Motor Circuit Analysis™ (MCA™) is a test method that determines the true state of health of 3 phase & single-phase electrical motors. MCA™ checks the motors coils, rotor, connections, and more. MCA™ can verify ac motor winding resistance as well as dc motor resistance and determine state of health.

Bearings operating in or near heat-generating equipment are subject to temperatures that cause ordinary greases to melt and run, leaving critical bearing surfaces unprotected. A reliable long-lasting grease that can withstand extreme heat is needed to extend re-greasing intervals and prevent premature bearing failures.

Technology in predictive maintenance is growing fast, and so is Condition Monitoring which is one of the its most important activities. In particular, the wireless sensors in Condition Monitoring came to change completely the way we used to see machinery reliability.
What is Condition Monitoring? What do we need to learn about modern technologies applied in it? Well, I am a Vibration Analysis technology developer and I invite you to take some time to read this few tips I have written for you.

Online monitoring is the process of utilizing permanently mounted sensors to regularly check the condition of a machine. Online monitoring should consist of more than just vibration sensors. Given there are many different failure modes it is best to utilize a variety of sensor types to monitor the necessary variable to ensure early warning of failure.

Reduce Energy Costs and Increase Process Stability with Ultrasonic Testing Equipment. Regular inspections of production equipment are essential in preventive maintenance. Early detection of damage or signs of wear leads to increased plant availability and also saves enormous costs. Is the steam trap working correctly or is it defective? Digital ultrasonic testing technology provides the answer. Energy losses are reduced and process stability is increased.

Pumps are critical pieces of equipment in a large variety of industrial settings. Although they are routinely monitored as part of a facility’s CBM program, the data captured in this way isn’t always enough to identify the signs of early-stage pump cavitation. Vibration data can provide valuable insight into the pump’s condition, and with the right monitoring setup can help you identify developing cavitation before serious damage or failure occurs.

In the Part 2 the practical example will be analyzed.
Let’s look the background and calculate the most common frequencies produced by motor that potentially will be required for further analysis.

A small, but critical, motor in a pulp and paper mill exhibits a changing and rising resistive imbalance indicating a power circuit anomaly. If the motor fails, the loss of production costs could be up to $20,000 per hour. Follow along as they test and investigate the problem.
