An Electrical Machine Design Technique Combining Magnetic Equivalent Circuit and Finite Element Methods

자기회로법과 유한요소법을 결합한 전기기기 설계

In this paper, the space mapping algorithm is proposed for the design of electric machines. By the algorithm, we can combine the magnetic equivalent circuit and the finite element models mathematically and got the final design parameters with a few iterations while preserving the accuracy offered by the finite element model. The finite element model is generated by parametric techniques. For the validity of this algorithm, a simple permanent magnet device with fringing and leakage flux is dealt as a numerical example.
