Abstract: Detent systems for rotary actuators that utilize one or more sets of magnets that have either attractive or repulsive characteristics. A biasing magnetic element may be positioned to repel a floating movable magnet. The repelled movable magnetic element is forced into contact with a serrated detenting ring via the repulsive force between magnets of common pole. As the detenting ring is rotated relative to the biasing magnet, the “floating” magnetic element is forced closer to the biasing magnet. The repulsive force drives the floating magnetic element into the next recess detent causing the rotational component to snap to the next detented position. The magnetic element rolls about its longitudinal axis as the magnetic element moves from one detent location to the next, which results in rolling friction that tends to cause significantly lower surface wear and increased life.

Abstract translation: 用于旋转致动器的定位系统，其利用具有吸引或排斥特性的一组或多组磁体。 偏置磁性元件可以定位成排斥浮动的可移动磁体。 排斥的可动磁性元件通过公共极的磁体之间的排斥力被迫与锯齿状的锁定环接触。 当定位环相对于偏置磁体旋转时，“浮动”磁性元件被迫靠近偏置磁体。 排斥力将浮动磁性元件驱动到下一个凹槽制动器中，使得旋转部件卡扣到下一个棘爪位置。 磁性元件随着磁性元件从一个制动位置移动到下一个位置而绕其纵向轴线滚动，这导致滚动摩擦，从而导致显着降低的表面磨损和增加的寿命。
