Hello Guys,
We are in process of setting up CM program for Motors on our Plant. One supplier offered CSI's Motor View package for Motor monitoring.

We want to listen others experiences who have used this tool. Anyone on the forum welcome to share their ideas....

Has any one used CSI's Motor View diagnostic package for Motor monitoring? Any cost saving achieved by use of this tool.

What defects of motor this tool is going to identify? Is it capable of identifying bearing related defects and lubrication problems?

Is this tool nice enough to be added in the CM Tool box for a Petrochemical Plant with > 1500 pieces of rotating equipment, most of them motor driven.

Any study about ROI for this tool?

Thanks in Advance...

Regards

Mohammad

Mohammad,

Here is a link to more info on CSI web site:
http://www.compsys.com/technology/motor.html
The MotorView software when used with current and flux sensors adds convience for motor current spectrum analysis. Both sensors can be used with a standard vibration analyzer and software. I use the CSI 2120 analyzer and MasterTrend software with CSI Flux Coil and Fluke current sensor. The MotorView software has nothing to do with bearings or lubrication. You can use vibration analysis and ultrasound measurements for these types of mechanical faults.

Thanks Walt for your reply.

We at our Plant already have Motor Manager to monitor all of our motors. This system has alarming and tripping at high and high-high levels of current unbalances. Also there are some other features in this system.

As you know the percentage of rotor bar defects for the motors is very low. Might be less than 5% of the total of all the other various types of defects.

Do you or any one else (reading this post)have a sketch or chart showing the various types of defects of motors and their percentages.(A survey report or a study)

Is it worth while to have such a CM package for motors which only detects rotor bar defects only.

Just for information, our plant is a Petroleum Downstream Plant with approx 1500 pieces of rotating equipment (mostly driven by motors)

Is there any other CM tool for Motor Condition Monitoring which can cover a lot more?

Thanks & best Regards

Artesis,a company in Turkey, makes a motor condition monitoring product that effectively monitors the motor and the motor driven equipment. From their marketing information

"MCM, Artesis award winning* and patented product, gives early warning of developing faults in pumps, compressors, fans and similar electric motor based machinery, thus eliminating the need for unplanned
repair and maintenance. Measuring only voltages and currents, MCM can detect conditions arising from faulty bearings, misalignment errors, load imbalance, isolation, and a variety of electrical and mechanical faults."

MCM won an award from Control Engineering in 2000 and it has been used by NASA and the US defense industry.

Steven,

Can you give a more detailed explanation on how this technology works? The brochure does not offer an explanation. Can you show sample data for examples of a machine with faulty bearings and other mechanical and electrical faults? How and who sets up the "Model" that is used to compare measured data with?

I have attached the MCM User's Manual. Most of the answers to your questions are in this document including how it works on page 25.
The model is part of the software and the beauty of this system is that once installed, the MCM "learns" about the motor and then looks for changes in performance. A good place for additional information is the manufacturer's website http://www.artesis.com/mcm.asp.

A new version is soon to be released which will have a wireless interface card.

If you have critical motors and want to learn more about MCM, give me a call.

Is this motor monitoring based on motor testing technologies? What are critical motors, are these HV motors?

I looked at Artesis' product and it actually does look like a nice little tool. My research found that they use a state-space model that assuems a model of the motor, but 'tweaks' it through the training steps.

Mohammad,

You should take a look at PdMA's line of motor testers.

You can get info on their offerings at www.pdma.com

Good Luck,

Do we need to monitor all motors? Any cut off point eg below 15kW, no need to monitor?
