Commonsense Motor Management under EISA Efficiency Standards
It’s no secret that the Energy Independence and Security Act of 2007 (EISA) is in effect now. The law sets efficiency standards for three-phase AC induction motors from 1 to 200 hp. The new efficiency standards require that motors manufactured after Dec. 19, 2010, conform to the NEMA Premium efficiency standards. Old motors can still be rebuilt and sold, as can new old stock of pre-EISA motors.
Energy prices are climbing faster than most other costs, so we should be able to find a financial opportunity buried in EISA. But face it, guys, when you’re operating at the three-way intersection of the law, electrical engineering, and accounting, it might be a little hard to find exactly the information we need. Manufacturers need to find their way to a solid motor strategy.
