The Frame 2 is the smallest, lightest, and most efficient high-power electric machine on the market today.  With a power range from 1MW to 2MW (up to 2,682 HP) and variable operating speeds up to 23,000rpm, the Frame 2 can be utilized for critical pipeline, marine, and offshore applications.  The PM machine has the built-in flexibility to turn down speed and power up to 50 percent of rated operating conditions, such as load and speed, while maintaining high operating efficiencies. 

From mechanical power input to electric power output, the machine’s overall performance, including all losses, has reached efficiency levels of over 97.5%.  Whether the machine is used as a motor or a generator, high efficiencies are consistently delivered without compromising reliability and availability.

The Frame 2 has undergone rigorous testing at both DDS and customer sites.  Some of the testing has included over speed operation, over current operation, and short circuit ride through.  The Frame 2 has outperformed and exceeded all expectations throughout these tests. 

The Frame 2 is offered with oil lubricated tilt pad bearings or active radial magnetic bearings.
