摘　　要：介绍U型无铁心永磁直线同步电机的基本结构,并对该电机内部磁场进行解析计算,得出了磁场的解析表达式,进而推导得出绕组相电动势与电磁推力的解析表达式;利用Matlab GUI用户图形界面,设计和开发了基于解析算法U型无铁心永磁直线同步电机的计算机辅助设计软件。采用实际的算例导入到开发的软件当中,验证了软件的准确性与实用性。The basic structure of U-shaped ironless permanent magnet linear synchronous motor was introduced in this paper. The internal magnet field was deduced through analytical calculation and its analytic expression was given. The analytic expressions of phase back-EMF and electromagnetic thrust were also deduced. The computer-aided design software was designed and developed on the basis of analytical algorithm about U-shaped ironless permanent magnet linear synchronous motor through the Matlab GUI. Rightness and superiority were confirmed by taking an actual example through this software.
