The M-BGM120PE metric Goniometer features a worm mounted rotary encoder for improved accuracy and repeatability. The encoder also provides a method for detecting motor stalling, an important feature for applications with high loads or torques. The PE full-step version with a reduction gear provides a higher torque and is recommended for high inertia payloads. BG Series goniometric cradles rotate on a transverse axis above the platform. Compared to full 360° rotation stages, they offer maximum free access to the rotating part and allow construction of very compact multi-axis rotation assemblies. BG cradles are designed so that orthogonal mounting of two adjacent-size cradles (e.g., BGS50 and BGS80) provides two perpendicular rotational axes intersecting at about the same point in space. Mounting a rotation stage under the assembly adds a third orthogonal rotation axis through the same point. Precision rotation is ensured by a precision ground, hardened worm gear drive. Single row ball bearings and precision ground tool-steel races ensure smooth rotation with minimal wobble and eccentricity. A home switch, conveniently located at the center of travel, facilitates the return of the platform to a level position.


M-BGM120PE公制测角仪采用蜗杆式旋转编码器，提高了精度和重复性。编码器还提供了一种检测电机失速的方法，这是高负载或扭矩应用的一个重要特征。PE全级减速器提供更高的扭矩，建议用于高惯性载荷。BG系列测角支架在平台上方的横轴上旋转。满360°旋转阶段相比,他们提供最大自由获取的转动部分,允许建设非常紧凑多轴旋转总成。BG支架的设计使得两个相邻尺寸的支架(例如BGS50和BGS80)的正交安装能够提供两个垂直的旋转轴，它们相交于空间中的同一点。安装在组件下的旋转台通过同一点添加第三个正交旋转轴。精密旋转由精密磨削、淬火蜗轮传动保证。单列滚珠轴承和精密的地面工具钢制滚道确保平稳旋转，最小的抖动和偏心。一个家庭开关，方便地位于旅行中心，促进平台返回到一个水平位置。
