Calculate the Revolutions Per Minute (RPM) of the Compressor Flywheel or the diameter of the Motor Pulley

Many times we have noticed users ask us how to determine the revolutions per minute (rpm) of the air compressor without using an rpm checking device.


Or they would ask that after changing the electric motor from a 50Hz to a 60Hz frequency the rpm of the motor is higher so what size should the motor pulley be to ensure the same effective rpm on the compressor flywheel.


Sometimes users replace electric motors which are around 1500 rpm with diesel or other fuel based engines which are mostly around 2800 or so rpm. In such cases new smaller diameter motor pulley (engine pulley) will be required to drive the compressor.


Below is a free tool that you can use to get your answers related to diameter and rpm of both compressor flywheel and motor pulley.
