dynamometer (friction torque meter)

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.
