DIY dynamometer (friction torque meter) using 3D printer

I design this friction torque meter to study the performance of the motor, gearbox, and other stuff. It is also a dynamometer to measure the torque and the rotational speed (RPM) simultaneously for motor or rotational engine. Now the dynamometer is only suitable for small torque regions. Next time I will upgrade it for much high torque region measurement. Please like and subscribe.
Hope you will like it.
I like to make some new and useful stuff using 3D printer. This is not the first attempt but I think it is a good example to get new ideas to make things smooth. I wish someone will get some idea through the smallest thing. Also, I hope they will share the experience with us making the world a better place. Don’t forget to subscribe to this channel. Your support is my best happiness. I will continue to update the video. I hope it will give you some help. Thank you very much.
