Analysis of Distributed Airgap Magnetic Density for Induction Motor using Magnetic Equivalent Circuit

자기등가회로법에 의한 유도전동기의 공극자속밀도 분포해석

In general, the results of finite element method(FEM) on the analysis of the electrical machines has known as high accuracy but required very long time to calculate the field distribution. Magnetic equivalent circuit(MEC) method can be computing times less than the finite element method and also it provides steady state and transient state simulation. In this paper, describes matrix representation of the winding magneto motive force(MMF) and carry out the distributed the airgap magnetic density takes into account the influence on the stator slots.
