New IE3 Compliant DRN Series from SEW-Eurodrive

As of June 1, 2016, all 2, 4, 6, and 8-pole asynchronous motors with a power rating from 1.0 HP to 500 HP must meet the efficiency requirements according to NEMA MG1 Table 12-12 and IEC energy efficiency class IE3. Motors that do not meet these Department of Energy (DOE) efficiency standards cannot be sold as new or replacement motors after June 1, 2016.

DRN-Motor-SEWTo comply with the new IHP ruling, SEW-EURODRIVE now offers the DRN motor. Not only does the new DRN motor meet the stringent IHP energy efficiency standards, it also fits existing gear units to provide easy upgrades and retrofits of gearmotors containing DRS (IE1) or DRE (IE2) motors. The new DRN motor has only marginal changes in weight and dimensions compared to the DRE motor. Plus, the DRN motor remains the same price as the DRE motor. The bottom line is greater efficiency at no extra cost.

After June 1, 2016, S1 duty DRE and DRS motors ≥ 1 HP will no longer be available as complete motors. However, non-S1 duty complete motors ≥ 1 HP will still be available, as well as replacement parts.
