Using energy efficient motors of the DRE/DRP series allows for a significantly increased energy balance. SEW-EURODRIVE is the first company worldwide that has implemented die-cast copper technology in an industrial high-volume production. Result: The highly effective energy efficient DRE and DRP motors. The DRP motor surpasses the efficiency levels of the new international IEC 60034-T30 standard. It is labeled IE3 (Premium Efficiency). All this comes at a surprisingly economic price, which enables amortization within one or two years.
