The Importance of Predictive Maintenance

As early as the 1960’s, many companies realized that by routinely monitoring the operating condition of rotating equipment it is possible to obtain an advanced warning of operational or other problems that would impact continued efficient operation. This early warning provides time to remove the machine from operation and affect minor repairs and adjustments before catastrophic failure occurs.

Prevent Motor Failure by Keeping Your Motors Clean

One of the easiest ways to prevent premature electric motor failure is to keep your motors clean and free of foreign contaminates. Many electric motors are fan cooled. When contaminates start to build up around the motor, air flow becomes restricted and reduces the ability for the fan to cool the motor which dramatically reduces the life the of winding’s insulation due to the increase in heat.
