Okay I have a shaft that needs to be rotated. I want to use an appropriately sized motor to rotate said shaft. Torque necessary will not be a lot, it will be under 2 Nm.
What would be a fairly accurate way to measure the torque necessary? The point of this is for me to avoid buying a motor larger than I need (therefor adding cost), so the method to measure torque needs to be inexpensive as well. Any suggestions?
