements in efficiencies over the years. If your motor is older, you may not be seeing the cost-savings that these new motors offer, which can be substantial over the lifetime of the motor.

Repair work usually costs a lot less than full motor replacement. However, you should balance the short-term costs with long-term savings to make an informed decision that will truly benefit your business.

Downtime costs

Motor failure is usually a symptom of a larger problem. With a number of processes relying on the motor’s performance, downtime can have a significant impact on other areas of the plant, stopping productivity in its tracks. By doing so, you can then work out the best course of action. For example, if parts are needed or repair work will take an extended period of time, you could end up sacrificing a significant amount of revenue. In these instances, you may need to consider alternative measures, such as temporary fixes or the prospect of installing a new motor that is readily available.

Prevention should always be the priority. There are several different types of maintenance that can be carried out to ensure the longevity of your electrical motor.

Cleaning, lubrication and performance monitoring can prevent issues from arising, and falls under the category of preventative maintenance. Predictive maintenance includes monitoring the motor’s performance over time and establishing trends to work out when potential issues can arise, then putting measures in place to stop them.

Nobody wants of expects motor failure. While you’ll need to consider how best to react in such a scenario, the emphasis is clearly on preventing the situation arising at all, avoiding wasted time and lost revenue.
