The Surplus Center I believe has both 110 and 220 volt vacuum motors pretty cheap. http://www.surpluscenter.com/

ps Maybe we should have a LINKS area where we could send people for the typical "source" type questions. It might already be there.

i wonder how superflow do 220 volt macines if they use the 110 v motors , maybe they stuck in a BIG transformer.!

Super Flow hooks the white wires together on the two 110 motors and runs one black wire to each 110 volt leg. This makes the motors act like shunts for each other I have been told. They have gotten away with it for years but I personally like the 4 wire (Black, Red, White, and green wiring with a neutral being used as well as a ground with two "legs" of
power (Half on the RED side and half on the BLACK side the way house wiring is done.

If you fail a motor on the SF wiring it will kill the second motor on that circuit too.

With the 4 wire scheme you can have a motor go bad and still run the other motor next to it.

thanks thomas , my microscopic brain ,reads what your saying as , i take 2 110 v motors.. connect my pos 220v to the two pos on the motors ,then take my neutral 220v and stick it on the two motor neutrals ,no that cant be right #### , maybe you mean like a chain in series ,my 220v pos goes to motor no1 pos. then mot1 neutral goes to motor no2 pos, then motor no2 neutral goes to 220 v neutral ?? regards robert.

I need some help understanding...

Superflow benches use a 110v 115923 motor. The Superflow site says a SF600 has 8 motors and requires a 37A Single Phase 240v. The Pro Bench uses 16 motors and requires 75A Single Phase 240v. I also checked the FlowData site and they use 8 motors in the small bench and require a Single Stage 50A.

I've read on the forum you can wire these motors in series, two at a time. So, with this style brush motor, a 110v, you can run it at 240v to cut the amps in half? Each motor is rated at like 11 amps. I think this is what I'm reading.

Anyone have a clear drawing of how to do this? Do you need all the relays like the article bench? HELP!!!!!!

ah thats what i was guessing chad

this is what i found today at the yard ,too small ? or would this be a better solution with a 3 or 4 hp motor on a pulley gearing it up to say 5 k ,its at 2800 rpm at the mo with a puny .55kw motor ,what do you think out there?stick wirth the 8 small vacuum motors ? regards robert
