Hi everyone, I have a chinese mill that looks like the smaller brother of an RF-45, but the motor that came with it is toast. I'm trying to source a 3-phase replacement but I don't know too much about motors, and this thing is very definitely not a standard nema size. I'm trying to find a motor that will fit, either as a direct replacement, or if someone can recommend some kind of adapter strategy to use a common size motor...
Anyway some numbers-(I really hope I got the nema dimensions correct)
Shaft diameter (U) 0.5 inches
Shaft height (NW) 1.125 inches
Face diameter (AK) 4.375 inches
Face diameter (P) 5.825 inches
mounting hole diameter (AJ) 5.1 inches
4 holes, 0.4 inch diameter, arranged in a square 3.6 inches on a side
there's a flat on one edge, to clear the mill column. Actual distance from center of shaft to flat is 2.65 inches.
What am I dealing with here?
Any help is incredibly appreciated!
