I would think a standard 56 frame motor and gear box would fit inside 
Rohn 45.. A 56, 143, or 145 frame is about 6.5" in diameter, and Rohn 45 
is something like 14" across the middle

I can see a 5-7 HP unit in a 184T frame (9" in diameter) being a tight 
fit, but then, there are companies making long skinny motors (e.g. for 
well pumps).
