It has not been Solved for years to calculate the basin electromagnet magnetic conductivity and its differential quotient. This paper will give the method and the results of the calculation. It is necessary to get help from a computer because of its feature. The calculation results and, the calculating flow diagram will be given in the paper.The most difficult thing to do is to deal with the shunt field pole which presents saturat state when the electromagnet is working, and the magnetic potentials on the surface of magnetic pole are not equal. The contribution of flux in the gap varies greatly with saturat extent. As the result of it, the magnetic conductivity is not only the function of the pole geometrical measurment, but also the function of the magnetic flux density. It brings more difficulties to the calculation work. The paper considers these factors thoughtfully and gives out the method and the results which are available for practice.Because it is the most important factor to change the charastcristics of the electromagnets, a simple analysis of the results will be given at the end of the paper.

盆形电磁铁工作气隙磁导及其微商的计算是国内多年来没有解决的问题。本文将给出它的计算方法。由于饱和磁分路的特点,计算工作需要计算机来完成,本文将给出计算框图和计算结果。 工作的难点集中在对饱和磁分路的处理。工作状态下盆边的深度饱和使得磁极表面不能看作是一个等磁位面。而且,气隙磁场分布随着盆边饱和程度的不同产生很大变化,使气隙磁导不仅仅是磁 几何尺寸的函数,而且是铁芯中磁感应强度B的函数。这给计算工作带来很大困难。文章周到的考虑了这些因素,提出了处理方法并做出了工程上可行的计算结果。 由于盆形磁极是影响该形式电磁铁静态吸力特性的主要因素,文章对计算结果做了简要的分析。
