| hi guys,
Im in the process of converting a furnace blower to a work shop fan. The furnace has these specs..200/230 volts 3 speed.etc.. My question is i would like to convert this motor to a 115 volt where i can you use regular house voltage to power it. Can this be done..I know a 230 volt has 2 power hot wires. how ,if possible,can i convert this to 115 to wire to a regular extension cord and outlet..thanks |

| You can leave the fan as is and run a 220/230/240 line to the workshop. It's the same type of line as an electric range or electric dryer so you have it in the house. Or check out the link. |
Here is a link that might be useful: 220 on 110 lines
|
| i was hoping to just wire it differently if possible.. |
|
| There are too many variations to give you a definative answer. I've tried trial and error, but error resulted in a smoking piece of junk. Some motors have alternative wiring schemes on the inside of their electrical connection cover plate. If it's not there, you might try taking it to a motor repair shop for them to look at. |

| it shows a varaition to make it 200 but not 115.. i have wiring diagrami can post if that helps |
|
| It may not be doable on yours, then. If you can find a motor shop, they might know a way. or If you know of a local company that installs replacement furnaces, they might have an old 115v fan in their junk pile. (I got two that way) |

| Are you sure that's not 208/230 volts? The name plate of the motor will list the acceptable voltages. If 115 isn't included it won't work. Buy a new motor or wire for 240v. |

| hendricus's link... is that a real product?! I built one once... that doesn't mean it was a good idea. What happens when your "120 to 240 adapter" is plugged into circuits A and B, a 240V load is connected, and somebody turns off the breaker for B in order to work on something? The entirety of circuit B remains live through circuit A and the load! That's a dumb product, and I'm sure that company will eventually be sued into oblivion. FORGET that idea. Just find a 120V motor or wire properly for 240V. |

| H'mmm... well, upon reading some of the details of that product, apparently they've prevented the scenario I mention, presumably with a relay or two. I still don't quite trust it, but maybe. |
