The new motor line, the Cedar(TM) Series, includes motors ranging in power from 250 to over 2,000 horsepower (HP). The Cedar(TM) Series motors are available through the company's DRS Electric Power Technologies unit in Hudson, Massachusetts, and Canopy Technologies, LLC, a Houston, Texas-based company formed by DRS and Elliott Company, Inc. Elliott Company, headquartered in Jeannette, Pennsylvania, is a wholly-owned subsidiary of Ebara Corporation (TSE: Code no. 6361), one of the world's largest manufacturers of industrial pumps and related equipment.
The Cedar(TM) Series motors are competitively priced and well suited for pumps, fans, well drilling systems, material feed systems, mining equipment, conveyors, hoists and offshore system applications.
The model CR32-50 radial field brushless permanent magnet motor, the first in the Cedar(TM) Series, is rated for 500 HP at 3,000 revolutions per minute (rpm), with a maximum speed of 3,600 rpm. The CR32-50 is capable of producing a continuous torque of 1,300 lb.-ft. at stall speed (0 rpm). When combined with DRS's High-Performance Drive (HD) 500, the motor can be operated at variable speeds from stall to rated speed and at a full range of torque up to its maximum continuous torque rating.
A key advantage of brushless permanent magnet motors is the significant reduction in weight and size over equivalently rated conventional electric motors. The CR32-50 weighs approximately 500 lbs., has a width of 18.9 inches and a length of 17.3 inches, and requires approximately 5,000 cubic inches of space. A conventional motor with an equivalent rating typically would weigh over 2,500 lbs. and require over 15,000 cubic inches of space.
The Cedar(TM) Series motors build on the high-performance machine designs and electromagnetic technologies developed over the past twenty years by DRS Electric Power Technologies. DRS Electric Power Technologies' recent developments include the world's largest, commercially available off-the-shelf permanent magnet motor, the PA 57 with 1,000 HP, and the design of the world's largest, single-application permanent magnet motor and electronic drive unit that will provide approximately 50,000 HP of ship propulsion power targeted for the U.S. Navy's DD(X) next-generation multi-mission destroyer.
