Development of FE-based computer-assisted design system for induction machines

This paper describes the software environment for computer assisted design of three-phase squirrel cage induction machines. The finite element method is used as a computational technique to account for detailed geometrical properties, skew, material nonlinearity and deep-bar effect. The system enables determination of all electromagnetic quantities that are usually of interest of the designers of electrical machines. Besides of that it enables the design optimization. The design of experiment is used as a principal method. Sample results of calculations compared with measurements and sample design optimization are presented.
