How to Specify a Rotary Electric Vibrator

Rotary electric vibrators are grouped into 4 main rotational speeds. For 60 Hz conditions, the common rotational speeds to choose between are: 2 Pole (3600 RPM), 4 Pole (1800 RPM), 6 Pole (1200 RPM) and 8 Pole (900 RPM). The simplest way to think about rotational speed is: the faster the speed, the lower the amplitude.
