Brad, Got this idea in the middle of the night.

Take your motor on the bandsaw apart, remove the rotor. Have a long solid shaft made that will stick out each end of motor like it's a double shafted motor. This may require a little machine shop work. You may need to drill the one end of motor so shaft can stick out. You may have to use locking colars to hold shaft in place. This will allow you to attach a large pulley to the shaft sticking out the back side of motor. The bearings of your old motor will hold the shaft where needs to be.

What do you think?

Hey George!

Now that is thinking "out of the box". I am considering several ideas, one of which is very similar to your idea.

The latest version: I am bidding on on a military surplus three phase diesel generator that outputs several voltages. Not the most convenient option but with electric rates here sky high might save money in the long run.

Thanks for the idea George. I may just use it.

Brad,
I'm far from being an educated electrician, but I think the military doesn't use 60 hz. Instead it's something like 400 hz and that will not work on a motor designed for 60.

Get an expert's opinion before you spend money on something that won't work.

Unless things have changed since I retired, the milirary used 50 cycle generators,60cycle generators and 400 cycle generators, 50cycle was used mainly overseas where it was desireable to syncronize with the local power grid. 60 cycle was used where syncronization was not needed and stateside. 400 cycle was used for sophisticated communication gear. Each cycle speed has its own standard voltages, take an expert with you and be careful.

You are NEVER cheaper to generate with diesel than to buy power from the electric company.

400 cycle (or Hz) was used on large mobile equipment especially aircraft. Devices with windings required much lighter iron cores for 400Hz than for lesser frequencies-- so one advantage would be weight savings. 400 would be good for welding or for rectifying to DC.

The only place the military uses 400 hz power is aircraft generators and maybe for radar systems still. There was a short period they tried to switch everything over to 400 hz but it didn't work out. For the last 20 years almost gensets are capable of 50hz but usually run at 60hz.

Rectification of 400hz gives a much smoother DC than 60hz does, if that matters.

Hey George.

This particular one is a 60hz 3 phase model that outputs from 208 to 460 volts.

Brad,
I thought you needed 560 vac. Not real sure how a 3 phase motor will work on lower voltage. What country was the bandsaw from?
