I'm trying to get my mill up and running and can't I'D the motor.

Mill is a 1967 step-pulley Bridgeport with a 9 x 32 table and what appears to be the original pancake style motor. I can't find the motor data plate and I'm looking at installing a VFD (no 3-phase in the shop). I'm guessing 1, 1-1/2, or 2 hp and am leaning toward the 1-1/2 hp. I don't mind putting a slightly oversized drive on the mill, but I still need the motor data for RPM and FLA so I don't wind up overloading and burning out the motor.

Can anyone help me ID this motor?

kyfho: A buddy of mine has a BP of similar vintage and size with a pancake motor and his is a 3/4 hp. I think he said his a '71.

1965 9x32 mill

1HP Frame 56

200V=3.8 Amps
230V=3.3 Amps

Motor type = JV

Built by US Motors

From the face of mounting flange to top = 7 inches

Diameter = 9 inches

This motor original to the machine

Exactly like my 1964. I use a 1HP VFD from Automation Direct and it works fine.

OK, thanks for the replies folks.

After chipping off multiple layers of paint, I did find a 2" diameter tag on top of the motor shroud and found a red label with an "F" and "M" with a hand raising a weight. Some internet digging found this to be a Fairbanks Morse motor.

After talking to Jerry @ H & W, he helped ID this as a 1 hp, 3 ph, 1745 rpm, with a 220 volt and 4.2 FLA.

I will be ordering a VFD from Automation Direct this week.
