pole, i.e. 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if required by the process. A six pole motor will be larger but will have a beneficial impact on thermal ratings of the gear reducer and noise.
