Vibration Frequency Calculator. This calculator can be used to either calculate the vibration frequency of an ERM from the motor speed, or the motor speed from the desired vibration frequency. Simply enter your new speed in RPM or frequency in Hz, if you have a specific motor in mind then both these values can be found on the datasheet.
