3. 以电控方式控制物体的往复运动， 如电磁方式， 这种方式需要提 供非常强的电力来控制被控物体的运动。
4. 以热能控制物体的往复运动，如发动机等等，这种方式效率不高， 能源浪费严重。
发明内容 本发明的目的在于避免上述现有技术的不足，提供一种耗能少 的控制物体往复运动并获取动能的方法。 本发明是采用如下方法，这种旋转磁极控制物体往复运动并获取 动能的方法， 首先在沿预定轨迹运动的被控物体上设置有永磁铁， 该 被控物体连接负载；然后在物体的一侧固定设置一个在对合的磁轭中 孔内旋转并变换永磁磁极的旋转磁铁； 当驱动轴带动旋转磁铁旋转 时，旋转磁铁的 N极或 S极交替面对被控物体； 利用磁性物体同性相 斥、 异性相吸的原理， 将被控物体推离或吸引靠近旋转磁铁； 旋转旋 转磁铁不断驱动被控物体作往复运动， 同时使物体获得动能。 当旋转 磁铁的极性与被控物体表面上永磁铁的极性相同时 ,被控物体在磁铁 排斥力的作用下远离磁轭； 当旋转磁铁的极性与被控物体表面上 兹 铁的极性相反时，被控物体在磁铁吸引力的作用下而接近磁轭, 这样 就实现了控制物体往复运动并获取动能的目的。
