Motorized Goniometer, ±45 ° Travel Range, Full-step Drive, BGM160

The BGM160BPE 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 BPE 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.
Precision Multi-Axis Assemblies
BG goniometers are designed so that two adjacent-sized models can be directly mounted orthogonally to each other (for example, BGS80 with BGM120) to pivot about the same point in space. The direct mounting capability saves set-up time, design time, and adapter plate costs. For additional rotation axes, a rotation stage can be mounted under the assembly or on the top BG platform. The video demonstrates an open access, multi-axis tip, tilt and rotation assembly with two BG goniometers and two rotation stages.
