i just got a metal lathe for free, just had to haul away the guy's scrap as well, haha. he wanted to keep the motor for his belt sander, but i thought how hard is it to find another motor and slap it on there.

the motor it had was a 1725 1/2hp 110 motor. i was wondering if its worth it to upgrade to a 220 motor or if i should just stick to a 110 1hp motor? thanks guys.

 

I would upgrade to a 220v motor of the same or more hp. Its pretty straight fwd swap

 

The only real benefit to sitching to a 220 motor is that it will draw basically half the amps.
Many of the newer motors esoecially hen you talk about 1hp are a dual voltage and can be wired for either. If you have it available then use the 220. If your not going to run the machine allot then don't worry about. Just be careful because boosting the HP will maybe stress the gears and break the lathe. stay with the same RPM

 

yeah we will not use it much. this one is for the home garage. so ill probably just stick with 110. ive seen a lot of 110 1hp motors that are 3600, should i stick to the 1800 rpm?

 

lolwut.

its kwh. not amps u goof

use the same rpm as what came off.

 

will do. thank you guys

 

yes technically your right but amps is draw which when multiplied by the voltage gives you kw which is what they base your bill on in kwh.

you can rate things in many ways but it still comes out the same. amps x volts = kw

this formula makes me realize that I made a mistake in my previous statement that the motor is 50% cheaper to run something I have been told over and over again for years. It is cheaper to buy usually and also cheaper to wire because it draws less amps so you can use a light gauge of wire and a smaller breaker. If your limited in the main panel 220 will also help. 220-240 volt motors tend to be more efficient

 

that is why i was thinking of going 220, but then again, this is just for general use...shorten up some drivelines and stuff like that.

 

I'd go 220v and get a 1.5 to 2.0 hp motor. In no time you'll be turning large items and wish you did it right the first time.

 

haha, i already see that day coming. thanks chris. same rpm though right?

 

the way it sounds is you can never really have too much hp, but the rpm is where you can go wrong?

 

Yeah, try to stick with the speed that the old one had. The rest of the machine was built for that.

Does this machine have a setup to adjust your speed? Belts or gears to change rotation speed?

 

oh yeah, its got three different belt combinations along with gears up the wall for different threads.
