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.

Total Customer Support

When you’re looking for a motor, look for a highly trained specialist to help you match the right motor to your specific needs. Dietz sales engineers share the knowledge, training and experience to help you solve performance or installation challenges to ensure that you will receive the best value for your investment. Our customer sales staff takes pride in putting our customers first. Whether it’s an expedited shipment, tracking your order, or making sure your motor is properly installed, these professionals won’t be satisfied until you are.
