I checked them when I was originally just trying the wiring by changing the lead arrangement on the head motor. Thanks!

Thanks, this seems to be a 5 minute job then. This will enable me to run more that one machine at a time as the 440>220 setups prevented this. Thanks again!!

Thanks, so you are saying that I need to connect H1 to H3, and H4 to H2 and then I have to go to the head unit and change the wires there so it can run in 220v as well correct? Thanks!

Here’s my setup. thanks.

I'll check when I get back to it one day this week

I do not think he changed any fuses. Like I stated it was originally set up on 220 when I bought it so I really don't think it would have been necessary for a 440 setup. Reverse the scenario's then I agree, those would need to be looked at. Thanks

Little backstory. The mill was (when I purchased it) wired to a 220 with a stinger leg. I moved locations and the power in the new building was 480 with a transformer and the "local there" electrician said, let's just wire everything on 440. What the hell I said as it works it works and I...

Let’s not gloat as many people have successfully rewired an electric motor from 220 to 440 and vice versa, It’s not rocket science and the amazing thing is, the manufacturer even tells us how to do it On the Motor cover of all places. I appreciate your help and feedback though.

Thanks

I’m certainly not an electrician. Basic wiring is not a problem and I can trace out a wiring diagram. Next time I am at my shop I’ll locate T1 & T2 and look for the wires. Thanks

I swapped the 6,5,4 and 1,7- 2,8 - 3,9 together in the past to try to get the motor to run on the 220V and when I jumped the relays in the back of the machine the motor would work but......

I’ve rewired the quill motor but it doesn’t run unless I jump the contact’s in the back of the machine and it will only run in one direction but when the machine is put into low range or high range, the rotation will need to be changed and problem #1, problem #2 is the fact that it’s not safe...

Thanks, I’ll look into this

It's a Bridgeport Series II and there's more to the mill than just the 1HP (could be 2hp come to think about it) motor as there's a large electrical panel on these machines and they are using the 440 wiring in more places than just the motor. Else, that'd be a great idea.

That's a lot more $ and work than a switch
