Topic tags/keywords: electrical current conversion band saw 220 to 110 voltage conversion

I just purchased a 2003 Laguna 14 band saw and would like to convert the motor from 220 to 110. The manual says the motor is 1.7 HP, 15 AMP. though one on of the black wires has a tag labelled “20”. There is a schematic in the cover that depicts two wiring options, but I cannot interpret it. I have included both the schematic and a picture of the wiring. Can someone tell me what I need to change? Thanks.

This link should show images of both the schematic and the actual wiring. Bob

Bob, I don’t see a link, but in the pic the right side drawing shows one L and one N, I’m guessing that’s the 120V wiring (one hot and one neutral). If the missing part of the pic (the left side) shows two L’s, that would be the 240V (2 hots). Having the missing stuff and the link would be useful.

I’m sure you don’t wanna hear this, but I would “consult a qualified electrician”. LOL

It is essentially a “jumper” change. In the picture above there are 2 metal strips oriented horizontally. Orient those strips vertically, and change the plug to a standard 120v.

Great. That seems almost too easy! I’m trying to avoid adding a 220 v circuit, but is there any downside to this? The plate on the saw says KW 1.1, v. 220, hz 60. The spec sheet in the manual says 220 single phase or 110 single phase, 15 amps.

In your situation there really isn’t a downside. The motor is more efficient @ 220v, but very functional at 110v. If you are using an extension cord, keep it as short as possible and of proper gauge. If you’re going straight into an outlet, everything is fine.

Looking at the pictures, something does not look right. If the jumpers should be in the horizontal orientation for 220 then the left diagram is for 220 volts. But I see a Neutral (N) and a Ground (PE) but only one hot wire (L) where is the other hot wire connecting to?

Maybe my photo of the actual wiring is upside down compared with the schematic. When turned the other way, the photo seems to conform to the schematic with the two black wires going to U1 and W1. Does that make sense?

that schematic only lists how to reverse the spin on 220. I dont think that motor can be wired for 110.

Not all motors can be 220/110 that picture looks like motor reversal indicated by the arrows at the bottom.
I agree with crashn there should be a tag on the outside saying 110/220.

”that schematic only lists how to reverse the spin on 220. I dont think that motor can be wired for 110.”

”Not all motors can be 220/110 that picture looks like motor reversal indicated by the arrows at the bottom.”

Good catch guys!

What is the model number of that saw?

I would leave it at 220 if you can motor will rum more efficient and produce less heat. I read this a long time ago in one of the wood magazine’s.
