Doosan Heavy Industries and the Korean Electrotechnology Research Institute (KERI) have demonstrated a compact, high-efficiency superconducting motor.
The motor produced by Doosan and KERI utilizes approximately 5,000m of American Superconductor Corp’s high temperature superconducting wire and is capable of generating 1,300 horsepower at 3,600 rpm.
The system is significantly smaller, lighter, quieter and more efficient than the traditional motors sold today of the same power rating, which are made with copper coils, the company says, estimating that the annual worldwide market for industrial motors with ratings of 1,000 horsepower or higher is over $1 billion.
