That's right, Chuck. Every single new motor press release touts energy savings. It's hard to believe that just 10 years ago I did an article on energy efficiency in plants and it was a new topic.

I agree, Rob. Over the past ten years, I don't think I've talked to a motor manufacturer who hasn't made references to their improvements in efficiency.

You're right, naperlou. Industrial drives are the target here. They are one of the big culrpits in eating up so much of the world's electric energy. This chip isn't really targeted at pumps, fans and white goods, such as washing machines.

Good point Naperlou. The bright side is that the motors that are eating 40% of our electric energy are pretty much uniformly becoming more efficient.

Rob, I was suprised as well.  Of course, if you think of all the motors in a large factory, that makes for a large power footprint.  On the other hand, electric motors have become more efficient and power dense for a long time.  With control devices like this one from Analog Devices, they will become more precisely controlled and thus even more efficient.  Just one way engineering is making the planet a little cooler.

Resker's comment that motors eat up 40% of electrical energy is striking. With motors becoming more efficient, that could put a dent in electrical energy consumption.
