Another thing that's rarely mentioned is that single-phase motors don't like being repeatedly stopped and started,
You can overheat and burn out the start winding, as the start winding is normally only rated for (very) intermittent use.Why?
I've abused single phase motors with multiple reverses and never blown one up but I have made them get hot. I did have one motor that has on the data tag x number of starts per hour. It wasn't many perhaps 15 I don't recall.

Nothing keeping you from hanging a 4" computer fan on the back of the motor.I've abused single phase motors with multiple reverses and never blown one up but I have made them get hot.

That would likely depend on if the start winding has been designed/positioned to be suitably cooled by the air flow.Nothing keeping you from hanging a 4" computer fan on the back of the motor.
It's in the same slots as the main windings.That would likely depend on if the start winding has been designed/positioned to be suitably cooled by the air flow.
However, I'd be more inclined to just fit a 3 phase motor and VFD now.
For a few hundred pound, I think you end up with a far more useable machine.
As soon as the motor stops, or even drops below about 75% speed, the cap is shorted through both windings, so that seems unlikely.The 15 starts per hour is due to the capacitor needing to discharge apparently.
