Called Metric-E+, Baldor’s range of AC motors is dedicated to energy conservation, and employs unique technology to achieve outstanding energy efficiency levels of up to 96.3 %. The motor range spans 17 power ratings from 4 to 200 kW, with a choice of three speed options at each rating: 950, 1,450 and 2,850 min-1. In each case, users can choose from EFF1 efficiencies or Baldor’s proprietary EFF1+ premium option.
Maximum EFF1+ efficiencies at full load start at 90.1 % for a 4 kW motor and go up to 95.8 % at 90 kW (the end point for EFF1 labelling), continuing onwards to 96.3 % at 200 kW. Comparative EFF1 figures for the same motors are 88.5 % at 4 kW and 95.1 % at 90 kW.
The motor range features cast iron frames, for durability, and will run from 50 Hz, 380 to 420 V three-phase supplies. The motors are additionally rated for use at 60 Hz/460 V and comply with EPAct efficiency levels – making them suitable for use in the USA as well.
