Speed Conversion

You can convert pulse speed [HZ] ⇔ rotational speed [r/min] or belt and pulley linear speed [m/min].[m/sec].[mm/sec] ⇔ motor rotation speed [r/min]
Please use it as support tool for motor selection or setting up your machine.
Calculation results are displayed after you enter the setting number and press the "Calculate" button.
