Encoder RPM and Frequency - quick one
PostPosted: Tue Feb 03, 2009 9:36 am     Reply with quote
The formula to find RPM is below:

RPM = ((F(Hz) * 60)/PPR)

Is there another way of finding the RPM without knowing the PPR???

Yes.

If the encoder has an index pulse.

Just see how often it sends an output.
