John, as of now energy auditing & testing bureau are offering various star rating to the devices based on certain parameters. In general it depends up on energy consumption and efficiency. But how the new system is going to define these parameters?

Thanks for your comment.

DOE is working with the fan group on how they will test. They only want to cover the fan and not a complete system. The proposal is to use a motor with an efficiency as high or higher then the original that was certified with the fan as static pressure changes and larger motors are needed.

For pumps, the group is looking at a similar EU regulation and test methods set up by the Europump organization which takes all components into consideration making it closer to a plug to water efficiency.

These proposals will be studied by DOE and their technical partners at Lawrence Berkely Labs. There will be chance for public comment during the rulemaking process.

While improving efficiency is a valid target, the creation of rules will undoubtedly lead to problems because firm rules seldom are able to cover all conditions. So instead, how about just creating a uniform standard for measuring and reporting efficiency and not making so many rules. In some instances efficiency is far from the most important consideration, seldom used emergency equipment and systems being one example.

Excellent information John.  I just hope the DOE continues to include industry when determining development to standards or altering existing standards.  I would hope also all efforts include looking at existing standards and methodology for developing standards relative to global sales and marketing.  If we can develop products that can be used in Western Europe and possibly the Far East "up front" we will be money ahead in the long run.  I retired from a company that made considerable efforts to adapt products designed for US markets to European markets.  In the long run, the efforts provide products that simply did not compete.

William K., I'm with you.  Require motor companies to publish efficiencies and clearly label them on the motor nameplate; let the market drive the need.

In another discussion it was pointed out that some OEMs would choose the cheaper less efficient motors to use in thier products to gain a price advantage. So probably any rules would have to include having the motor efficiency information included in the product advertising materials. Sort of an enforcing of "truth in advertising", which I am sure would pain some folks a lot.

End users are becoming motor conscious, specifying premium efficiency motors to decrease their electric bills.

Enough end users asking for better motors will force OEMs to step up.

Thanks for the comments guys.

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.

J.M. You are certainly correct on the costs. But like many other times the challenge is to make the purchasing people understand that reality. That task can require  a bit of effort.

Thanks John for your clarification.

The standards electrical machines and components are required to meet in the food processing industry are far more stringent than those in traditional plant construction.

Just because it has a computer inside and is connected to the Web, does not mean it is smart.
