Title: (EN) TORQUE MOTOR WITH MECHANICAL FLEXURES ESTABLISHING ARMATURE-TO-FIELD GAPS
(ZH) 具有建立电枢至磁场间隙的机械柔性部的力矩马达
Abstract: front page image
(EN) A torque motor has a mechanical reference member, an armature, and a field assembly. The field assembly includes field pole pieces defining a pole opening, and the armature is mounted to the mechanical reference member for rotation about a motor axis and extends into the pole opening with respective gaps to the field pole pieces. The field assembly is secured to the mechanical reference member andspaced therefrom by elastically deformable flexures, deformed sufficiently to locate the armature at a predetermined position within the pole openings with corresponding lengths of the gaps. During manufacture, a load can be applied to move the field assembly relative to the mechanical reference member against the deformation force of the flexures to locate the pole opening relative to the armature pole piece such that the gaps of desired lengths are formed.
(ZH) 力矩马达具有机械基准构件、电枢和磁场组件。磁场组件包括限定磁极开口的磁场极靴,电枢安装到机械基准构件上用于绕马达轴线旋转,且延伸到磁极开口中并且到磁场极靴有相应的间隙。磁场组件固定到机械基准构件上并通过可弹性地变形的柔性部与其间隔开,柔性部变形到足以将电枢在磁极开口内定位在预定位置处,使得间隙具有相应的长度。在制造期间,可以施加载荷以使磁场组件克服柔性部的变形力而相对于机械基准构件移动,以相对于电枢极靴定位磁极开口,使得形成所需长度的间隙。
