    • PURPOSE: To increase repulsive force with a low cost structure by interposing a single pole magnet which is attached to a prescribed surface of a yoke in a condition in which a multi-pole magnet is separated from each other, and whose magnet pole is formed in the direction different from the magnet pole direction, in a part separated from the multi-pole magnet, in a magnet circuit attached to a suspension unit and the like. CONSTITUTION: A magnet circuit M1 is formed in such a constitution that two pole magnets 8 whose magnet pole is formed in the vertical direction to a prescribed surface of a rectangular yoke 6 (or two single pole magnets 8a, 8b whose different poles are faced to the same direction) are separated from each other and a single pole magnet 10 is interposed between both magnets 8a, 8b. Same magnetic poles of the both magnets 8a, 8b and the magnet 10 are faced to each other at a magnet end face (upper face) of a side opposite to the yoke 6. In the magnetic circuit, multi-pole magnet such as a three-pole magnet and four-pole magnet may be employed. When the multi-pole magnet is separated and a repellant magnet is inserted between separated and adjacent magnets, a magnetic field gradient is changed, and thereby, repulsive force of the magnetic circuit can be increased.
    • 目的:通过在多极磁体彼此分离的状态下插入安装在磁轭的规定表面上的单极磁铁,并且其磁极形成在其中,以低成本结构来增加排斥力 与磁极方向不同的方向,与多极磁铁分离的部分,安装在悬挂单元等的磁铁中。 构成:磁铁电路M1形成为在与矩形磁轭6的规定表面垂直的方向上形成磁极的两极磁铁8(或者两个磁极不同的极点相对的两个磁极8a,8b) 相同的方向)彼此分离,并且单极磁体10插入在两个磁体8a,8b之间。 两个磁体8a,8b和磁体10的相同的磁极在与磁轭6相反的一侧的磁铁端面(上表面)处相互面对。在磁路中,多极磁体如三 极磁体和四极磁体。 当多极磁体分离并且在分离的和相邻的磁体之间插入排斥磁体时,磁场梯度被改变,从而可以增加磁路的排斥力。
