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.

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
