I just wanted to know, how could I measure the RPM of a moving metal disk?
The problem that I am having is that I can’t utilize a typical Hall Effect Sensor, as my experiment is related to Magnetic Braking, so adding another magnet into the mix, can play havoc…
I did look at Rotary Encoders, but am so far unable to find any evidence of them being utilized for RPM sensing purposes.
For clarity, I will be using a setup similar to the image that I have attached. There will be a DC motor on one side. The other side will not be used.
Thanks for Reading!
