Analysing magnetic circuit is always very complex for the nonlinear feature of magnetic material.The existing methods for megnetic circuit analysis include analytic method
graphic method
and numerical method
etc.In this paper
a fractionation method model is established for megnetic circuit analysis
and a graphic method with the function of curve fitting tool in Excel is adopted to calculate the magnetic circuit.The sizes and magnetic fields of different parts of iron core are hence achieved
providing a basis for magnetic circuit design of permanent magnetic actuator.The experimental results show that the present method can simplify and accelerate the calculation
and visualize the solving process to facilitate further analyzing and optimizing of magnetic circuit.
