Thanks to everyone that helped me get over the man-thing of
over-built... I don't see any brushless DC surplus, and their retail
price for 1HP is about the same as brushed DC.

I can't see a markedly superior performance of BLDC to PMDC.

There is one brand I know of, the PowerTec, but they come big....

Baldor has some nice ones up to 3HP, but probably not cheap.

You know you need a special drive for them, right (not a regular SCR
drive intended for DC motors). The commutation is done externally and
electronically.

Wow, Bodine has a 115ac drive that puts out 320vdc.
