直线电机的控制
摘要：
直线电机是一种将电能直接转换成直线运动机械能，而不需要任何
中间转换机构的传动装置。它可以看成是一台旋转电机按径向剖开，并展成平面
而成。直线电动机的工作原理与旋转电动机相似。以直线感应电动机为例：当初
级绕组通入交流电源时，便在气隙中产生行波磁场，次级在行波磁场切割下，将
感应出电动势并产生电流，该电流与气隙中的磁场相作用就产生电磁推力。在本
设计中用单片机的IO输出端口来控制两个电机工作模式（正转、反转），而每一
个电机由两个继电器和LED来反映设计结果。

Abstract：
The electrical machinery of straight line is that one
kind changes electric energy into the mechanical energy of rectilinear
motion directly, And does not need to change the transmission device of
the organization in the middle of any. It can regard as one and rotate
the electrical machinery to cut open according to the radial, and the
exhibition became the level. The operation principle of the straight line
motor is similar with the rotating motor. Take reaction motor of straight
line as an example: Originally when one grade of windings was led to
