- Abstract
- When we design the PM machines, accurate calculation of inductance parameters are very important. Inductance parameters have nonlinear characteristics along the magnet size, because of iron core is saturated by magnet flux and armature reaction flux. In this paper, we calculate inductance parameters by magnetic equivalent circuit method and finite element method. Moreover, we compensate the equation which is related to d-axis inductance of magnetic circuit method by using saturation coefficients. Finally, these coefficients are interpolated by the suggest method.
