Series motor needed
(OP)
I have dredged and Googled vigorously, but have not come up with a suitable motor. I need a 120VAC motor with easily varied speed and maximum power about 1/2 hp at 5000 rpm.
Any thoughts?

Just because you can't find it on Google does not mean it cannot be done.

They have both HVDC and Universal motors.
Problem is, the universals run anywhere from 20000 to 40000 rpm, so you need a reduction gear.
When you look at the portable power tools like the Sears saw, they actually use high speed universals with reduction. They use the same motor without reduction for router, for instance.

Johnson was a good clue. I rechecked my fan calcs for 20,000 rpm-Pitch becomes too low to be practical. But I can go with a larger hub diameter, which eases the pitch problem.
Would still like to find one at 5,000....

The closest to your requirements is a HVDC (120 V) delivering about 200 W, which is a bit below what you are looking for. However, with a bridge rectifier in front of it, it would be an easy solution. Johnson part number is HA03005.
