Just got this in the Lab yesterday. This is going to be the coolest motor once I get it restored! It was originally on a 24" jointer of 1910-20 vintage. Probably a line shaft driven machine converted to electric motor. Specs on the motor are unknown other than it is three phase. Probably 5 to 7 HP range. No data plates at all. Just love the styling though!
It's sitting on a 8" concrete block so that gives you indication of the size. Big! And very heavy! I assume the frame is cast iron.
I thought this was really neat. It has oil reservoirs and though it is hard to see, there are cast caps that swing up out of the way to fill the reservoirs and they have "OIL HERE" cast into them. Gosh I just love these old motors. A lot more character than any new Baldor.
