Determining Electric Motor Load and Efficiency - Energy

5 to 10 hp; peak efficiency is at 7.5 hp. A motor 's efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to extend over a broader range for larger motors, as shown in Figure 1. A motor is considered

PREMIUM EFFICIENCY MOTOR SELECTION - Department of …

Installation costs are the same for both motors. Given an efficiency of 95.5% and an electrical rate of $0.08 per kWh, a 250-hp energy efficient motor purchased for $13,500 and operated 8,000 hours per year at 75% of full-rated load will consume about $93,740 worth of elec- tricity each year.

Premium-efficiency motors: soon they'll be law. | EC&M

Jul 01, 1996 · In a little more than a year from now, most of your new motors must meet new efficiency levels mandated by federal legislation.On October 24 of next year and thereafter, most new motors manufactured must be of "energy-efficient" design. The Energy Policy Act of 1992 (EPACT) stipulates that most standard-efficiency motors will no longer be manufactured after that date.

Minimum efficiency standards for electric motors will soon

Jun 04, 2020 · The updated electric motor standards apply the standards currently in place to a wider scope of electric motors, generating significant estimated energy savings. DOE's analyses estimate lifetime savings for electric motors purchased over the 30-year period that begins in the year of compliance with new and amended standards (2016-45) to be 7.0 quadrillion British thermal units (Btu).
