European OEMs in the Dark About New Motor Efficiency Laws

Posted January 19, 2011 8:30 AM by Sharkles

Up to a third of Europe's OEMs are in danger of being left behind when looming regulation takes effect. According to The Manufacturer, nearly a third of OEMs are unaware that legislation mandating minimum motor efficiency levels will go into effect all throughout the EU starting in June 2011.

The new rules set ratings for three-phase AC motors in the most common industrial power range. Not adhering to these guidelines could result in serious repercussions for the manufacturers' sales and market share.

When the legislation takes effect in June, all new, general-purpose AC motors will be required to meet a minimum efficiency of IE2. This standard is equivalent to the previous CEMEP 'EFF1' standard.

Baldor, a manufacturer of motion controllers and servo drives, says that most OEMs are currently using lower efficiency EFF3 or EFF2-grade AC motors. Transitioning to higher-efficiency equipment designs can require changes to the physical and mechanical interfaces, rotational speeds, and to thermal issues and starting behavior. Many of these issues are time-consuming and can cause major downtime for unprepared OEMs.

Are you ready for the impending motor efficiency regulations?

I used to work in a sawmill. A new saw box came in with 4- 250 hp high efficiency motors on it. Occasionally we would jam a cant in the saws and stall the motors. What we found was that, due to high stall currents, we would pull the winding in the motor. Needless to say, the motors didn't last long. Our local motor winding shop could not rewind the motors due to the fine windings. We had to find old heavy motors to replace the new motors. These would last a lot longer, years vs months, and were rewindable. The new motors went for scrap.

It wont be the first time government mandated efficiency rules made everything cost more and become less reliable for the end user.
