Butler 26" shaper motor size

Lanza · Aug 18, 2018

I'm looking at buying a Butler 26" shaper. I can't find the badge on the motor. It is 3 phase, but it looks like a 15HP motor. I'd like to know the size to see if it's suitable for my power supply.

Possibly 1200 RPM so frame size could be 324 if 15HP. Frame size dimensions are in Machinery's Handbook and other electrical related pocket books such as Electrical Engineering Pocket Handbook

Being a shaper, I agree with John, very likely a 1200rpm motor and 70yrs or more old. That means it will look twice as big as it actually is in terms of hp. The 5hp on my L&S lathe is enormous and weighs around 400lbs. The modern 5hp 1200rpm I use for my phase converter idler will rattle around in a 5 gal bucket and is maybe 120lbs. Looks like the old 1927 3hp Westinghouse on my radial drill.

For an Ormerod shaper - IMHO same meat different gravy as a Butler - for 26'' they say 9HP Ormerod Shapers Page 2
