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.

Motor Storage

One thing that is typically overlooked is how spare motors are stored. Over time, moisture, dirt, dust, and even general vibration from other sources can have a negative impact on the electrical and mechanical condition on the stored motors.

Machine Monitoring and How ESA Technology Can Upgrade Your Plant’s Reliability

In many cases, the quality of the power supplied to the motor system may be the cause of a breakdown or failure. The result of poor “power quality” is usually long term and often overlooked as the source or contributor to the problem. Knowing the quality of the incoming power, along with the mechanical and electrical condition of motor and the mechanical condition of the drive are important at all facilities to maintain uptime & save money...
