    For this reason rotational speed is typically set at a fixed value based on the size of the tools being used. If the rig has sufficient torque the speed can be increased to get higher penetration rates. Conversely if the head stalls under normal operation then the speed should be reduced to produce more torque and maintain steady rotation.

  • How to Calculate the Speed of Two Different Pulleys

    Calculate the speed of each pulley by dividing the drive speed by the pulley ratio. For example given a drive speed of 750 RPM the speed of the first pulley = 750/2 = 375 RPM and the speed of the second pulley = 750/1.27 = 591 RPM.

    The method uses multiples of rotational speed (orders) rather than absolute frequency (Hz). The purpose of using orders is to lock the display to the rotational speed (1X) and its multiples meaning that the ordered components in the spectrum always remain in the same position even if the rotational speed varies during measurement.
