【Abstract】 In this paper, based on experiment verification, more precise formulae, air gap magnetic conductance and leakage magnetic conductance, can be obtained using the results of magnetic field. Based on these two formulae, not only can the established equivalent magnetic circuit maintain the advantage of the original circuit method, but also improve the calculating precision.更多还原
