基本技术方案2.减小与磁石磁力反方向的吸力和斥力大小的方案
1.一个圆弧角度较大的提供磁场的静磁石或动磁石，提供磁极轴线的静磁石或动磁石，动磁石利用磁石磁力一般情况下正常运动。动磁石运动到静磁石的两端时受到较大的反方向斥力或吸力的阻挡，很易被停止运动。一个圆弧角度较大的提供磁场的静磁石的角度到180度时，出现动磁石在180度的中间90度处不受磁石磁力而停止运动。提供解决上述问题的方案如下：
将一个圆弧角度较大的静磁石或动磁石，分割为几个小磁石，其磁场方向与原样相同，角度相同，几个小磁石之间的距离相等，距离的大小与小磁石的大小有关。小磁石大时距离也可大。几个小磁石的首端及末端的吸力斥力已减小。
静磁石第一组几个小磁石在动磁石的下侧，第二组几个小磁石在动磁石的上侧，上下侧小磁石的磁极都指向动磁石的磁极。第一组几个小磁石的末端小磁石与第二组几个小磁石的首端小磁石置在相同的角度位置，有利于减小吸力 斥力。
动磁石与静磁石之间的距离要选择正常。其距离太小时，动磁石受到几个小磁石之间的磁石磁力吸力斥力三个力；其距离太大时，动磁石受到的磁石磁力将减小；选择其距离刚刚没有吸力斥力的地方。几个小磁石之间的距离小时，动磁石与静磁石之间的距离也小。
一个圆弧角度较大的静磁石或动磁石，圆弧角度控制在120度以内，90度更好。在圆弧角度的中间度数处不再有磁石磁力的停止运动。
2.单个的圆弧状的提供磁场的静磁石，或单个的圆弧状的提供磁极轴线的静磁石，在动磁石的下侧有两组几个小静磁石相邻空间的位置时，圆弧状的静磁石置于此处位置的动磁石的上侧或下侧，将其中心置于动磁石的中心处，将其的两端置于动磁石的外侧或内侧，也减小了吸力斥力。
提供磁场或磁极轴线的圆环形静磁石，提供90度(或60度等)，在动磁石的下侧0度至90度，180度至270度各置放一个，其中心置于动磁石的中心处，将其的两端置于动磁石的外侧。在90度至180度处也置放一个，在动磁石的上侧或下侧。动磁石在0度至270度有较好的磁石磁力而运动，有极小的吸力斥力不影响运动，也减小了吸力斥力。在270度至0度位置利用一个电磁线圈，在动磁石的上侧，通电后也产生磁石磁力，动磁石就会在360度完全继续运转起来。
