摘　　要：提出了一种低速永磁直线同步电动机的结构形式,分析了其运行原理。在此基础上,给出了电磁推力的计算公式,并推导了最大电磁推力的表达式。根据最大电磁推力的要求,确定了次级永磁体的高度。The paper provides the structure style of a kind of low-velocity per-manent magnetic linear synchronous motor, and analyses its opera-tion principle. On the basis of which, it also offers the formula forcalculating the electromagnetic thrust, and deduces the expression forthe maximal value of the electromagnetic thrust. According to therequirement of maximal electromagnetic thrust, the height of sub-stage permanent magnet is determined.
