RELIANCE ELECTRIC ANNOUNCES DEMONSTRATION OF 5 HP SUPERCONDUCTING MOTOR

 CLEVELAND, Jan. 10 /PRNewswire/ -- Reliance Electric Company (NYSE: REE) has announced the successful completion and operation of a superconducting motor with an output power 2.5 times greater than previously developed Reliance prototypes. The motor is the first to be demonstrated with rotating high temperature superconducting coils.
 The alternating current (AC) motor was built with a rotating field winding made up of high temperature superconducting (HTS) wire. The HTS racetrack coils were supplied by the American Superconductor Corporation (NASDAQ: AMSC) with support from the U.S. Department of Commerce Advanced Technology Program. Four racetrack shaped coils with a total length of flexible HTS wire exceeding 670 meters were used in the demonstration motor.
 This new, more powerful motor, with an output power of 3730 watts, or 5 horsepower, and superconducting coils that rotate at 1800 rpm is a significant step beyond the earlier prototype that had stationary HTS coils and an output power of 1490 watts, or 2 hp.
 This 5 hp motor marks another milestone in Reliance Electric's long term program to develop commercial motors using HTS technology.
 The rotating field, synchronous motor with superconducting field coils is an engineering prototype of the same type of construction planned for larger synchronous motors (1,000 to 10,000 HP) that may be utilized for industrial and electric utility applications. Widespread use of HTS coils in large industrial motors has the potential for substantial energy savings, since superconductors can transmit electrical current with virtually no resistance and since their use will result in significant reductions in the size of large industrial motors.
 The Reliance Electric Company superconducting motor project is being sponsored by the Electric Power Research Institute.
 Reliance Electric Company, headquartered in Cleveland, designs, manufactures, sells and services a broad range of industrial and telecommunications equipment and has annual sales in excess of $1.5 billion. Reliance operates 48 manufacturing plants worldwide in 9 countries and employs approximately 14,000 people.
 The Electric Power Research Institute, Palo Alto, Calif., founded in 1972, manages technical research and development programs for the electric utilities to improve power production, distribution and use. Some 700 utilities are members of the Institute.
 American Superconductor, Westborough, Mass., is dedicated to the development of commercially viable applications of high temperature superconductor technology. The company creates and develops materials and manufacturing processes for making flexible high temperature ceramic superconducting wires, wire products and systems.
