R-80 Pneumatic Rotational Stepper Motor

thingiverse

The R-80 is a robust rotational stepper motor with a step size of 10° and maximum torque reaching approximately 3.7 Nm as seen in this video at 40 seconds. Measuring 80 x 80 x 37 mm³, it features a cylinder cross-sectional area of 30 x 20 mm², necessitating rectangular seals roughly 30.3 x 20.2 mm² in size which are conveniently included. Should you require custom dimensions, you can generate bespoke seal cutters using this resource. The axle is the only component requiring support, and the motor's pictured version features transparent top/bottom covers precision-cut from acrylic. Interested users may request 2D vector files for these components, or opt to print them themselves. As part of a project developing MR safe robotics for breast cancer diagnosis, the full model is not publicly available for download. However, design files can be accessed upon request, provided proof of commitment such as a picture of another model created by this designer or a donation of any amount is submitted. The R-80 is also featured on MyMiniFactory, where users can contribute to its development. For detailed assembly instructions, refer to the pneumatic designs such as the R-64 or watch the video accompanying the R-81.
