I’m curious, has anyone managed to convert the ‘so called’ 2hp Harbor Freight dust collection motor from 110v to 220v? I’m a big believer in doing this whenever possible, since it divides the amperage in half, and greatly prolongs the life of the motor. I did this 34 years ago, when I purchased my Craftsman tablesaw and air compressor, and I haven’t had ‘Trouble One’ ever since.

I’m not all that electrician savvy, and I’m not even sure if this is possible. But if possible I’m ready to give it a go. I just purchased the system early this week, and am customizing it by using two Thien seperators for both the first and second stage, and then plan to vent the extra fine particulates outside.

Thanks for the consideration.

John

The motor label should say if it’s possible, it will be labeled duel voltage as in 120v/240V. That said, I can’t recall anyone mentioning that it is. (Obviously, I don’t have one.)

The one I have, as it comes from the factory is not able to be converted, to 220V.

I do wonder if a “hack” is possible….
But I don’t know enough about motors, to even contemplate it.

If it doesn’t have 120/240 listed on the motors data plate, you are SOL. And according to the manual for the current 2hp system, it’s a 120v only setup.

I would imagine there would be a ‘hack’ somewhere. I’ve given it a cursory look, but haven’t found it yet. If it really was possible, it would be nice to know about. I’m sold on the 220volt system. My two most important electric tools, the table saw and air compressor, are running on it, and I have not had a single problem in over 34 years. As the Timex commercial went, “They take a licking, but keep on ticking.”

I’m just hoping that somebody has access to this.

You are indeed correct Brad. I too saw all the umpteen cautions written in the owner’s manual. However, there are many people who view that as an open invitation to experiment. I’m sure someone has attempted this somewhere. I’d just love to know how it came out.

Lots of motor myths out there. Increases life of motor, runs cooler, more power! Nonsense! I’ve had 3 phase 440 volt motors converted to 220 volt so I could run them on my phase converter. The “motor shop” taps into the windings.
That’s the secret. Talking on Lumberjocks all day isn’t going to reveal any secrets except the one I told you. Call your motor shop and learn all the real secrets about your motor. You will probably find it cheaper to buy a new motor which may cost more than the dust collector.
BTW. Have them explain the motor myths to you. I assume you got your info on the web and not from an electrical engineer!

LOL – indeed! A motor designed to run on dual voltage (120/240) has separate windings which are run in series for 120v and parallel for 240v. Trying to get a single voltage motor to run on a higher voltage that it wasn’t designed for usually ends with letting the magic smoke out of the motor. There are not a lot of advantages to running on 240v instead of 120v, and certainly not enough to, IMHO, to risk trashing the motor (or worse) trying to do so.

Cheers,
Brad

Rick, please note that I asked if this had been done, out of curiosity. I think you are reading a bit more in it than I intended.

And I told you the motor shops are the only ones who can do this. Have you ever talked to a motor shop and asked how they could change the voltage of the motor and if it would do what you think it would? Be nice if someone would start giving the facts. I have a motor shop I work with and I can’t help but laughing every time I read the junk on the web about motors and electricity. It’s actually pretty pathetic in the long run.

Rick, I’m terribly sorry I am not so well versed in the fine art of electric motors and its a shame that I didn’t pursue an EE degree at the Citadel. But I do know a good bit about geology, Paleotology, and am a graduate Physical Anthropologist. I tend to cram my brain with all sorts of things you may not understand, or even care. But to me, they are important. That is why there are people, such as yourself, to do other things for others, and also make a living at it. Should we quiz you on your knowledge base with the sciences?

I somehow thought we were all here to help, rather than ridicule. To the best of my knowledge I asked a straight forward question: was it possible, and had it been done. Basically, that’s it. Because I am a curious hominid, that’s why.

What they said. If it’s not marked its not possible because it doesn’t have a second set of windings to put in parallel or series for the different voltages.

I’m not trying to ridicule you at all. My job is problem solving. If I have a geology question I call a geologist. You seemed to think someone here may have figured how to run a 110 volt motor on 220. My point was to ask the source that could give the correct answer with the least amount of questions. I never even implied you should have an electrical degree. If you cut your finger on a table saw you would go to a doctor not a woodworking forum.

I am trying to help. Trying to teach problem solving with the least amount of steps. You don’t have to have a degree in every field but having
Experts you can go to can go along way. You asked a question and I just wanted to give you the shortest way to the answer.

Actually this is a good place to ask this question. There are guys here from all walks of life. I work selling motors and motor repair.

The answers given are correct, unless the motor is labeled for 120/240 (dual voltage) you cannot change it to 240V. There will be no “hack” to make it 240V if it was not designed that way.

We actually get similar questions a lot. But we never laugh at people for asking. That is how you learn, by asking.
