中文摘要：

长初级直线电动机在实际应用中常需要将初级分段，并采用分段供电的驱动方式，其意义在于可以提高效率、节约电能并减小对电源容量的要求。首先，分析了磁悬浮列车所采用的分段供电技术并不适合于其它工业或军用领域的原因。其次，在充分总结国内外各种结构长初级直线电动机的研究现状的基础上，对分段供电方法进行了分类，并系统概括了分段供电技术需要研究的主要内容。最后，指出了直线电动机分段供电技术的热点应用领域和发展方向。

英文摘要：

The significance is increasing efficiency, saving energy and reducing power capacity, for segmenting the long primary linear motor into blocks and using block feeding methods. The analysis indicates that maglev train＇s power supply ways are not suitable for other applications in both civil and military use. Based on the internal and overseas actualities of various structures of long primary linear motor, the block feeding methods are classified and the main points remained to be studied are summarized. At last, the hot application fields and development directions are put forward.
