Quote: Is 1750 the American speed of 2 pole motors or am i getting confused, do they use 60HZ for domestic supply?Yes, 60Hz essentially everywhere in the US. Synchronous speed for a 4-pole motor is 1800 rpm, and the speed at full load is typically 1725 or 1750 rpm. The synchronous speed for a 6-pole motor is 1200 rpm and a 2-pole motor 3600 rpm.
