@William K.

Thanks for verbalizing.  My reaction was very similar. 

My only edit would be changing: "there may be something else not mentioned in the discussion"  -- specifically change "may be" to a tone more suspicious of the unmentioned motivation.

In my observations, industries (industry sectors) do not normally invite more stringent regulations upon themselves for the sake of general & vague goodness.

Note:  I'm not of the paranoid ilk that waits for the consumer to get the short end of the stick after any industry move.  It's only that something just ain't normal in the picture this article paints.

Rules about efficiency? LET TRUTH PREVAIL!!
William K.   2/25/2014 10:14:52 AM

It seems that any buyer of motors, especially those that use a lot of power, would of course consider the efficiency of a motor as a major parameter in making the selection of which motor to select. This is true because in most cases the cost of power to run the motor over it's lifetime is far greater than the initial purchase price. The very rare exception is motors that are very seldom operated, where perhaps reliability and size are more important than efficiency. 

So while uniform test procedures would be a worthwhile rule to enforce, as well as truth in advertising and labeling, it wo8uld seem that the market would enforce the production of only the most efficient motors. Of course, there may be something else not mentioned in the discussion, such as a tendancy for some offsore sources to provide completely false information about their products, the most obvious is overstating wire sizes. Finding a spool of wire marked as number 12 and finding that it is actually much closer to what would be number 15 is not a nice surprise.

Latest Analysis
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
