### Calculating the G force of a Vibrating Screen

08/07/2015· To do this, you will need three pieces of information: Number of poles of the motor Stroke of the screen Frequency of the current to the motor From the number of poles of the motor, the moto's shaft rotational speed can be calculated, using the following formula: w = / n where: w = shaft rotational speed, RPM f = frequency, Hz n = number of poles
