Regarding Benelson's quote of Jan 7th: 4 pole shaded AC motors run at 1800 rpm unloaded, and about 1725 rpm at full load. Everyone most likely knows this. We can buy slightly used AC motors on the internet for $500.00. Ditto. But not one 60 hertz motor has any expectation of staying together at any higher speed. Or, for how long? I would think anyone going into AC drive should find a motor rated at at least 5000 rpm, to avoid the constant shifting, or, EXPECT to shift. Kindest regards to all, williamson
