The Right Efficiency for Your Application
To meet your cost of ownership and motor management needs, Siemens offers several levels of energy efficiency in many of its motors:
- High
- NEMA Premium
- NEMA Premium Plus
The World’s Most Energy Efficient Line of Motors
Lower your energy costs today with the world’s most energy efficient line of motors. New regulatory standards and rising energy costs create increasing pressure to maximize energy efficiency and reduce your carbon footprint. Siemens breakthrough copper-rotor motors have set new standards for efficiency. Adding copper to the stator windings, Siemens has developed motors that can withstand the heat. Two-thirds of an AC induction motor’s electrical loss occurs in the stator. The addition of the copper rotor reduces wasteful, resistive heating. Copper’s volumetric electrical conductivity is approximately 66% higher than aluminum.
