Direct Drive Systems® permanent magnet (PM) machines open up new possibilities and unleash new approaches to products by original equipment manufacturers. Operating up to 23,000 RPM with power levels up to 16,000 HP, our PM line of motors range in size from 2MW to 12MW.
As a result of the high efficiency of our motors, the efficiency of an entire system is optimized. Our robust rotor construction maximizes rotor stiffness for higher bending mode frequencies. The low number of rotor poles reduces stator losses, and the latest technology in stator lamination materials minimizes stator iron losses.
Available in air-cooled or liquid-cooled versions, these machines offer the latest technology in high-strength, rare-earth materials for very high efficiency and very high power density (minimum size).
The unique nature of our Active PM Bias Homopolar Bearings also provides a number of inherent user benefits; see Magnetic Bearings.
