Condemning a Motor Using MCA™
Experience has shown that 20 to 40 percent of motor systems tested may have some sort of alarm condition. Just because a motor has exceeded the alarm limits in MCA Basic™ or MCA PRO™, it does not necessarily mean the motor will fail or should be stopped immediately. For over 30 years, the dedicated staff at ALL-TEST Pro have gathered data and resources to determine when a motor will most likely fail on the most common 3-phase squirrel cage motors.

Reading and Understanding Key Accelerometer Specifications
There are many ways to evaluate an IEPE (Integrated Electronic PiezoElectric) sensor, or accelerometer, either on its own merits or in comparison to similar competitive models found on the market. The most obvious is a paper comparison, using the spec sheet as a guide. Other options include acquiring the contending sensors and putting them to the test or obtaining word-of-mouth inputs, each of which will likely result in a different conclusion. The most common starting point, however, is a spec sheet appraisal.

Reducing Costs with ESA and MCA™ Technology
More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..
