| Abstract |
In this paper, a multi-purpose geometrical optimal design of a 1000 kW high-voltage induction motor was proposed for improving the output of the motor and reducing the temperature using a high-grade iron core and magnetic wedge. The Global Response Surface Method (GRSM) was used to satisfy the multi-objective optimization in complex design problems related to power and temperature. GRSM performs parallel analysis for accurate and efficient optimization searches, including local and global search capabilities.
In addition, Hyperstudy a commercial optimization program, and an electromagnetic FEM solver were used to analyze the motor. As a result of optimum motor design, the output increased by 8% and the temperature decreased by about 10 % compared to the base model. The reliability of the proposed method was verified through experiments. |
