I had the opportunity to get a 24” bandsaw that supposedly works for $100. It appears to be 30 years old and in good physical shape. My stepgrandfather, Ernie knows a guy that knows a guy, etc. Anyways he said something to me at Thanksgiving and he told me he would have bought it but he couldn’t use it in his garage. I asked him why, is it 220? He said it was 3 phase. I replied that we have 3 phase at school and want a large bandsaw. So he called the guy back and said I would get it at Christmas.
I don’t know how they got it in a pickup to begin with, probably a fork since it came from a factory. But Ernie had a hoist in his garage so that is how he got it out. I used a solid surface pallet from the cabinet supplier and a pallet jack to load it. Had to winch it into the trailer. Was told it weighs 800#. It took 4 of us to get it on the pallet, 800# my foot, more like 1G.
Anyways, got it home and then the next day wiped off the motor plate. Wouldn’t you guess 440v. Good thing it was just me an a maintenance worker, because I said some school inappropriate choice words. Our shop doesn’t have 440 power.
Here’s the question i have for the LJ’s that are good with electrical motors.
The motor is a 5hp, 3ph 440v 1150rpm with what appears to be either 1” or 1 1/8” shaft, about 3” long and a 1/4” key. The motor is about the size of a lear jet engine (exaggerating a little) but not much.
I have 2 motors that I can get my hands on that are 5hp, 3ph 220v, 1750 rpm, with the shaft measurements the same as the original. The motor is smaller in size and building a bracket out of some angle or blocks of wood to make it the right height isn’t a problem.
Can I use the 1750rpm motor? With my limited electrical background, wouldn’t it just spin faster. Maybe wear out the bearings a little quicker?
Or am I better off just selling to get my money back? I will post pics later this week.
Thanks for any suggestions or comments.
