"In the past, OEMs would concentrate on first cost, specifying lower efficiency less expensive motors and components. Users have demanded a more robust machine that increases productivity and lower life cycle cost. The life cost of a motor is only 2%; over 97% is energy cost."

John, how and on what parameters these figures have arrived. Actually for a motor investment si more and we have to account wear & tear, interest part of the investments etc.

You bring up two important items. The first is changing the paradigms for purchasing folks. We historically have rewarded them for saving money on purchases, but that does not play well with today's idea to increase productivity and reduce downtime and energy consumption. Its like the old oil filter commercial, you can pay a little more now or a lot more later. Purchasing folks need to be on the team to know that cutting corners has a big effect on the bottom line.

If I understood better how I might be able to post a pie chart here, the one would show motor purchase at about 2%, electricity at around 97% and maintenance of the motor at a little less than 1% over its life cycle. We created this graphic about 25 years ago. A recent study by NEMA and MIT showed the lifetime carbon footprint from a motor as about 99% from electricity usage.

John, thanks for the details, but still not convinced how you figure out these values.

To figure out the life cost of a motor, simple calculations use hours operated, motor energy consumption to see the cost of energy over a 20 year life for the motor. We know the motor purchase price and another guide gives us the average repair cost for replacing motor bearings and cleanup in the middle of the motor's life. These are the 3 slices of the pie.

John, thanks now I got it. it's a best assumption by considering the various factors and neglecting the fact that Motor won't stop work in between.
