摘　　要：极化磁系统具有一系列优点,应用广泛。极化磁系统永磁工作点的求解是极化磁系统研究的基本内容之一,它可为极化磁系统的进一步分析与计算提供条件;而图解法(现只能用于单永磁极化磁系统)具有物理概念清晰、简明直观谏钊肜斫饧畔低车谋局试怼Ｊ紫妊芯苛税ú疃胶颓攀皆谀诘牡ビ来偶畔低秤来殴ぷ鞯阃冀夥ǖ耐骋荒Ｐ臀侍?即在引入工作气隙对数因子、列出磁路统一方程、进而建立永磁负载线统一数学模型后,给出了求解永磁工作点的统一作图法;最后应用该方法,分析并阐释了极化磁系统的动态工作过程。The polarized magnetic system has a series of advantage and wide application. To determine the working point of permanent magnet is one of basic content of the polarized magnetic system’s research. It can provide condition for further analyzing and calculating the polarized magnetic system. The diagrammatized method that can be only used in the polarized magnetic system with single permanent magnet at present has characteristics of clear physics concept, compendious and direct. This method is benefit of understanding the principle of the polarized magnetic system. This paper studied the diagrammatized method unified model of the permanent magnet’s working point in the polarized magnetic system with single permanent magnet, which included differential and bridge types. After importing the twin gene of work clearance and listing the unified equation of magnetic circuit and setting up the unified math model of permanent magnet load line further, the unified diagrammatized method for determining the working point of permanent magnet was given. The dynamic working process of the polarized magnetic system was analyzed and explained by applying this method.
