Bi-Voltage Induction Motor

What's a bi-volt motor? or do you mean dual-voltage?

Bi-voltage/dual voltage, the blurb I could find on the internet mostly called it the former.

If the wires are as you describe, that is not a dual-voltage motor.

Thanks for that. This was my own thinking also but wondered if taking the capacitor out of circuit......???

Throw the motor out, Boss, and fit one of the same power rating that runs on your local voltage. I wouldn't like to be in the area if you plug it in and it's wrong.

Thanks for that. I already tested it on 110v & it just buzzed unhappily!

Bi-Voltage usually means tow TPYES of voltage, as in AC/DC... Dual Voltage means two different LEVELS of voltage.

If it says "Bi-Voltage" on the nameplate but only lists one voltage, it's likely what we here in the US call a "Universal" motor, it can take 220VAC or 220VDC, it works the same either way. That is what is commonly used in small HP portable power tools.

The big clue is, does it have brushes? A Universal motor has brushes. If you are not sure, look at the end housings when it is running in the dark and if you see little blue sparks, those are from the brushes and it is an AC/DC Universal motor. But they are never dual voltage as far as I know.

JReaf, thanks for your post. It's an brushless induction motor & the name plate definitely says 110/220v 60Hz which means it is A.C.

PS I loved Michael Palin & the Monty Python sketches also!

Wait a minute. If you have the nameplate and it says 110/220 it is dual voltage. There should be a wiring diagram showing how to reconnect the leads, or possibly a small switch somewhere on the motor or the additional wires are tucked out of sight. Maybe there is another connection box somewhere on the motor? (I'm pretty sure if you take the capacitor out of the circuit, you are going to let the smoke out.)

very useful to learn about bi-voltage

tks.

There was a reason the previous owner used an inverter so why not do the same, get a 110-230v inverter or change the motor.

Hi

In the movies it is always the Red Or Blue Wire that should be cut!

I don't think that by changing the electrical connections that this would be an easy fix, you would have to study the windings to sort this out

Cheers,

As others have stated, along with what I would do is:

Look at the nameplate. It should give a wiring diagram from 110 vac to 220 vac.

Check the model number and call the manufacturer for information

Lastly, go online and search for the manufacturer and model number for technical information.

Thanks to you all for posting. I have a inverter/transformer that I've been using, but as the motor plate says 220/110 volts, I was wanting to try using it directly from mains (110v).

The motor is on a 16" scroll saw, made by Ferrari - possibly here in Brasil but I think more likely China & rebranded here - but nothing so far on their web site, will keep looking. Strangely enough, the safety labeling on the tool is in English rather than Portuguese.

No information about motor manufacturer other than Type YYL5614, 120w induction motor. Googling that got me nowhere unfortunately but will keep trying.

...and if the diagram isn't on the label, it could be on the underside of the wire junction cover...
