2: Motor and Driven Equipment Selection

This is the 2nd in a 7 part Motor System Maintenance and Management Best Practices Benchmarking Study produced by Dr. Howard Penrose PhD of Success by Design and Terrence O'Hanlon, CMRP, Reliabilityweb.com.

There are several best practices to consider for motor and driven equipment selection. These best practices include repair versus replace decisions, purchasing decisions, motor sizing, speed changes and motor upgrades. Finally, you must consider motor failure as an opportunity, not a negative. Each of these opportunities provides the ability to make improvements to the motor system step by step.

Please use your best efforts to answer as accurately as possible.

If you are a service provider/contractor please answer for your largest client.

Add answers points for total score. We suggest you keep a running point total manually as there is a scoring key at the conclusion of this survey however - the survey is not autoscoring.

You may take this survey anonymously or you may provide your contact details if you would like an advanced copy of the study report and action recommendations.

Question Title

* 1. Which statement describes your company’s approach to electric motor repair versus replacement?

a. Motors are repaired versus replaced based upon the urgency of the reactive failure. (5pts)

b. It is usually left up to the maintenance person to decide on action. (10pts)

c. A repair versus replace decision is made before a motor is repaired using a tool such as MotorMaster Plus. (15pts)

d. A review of motors over a specific size is performed, as well as motors in critical machines. The review covers condition, the load and life-cycle cost analysis. Where it makes economical and reliability sense, operating motors are replaced prior to failure. When a motor fails, maintenance reviews the pre-made decisions. (20pts)

Question Title

* 2. When the company makes purchasing decisions about electric motors and driven equipment what does it consider? (Check all that apply) (3pts each)

a. Purchase price

b. Availability

c. Operating efficiency

d. Motor design

e. Estimated operating costs

f. Installation costs

g. Supplier support and backup

Question Title

* 3. What financial analysis method does your company use to select equipment? (Select one)

a. Life cycle costing based on cash flow (18pts)

b. Simple payback analysis (12pts)

c. Compare purchase price (6pts)

Question Title

* 4. How are motors sized? (Select one)

a. The operating speed and frame size (7pts)

b. Motors are sized to operate near 100% of their rated load considering starting requirements (14pts)

c. Motors are sized to operate newar their optimum efficiency point considering starting requirements (21pts)

Question Title

* 5. Does your company select premium efficient motors when possible?

a. Yes (10pts)

b. No (0pts)

Question Title

* 6. Does your company take into account speed changes when replacing motors with different models or brands, especially on centrifugal loads such as pumps, fans or compressors?

a. Yes (10pts)

b. No (0pts)

All of the points are added together and the total should be above 85 for world class, above 70 for an acceptable program that requires work and below 70, the program should be repaired.
