I’m building a pitching machine that has an 8” wheel (16” OD tire) that is directly mounted to a 1/2” motor shaft.
Most similar questions reference a gearbox or pulpy system, but my situation is directly mounted to a 12v motor shaft.
Due to motor/fabrication design, the closest I can get my magnetic rpm sensor is a radius of 5” from the shaft.
So known variables for the calculation will be RPM at a diameter of 10” and the OD of the tire at 16” all on the same wheel.
How do I calculate the speed (MPH) of the tire?
I would imagine the OD of the tire runs slower than the shaft.
I hope this makes sense.
